This is going to be my first build. I am going to first upgrade the head unit, then i will add some mids and highs, then eventually subs. Current setup: Stock head unit Stock speakers (6x8) Considering the stock speakers are 6x8s, I will most likely have to re-do the entire door panels so I can fit 6.5s and tweeters. I am pretty new at this, but i have a good idea of what i am going to do.Will i have to re do the door panels if i want 6.5 speakers to fit? For a head unit, I would like to put in Pioneer DEH-2400UB, according to crutchfield.com it will fit. For Mids and Highs, I would like to put in 4 Selenium 6W4P and 2 Selenium ST200 tweeter. I dont know what amp to get, I was thinking about sundown or MB Quart. Once my camera is chargered and I am not busy i will post some pics. Stay tuned for more...

I have: Sundown SAX-100.4 in good condition- $275 shipped or trade for a Crescendo C1100.4 2x Sundown SD-2 10 d2s in great condition and lightly used- $250 shipped Cheaper for local pickup. Offer up... Lower 48 states only please...

Hello, guys. Sorry for the bad English, I translate through Google. Well. Let's begin. It is based on Russian-made car - four-door sedan VAZ 21099 It has long had the idea to implement the six twelve-inch subwoofer in a body. To start welded metal frame on the floor, the roof and the rear of the vehicle that would further secure the plywood to it. Just cut out the floor of the trunk, so that would be put to the battery compartment. At the moment, the subwoofer is installed. It remains to make the chat box front. Soon the rest of the news. https://instagram.com/justsound_customs/

I had another build on here but it is way out of date so I decided to start a new log.. My system consists of.. 2012 Ford Focus Kenwood DDX-370 Android Mini PC RK3188 (1) Sundown SA-6.5 CS (Front) (2) Sundown Neo Pro 6.5 V2 (Rear) (2) Sundown Neo Pro 8 V1 (Rear) (2) Sundown Audio SA-12 D4 DC Creations 4.5ft3 tuned to 22hz Hifonics BRX 2000.1D Hifonics ZXi 80.4 XS Power D6500 (Stock Location) 150A Alternator Plasti-dip on the hubcaps and 35% tint all around except the windshield

1999 Chevy S10 Running (2) Zv3-10's off of One NS-1 In IASCA Rookie Trunk/Truck I did a 147.6 Sealed off the windshield. (.3 DB down from the World Record) This was done with (1) battery XS D3400, (1) run of 1/0 Power wire, and Stock Alt. Also in IASCA I placed 3rd Overall in Flyweight with a 30sec. Average of 148 Which consisted of (2) batteries, and (2) runs of 1/0 Power I have recently dropped the power down to a saz2500 on the (2) Z's, soon to be a 2nd saz2500 and hopefully the new XS7500

I am looking to buy a single 15" subwoofer. I want something that excels at the 30hz-20hz range for under around $640 USD. Sundown is what i want but the shipping to australia always costs WAY too much. Also FI Car Audio does not ship to australia. The Skar Audio ZVX-15v2 costs $360USD + $100USD Shipping and seems to be what i'm looking for but people keep bad talking it. The amp i am getting is a 3200W hifonics amplifier so a higher wattage subwoofer would also be good if it can be found for the price. Does anyone have any suggestions for other brands to look into?

