  1. Hello everyone, I am in major need of understanding port measurements for slot ports with 3 common walls. I have built a few amazing sounding boxes in past and always guessed port length and got lucky considering I don't know anything about the math used to figure out ports. I have a Sundown SA 12d2 on a Sundown 1100.5 it is @1ohm and currently in a prefab box that sounds horrible. I am wanting to build a box between 2-2.5sqft as I've heard these subs actually need bigger than recommended. I'd like to tune between 27-33hz and require a solid bottom note and a flat curve that doesn't drop till well in the 100hz range. Width has to be 35" max and no less than 34" heigth max of 15" and max depth 16" Sub and port both face rear of trunk. I have both BassBox 6 Pro and Torres Tuning Calculator. Any help figuring out a box that hits the deep lows and has a strong full range will be considered. Also help understanding how to get the port measured and cut correctly. Any help understanding port ratio greatly appreciated as BassBox Pro always seems to give better designs with small width ports where as Torres I find bigger ports do better. Thank you for any and all help to tho that post suggestions!
  2. hey, new to the site. just looking to see if anyone has any recommendations for a sub i can use with my amp and box. my box is a trunk mounted forward facing 12 inch sealed box with .94 cubic feet and a depth of 7 or 7.5 inches. i forgot exactly, i built it 8 years ago. my amp is a 2004 rockford fosgate 1500bd. the amp is rated 750 watts rms @4 ohms @ 14.4 volts or 1500 watts rms @2 ohms @ 14.4 volts. im considering keeping it at 4 ohms because of my electrical system and my other amp and accessories. im running a stock 80 amp alternator with 2 optima yellow tops and 0 gauge jl audio power cables. im also running a 2002 us acoustic amp to my polk audio mobile monitor 6.5 components for my front sound stage. the head unit is a Pioneer DEH-80PRS. i prefer SQ but would like a louder deeper bass. i have previously had the last generation 2016 alpine type r (1000w rms) but it only lasted a year and a half but did sound good for a while. also had a 2002 earthquake dbx12d (400w rms) wired @8 ohms. im looking for something that will produce better lows then the type r while still keeping the box in the forward position. im considering the SA12 D2 or the dc audio level 3 but im also tempted to get the level 4 or fi ssd neo 12. also considered the image dynamics id12 but i hear their somewhat delicate compared to my other choices. if anyone has any suggestions or any experience with the subs i listed in a sealed box please let me know. thanks.
  3. Can someone help me out with this I’ve been reading for days and can’t find the answer I’m looking for. I bought to sa12’s I’m having a box built by high output enclosures I just can’t figure out if I want to to go 2.25 cubes per sub or 2.5 per sub net. I know I want subs up port back. It’s going in a 4 door Jeep Wrangler. I’m pushing them with scv2000 at 1ohm. I’ve done big 3 , 240 amp alternator , and xsd3400 battery. I’d highly appreciate it if anyone who knows what they’re doing can give me some advice on what they think. Thank you.
  4. Can anyone tell me the freq. that the SA-12 single box design... is? According to my calculations, it is around 27hz, but I'm using a port calc, and I'm not even close to being a port expert. Thanks in advance!
  5. Hello, Im from Belgium so sorry for my bad English Im new in box making etc, bud i tried something out on sketch up using torres box calculator. Next week i will buy 2 Sundown SA 12's and i'll be running them on a Massive Audio N3 (1400w rms). I would like to have a box tuned to 30Hz ( i love the very lows ) , subs facing up, port facing up, box same height as my backseats so if i look in my mirror i can see the subs( i hope you ounderstand what i mean) I made a box design on sketchup and i wonna hear what you think about it and what should be changed about it. Here in belgium we work with cm's/mm's and liters, so for the torres box calculator i needed to add 0.2mm on each site of the box because on torres i can only use 19mm MDF and here in belgium we have 18mm MDF.. the only thing that could be wrong is the volume that the subs have, its 1.3783ft³/sub NET volume.. :s here are screen shots from sketchup and torres.. the torres screenshot are the specs for 1 chamber plz help me?
  6. Hey guys, this is my first ever post on this form. scratch that, any form ever! so take it easy on me. Im in seach of adivce or thoughts or comments on what to do with my next system setup. Im currently running 2 American Bass XFL 12's dual 4's off of a hifonics brz2400d (not my top choice but i was on a budget and hey i can't lie, it does the job) wired at 1 ohm, with a kinetik khc 2400 in the trunk to help things run smoothly. Now, i have a stupid pre fab box, and am building a new one sometime in the next couple of weeks, already have the diagram drawn up. My question to you all is i plan on switching to a Sundown SAZ2500D amp, for obvious reasons, the thing is awesome. But I kinda want to sell the XFLs and try out 2 SA12's? what is yalls input? I know the XFLs have more power but that's not a problem becausae the sa12's can take every part of 2500 rms. I just feel as if the SA12's are a better quality sounding sub from what i've heard, and produce better numbers. All thoughts, Comments, Concerns, Stories, and funny jokes are encouraged! thanks ahead guys!

  8. Hi guys, I'm new to the forum and I wanted to get some suggestions to add more bass to my set up. I currently have a 2013 Chevy Camaro with the following gear: Stock Head unit Audio Control Processor Alpine 4.100 4ch Amplifier Alpine PDXM12 Mono Amplifier rated at 1200 to 1400 RMS Polk RM component for highs Kicker L7(2008 Model) in a sealed 1.5 cubic enclosure I've heard that Kickers are loud but not good for SQL, but I've never had a frame of comparison and in my opinion it sounds good. I'm looking to do an upgrade the subwoofer to add more bass and if I follow what I've been told any of the brands I'm looking for will have better SQL. An custom enclosure will be built for the sub I choose but I have at mat 1.5 cubic feet sealed to work with (If it can be smaller that a plus). I would like some suggestions on which set up will sound louder and have better SQL when compared to the L-7. I listen mostly to rock music and in some occassion R&B. I want to buy the subwoofer new and I have a $550 budget. The set up can be dual sub or single sub and I want to keep the airspace as low as possible (1.5cubic or less. I also want a good name brand with good customer support..... Thanks in advance for your input......
  9. my friend found a sa15 for sale brand new on CL put i just found 2 sa12s for like 20 bucks more.. and idk what he should get.. he wants to be really loud but he probably wont want to pay the money for a amp to power 2 sa12s at least not a good one, so my question is what should he buy and why?

    Any Final Suggestions??

    After plenty of research, i came down to my final two options i'm considering: 1.) 1 ssa icon 15 w/ aq 1200d 2.) 2 sa12s w/ soundstream 1600d I'm going for more sq than spl since i have a small car (05' corolla) and i really appreciate great sounding bass. Just to answer the basic questions, i like bass heavy music, both choices would be ported in a proper custom enclosure (which i will build) and i really wanna use less power since i dont wanna invest too much in my electrical system. Thx a lot for any input and u guys really helped

    Budget System Question

    So i've read many threads asking a similar question on a variety of sites but i never saw a good "educated" response which didn't sound like it was written by a 