Hey guys, work in progress here! My brother over at Good Vibrations Audio is building my car.www.facebook.com/GoodVibrationsAudioFL Please check him out if you like the build! Thanks! GVA I'm Evan Otis and this is my build in my 2000 Ford Contour! Located: West Palm Beach, FL Goal: is to have a fully functional, clean sounding, & stable audio system! Bandpass box: 3:1 ratio with 2 SA Ultras on 2 2k Crescendo BC2000. Box Peaks at 37hrtz. Subs specs: 750 watt rms Front Stage: 8" Rockford Fosgate mids and super tweeters. Rear Stage: 6" Rockford Fosgate mids. All powered on a Crescendo C1000.4. Battery: Powersafe 190ah Alternator: Stock alt Here's a timelapse of the build & a short preview of it playing. Here's a video of it playing with my windshield seals blown out from bass. https://www.facebook.com/Lil.Otis.or...20?pnref=story (It's fixed now haha) We are making progress. Ultimately going to have LEDs in the box (plexi side). We are going to do an infinity mirror on the top of the box and maybe do some plexi engraving or plaques inside of the box representing GVA. Inside port we are still undecided. In the future I will most likely upgrade the subs to something that will handle more power! Current Scores are 149.3 was kick with driver door open and 149.0 was windshield driver door open. I'm confident that with some small electrical upgrades, reinforcing, and tuning we will get our 150db score from two budget subs! Making progress. Let me know what everyone thinks and I'll be happy to answer any questions! Will keep this thread updated with pics, vids, and info!

Feel free to comment, im always looking for things to improve and small projects to do. Its been too quiet and too long since I have had loud bass.. its time.. I have already got most of the parts for it have been saving and getting everything together since the winter months, the plan was to do a clean build with quality items and is front facing and sealed off from the trunk. I'm not going to upload all the photos at once so I will be trying to maintain an order since I never got around to making a thread about it the last 6 months Heres the car I just tried out some turtle wash and spray wax, Not sure if im satisfied especially with the pollen that was blowing all around.. Ill bust out the real wax next time. Getting stuff together some Sky High 1/0 OFC and 6 Lug Battery Terminals. XS Power D3100 for the trunk, aka stock spot. After ALOT! Of considerations I finally decided to save some cash and go with the hds 300 12s.. well see how they do. 5/23 More pics.. This was when I bought it 2 years ago. Put a Kenwood DDX470 into it soon.. was rough finding anything for this vehicle. I had to alter the dash mount I got.. and even after its still not a perfect fit, but its not noticable and now the radio actually fits in it I ended up redoing the 2 trim pieces around the shift knob and radio repaint and everything a graphite gray and put new boots on the shift knob and e-brake. Now I have to get the center console out and do the uglier areas.

Help please I am really confused by Sundown's X 15 single box design that they offer on the their website. It says it recommends 4.25 Cubic feet for the X 15 yet the box they show to build to me seems as though it is much smaller than that after displacement. The box that it is currently in won't fit in my trunk. It measures 16.5" tall X 22" Deep X 33" wide. I need to do a cardboard mock up to see what will fit in my trunk. I would like to have it as close to recommended spec as possible. What I don't understand is that Sundown says it needs 4.25 cubic feet, which I have to assume means net not gross, yet the box design they offer for download I calculated to roughly 4.195 Cubic feet gross. This doesn't make any sense, any input would be greatly appreciated. Attached is a picture of the box sundown recommends. This will be my first box build ever so I really want to do it right. I have the carpentry knowledge I just have never built a box before. Ideally I would like it to be tuned to 38hz, the X series is already a low note crusher and I was told that If I tuned it higher it would give it more bandwith. Thanks for any feedback. I can get the max dimensions of a box that will fit later on tonight if anyone would be willing to help me out a little bit with the design.

So the build is finally decided, just haven't figured out which way to point them the box is as stated: 6 ft3 with a 4 inch wide slit port tuned to 29hz Port and sub direction? Or would you go with a different style of box for a 15 inch SA Sundown Audio running on a bd1000.1? Please help! Thanks so much.

hello all....im upgrading my substage this spring...and would like to know if I will need two runs of 1/0 for my sub amp (SAZ2500dV2 pushing two X10s in a 1 ohm load) I know I would need double 1/0 inputs. for electrical, I have Singer 200 amp alternator, one D3400 under the hood, and one D3400 in the trunk. I have another amp running the highs and mids, but its running 60x4 in a 4 ohm load...I don't think that is of much concern, just getting a feeling from folks if 2 runs is overkill, or preferable for the low end. thanks in advance guys!

Hello all! I'm new here to the forums and I thought I'd start by posting a build thread for first build. I've been looking into audio for a very long time, but recently started looking specifically into car audio about four years ago. I built my very first box a year ago (April, 2016) after ordering my subs. Since then, I worked and saved up for my amp, batteries, and wire (other miscellaneous stuff as well) which I recently purchased this winter. I got everything in the mail a few months ago and only recently installed everything. It's been a very long work in progress (I replaced my door speakers and fabricated my A-pillars three years ago and have been saving up since then) and will continue to be improved, but I'm happy to finally share it with you all! Here are some pictures in chronological order of everything as it has come together (sorry for the poor iPhone quality): April of 2015 (As you can see, this was my very first box build. It's not very pretty and there was lots of sanding to do to make all the edges meet flush) The subs A couple of months later (February 2016) and I stripped the vehicle down to the bare interior so that I could run the wire and RCA's through the car (for my daily, I didn't want to run the wire underneath the vehicle. Looking back on how tough it was to run three runs of 1/0 AWG through the firewall, if I did it again I'd do it differently!) Interior reinstalled Under the hood Progress Heatshrunk! Batteries, bussbars, box, subs, and most of the power wire installed The (temporary) wiring setup About a year of work, and that's where I'm at! I've done a little more work to tidy things up, but for the most part, I've got everything done and ready for the amplifier to be dropped-in when it arrives. Speaking of... I ordered my BC5500 in December, but shortly after they went out of stock and you know how Crescendo restocks go... Four months later, and here I am anxiously waiting for my amp to restock and show up in the mail. In the meantime, I'm working on rebuilding my box and the floor underneath it. I'm currently very unhappy with the way the Herculiner turned out. It was my first time using the product so my lack of experience made it clump and lay unevenly over the entire box. Additionally, the box itself was my first, unexperienced build, and I've learned a lot about boxes and building them since them. The box has a 32hz tuning and I'd like to drop it lower to 30/28, so I'm going to be doing interchangeable ports (I realize that I will be changing the 3.5 cubic airspace by adjusting the port volume, but the subs will not be in a space that is any less than their minimum recommended with the largest port). I'll also be replacing the OEM trunk floor (about a 1/4" thick) with 1/2" MDF. It'll be much stronger and hold up to the flex and weight a lot better. I'm also unhappy with the battery tray and amp rack that I made (very temporary 1/4" angle iron rectangle mounted to the floor and 1/4" wood as the amp rack) so I'll be replacing those in a much more permanent fashion (I've got a few ideas in mind). In the meantime, let me know what you guys think!

Hey everyone, i'm new to this forum and to audio. I have a 95 civic ex, running a Hifonics 1500D to a Sundown Sa-12 D4 in a box i built myself to 35hz, The amp is at 2 ohms at 1,000w. I get a little fading in lights. I want to get a second Sa-12 d4 and run it at 1 ohm. is my car going to be able to handle 1ohm? if not what about with the Big three? i dont have much money to throw around, i would think about getting a bigger alternator if anyone has recommendations. Thanks in advance.

Hello everybody, this is going to be my first big banging system (hopefully) I just purchased a 2014 f150 supercrew, and want to but two sa-10-zv4's in a sealed box from Supercrewsound.com. I see everywhere on the internet where people are saying to use a ported box but since i don't have the space in the truck I believe this is the route i need to go. I will have them on a SAZ-3500d-v2 wired down to 1 ohm so the amp will produce "the full 3500w" ( probably not) but That would leave 1750rms to each which is what Sundown recommends. Which brings me to my box delema.. Here are the specs of the box. Air Space = 1.10 cubic foot Per Sub Mounting Depth = 7 1/2" (10" sub) Hole cutout for 10" Sub = 9 1/8" I also saw on the sundown website (and others) that they recommend 1ft^3 per each sub which this box exceeds a small amount. Do ya'll think this would be do-able without it being a gigantic waste of money not giving the woofers EXACTLY what they want (huge ported box, tuned)? All information is appreciated. I will be adding ateleast two good batteries, and a 300a alternator to power these bad boys along with the big three. I know thesee woofers are made to get LOUD and that's exactly what I want, I've had two rockford fosgate 12"s on 300watt rms in a few different vehicles, and have some 3 12" jl's in my car now on 600watts rms. I think i'm ready for some real deal woofers! Thank you if you can help. Here are some links to the woofer box, subs, and amp. http://www.supercrewsound.com/09F150SCrewUTSdualdeep.html (box) http://www.sundownaudio.com/index.php/products/amplifiers/item/saz-3500d-v2.html (amp) http://www.sundownaudio.com/index.php/products/subwoofers/item/z-v-4-series.html (subs) Thanks, Tyler

What's up gentlemen! Here's a couple of boxes I've been working on for a friend at work while my build has been on hold. They both went under the back seat of a 2012 F150. Here we go. Early stages on Sketchup. It came out to 1.67 cubes after displacements and tuned to 37Hz. Port area was 4" by 4.5" and 17" long IIRC. Pieces cut out.

I have two Sundown Audio SD-2 10D4s in a small sealed 0.6cuft per sub enclosure under the rear seat of my F150. I am running them 4 Ohm mono on an old school RF Punch 800aii amp. I just purchased a new Ford Fusion (daily driver w/better gas mileage than the F150) and want to build a dual ported enclosure for the Sundowns since I now have the room. I designed a ported net 1cuft per sub enclosure. Using a 33Htz tuning frequency with a 2.5" diameter port, I've calculated the port length to be ~10.32". A slotted port for the same tuning at 1" wide 11" high, I calculated a length of ~23.98". Now to my question, I found this Ground Shaker enclosure on Sonicelectronix for $79.95 free shipping! Materials for my box alone are nearly this price. It's an ideal volume, 1.10cuft per sub, the Sundowns displace 0.08cuft for a 1.02cuft net (SA recommends 1.0cuft for ported). The box is made from 11/16" mdf. I can't find the slotted port dimensions for this box. From the picture I approximated it's dimension to be 1" wide 11" high and 20-21" long. The box's depth is 17.5" and the port should be nearly 1 & 11/16" shy of that, (I'll use 16" to be easy). Then the port turns 90 degrees and continues what looks to be 4". Together that yields between 20" & 21" (adding 11/16" for thickness of the 90 degree turn). For a 1.02cuft box, I calculate a 1" x 11" slotted port 20.5" long would be tuned to ~35Htz. I just want some opinions, and my calculations checked. Thanks!

So I have recently purchased two SA 12's dual 2 ohm, and a Hifonics BRZ 2400.1d. First questions. How long should I break these in for? I plan on running at 2 ohm obviously to give it that extra power these subs crave. I currently have a Kicker box approximately 4.4 cubes tuned at 42 hrz. Now I know this box is far from a 'good' enclosure for this setup so I was wondering if anyone has any suggestions for a box build or prefabbed box sizes. I would like to know if I should get a box with a side port or a front port firing to the rear of the vehicle. Lastly, I have yet to get a second battery for the trunk (going in a cavalier) and would like to know what size battery I should get. Any ideas, suggestions, opinion, etc. is extremely appreciated! Thanks guys. I know SMD forums will get me the most accurate and reliable information available online.

I had this vision of getting another 1962 Chevy Biscayne Wagon to build to pull my white Wagon Bis-Kwik to out of state show's. Well I searched for about a year or so and one actually found me! My good buddy from VA had this Wagon for several years and was showing it, It was hooked up at one time, but he got a 62 SS Impala that he started doing and pulled a bunch of parts off the Wagon to go in it. His Wagon sit for over 3 years and he contacted me the other night and told me he was tired of it sitting and going down hill and he wanted me to buy it cause he knew I would get it back on the road. I JUMPED all over it and took a road trip and got it! Now that's it's home I have already gave it a name "Pig-Pen" This is the plans with it, I want to do a Cummin's Turbo 6BT swap in it, put it back on air ride and a nice set of rim's. For system since it already has front bucket seats in it and a console I will build my own console system. Keeping this one a little simple since it will be my hauler. I am going Friday to Sundown Audio HQ to pick up some of my equipment. I will keep yall uptodate on this little build!

So the last post got locked for the choice of words, I didn't intend the post to be a vs post, so I just have to reword the post. What would your favorite budget 15 Sub/Amp combo? (SPL would be nice with them as well)

I have done some searching and there seems to be some debate. I haven't seen a thread about this topic for this particular sub so I figure I would just ask. Sub up port back? Sub up port up? Sub back port back? etc. etc. This is my daily driver and I listen to everything from rap and dubstep to metal at times. I plan to demo it and maybe compete at local shows this summer. Amp will be 3500 of some kind, not sure which route I am going yet. Singer Alt is getting ordered this week as well so electrical should be solid. I figured the easiest way to get her home was to belt her in. This is by far, the largest sub I have ever owned. I have been grinning like a teenager on prom night since I got home.

I'm planning on upgrading from my single Sa12- to 1 15" SSA Xcon. Want go musical (sub) and get loud (4th order box) while sounding clean and crisp! I might be going with and American Bass Elite 1800.1 or SoundQubed Q1 2200D I'm not looking for exact dimensions yet. just looking for what woks and what is going to sound Musical My suggestion 1:.75 Ratio look --> PORT 4 ft^3 tuned 45hz Sealed 3 ft^3 both boxes are made by manufacturer specs, disregard displacement it will be calculated later on. Is this build efficient? Am i going about this right?

Okay everyone, Here is the beginning of a build that I have put more thought, blood, sweat, tears, and effort into than any other build I have ever done! I am always open for Constructive Criticism in any of my builds! I know most of you like to see goals/equipment lists in the first post. Goals: NOT cutting any corners on anything or "rigging" anything up Build something that can promote my dream of becoming an audio enthusiast and shop owner Build something with mids and highs that can keep up with the bass (Even though I never build anything geared towards numbers,) achieve 150+db on either the kick or windshield on music. Build an enclosure for the subs that can be played at full tilt, and rest a penny on the top of it and have it not move at all Expand my knowledge of fabrication and learn as much as I can. Edit: (forgot to add this) Not have ANY interior or exterior rattles at all. Equipment: 2011 Ford F150 4 door full cab 2 wheel drive with 6 inch lift kit, 20 inch rims, 35 inch tires, and a nice train horn 2 Rockford Fosgate Punch Pro tweeters 4 Rockford Fosgate Punch Pro 6.5 mids 4 Rockford Fosgate Punch Pro 8 mids 2 Crescendo Audio Symphony 800/4s 1 Sundown Audio NS-1 6 Sundown Audio SA 12s Loads of Sky High and Audio Technix 16 gauge, 12 gauge, 4 gauge, 1/0 gauge, and 2/0 gauge wire 3 Powersafe 190 ah batteries Singer 320 amp alternator Custom subwoofer enclosure Custom door pods Custom Battery rack Custom Amp rack Custom Ipad dash Custom center console Custom rear wall trim Custom trim around sub enclosure Clarion 7 band EQ Bluetooth Reciever ^there is probably a good amount that I dont remember lol Pictures to follow There are Soo many people to thank for helping bring this build to life, even the smallest bits of advice can help so much!

For now, while I sit and wait, I am going to post my current set up just to show you all some of the work I have done so far. I don't have all the pictures since some things were done a little while ago such as, deadening, changing my door speakers, wiring etc. but I will eventually tear some things off and show you how I installed everything. Here it is.... Here is what my car looked like brand new.. Tint is 30% and hubcaps now plasti-dipped.. De-badged and replaced the stock antenna with a "shorty."
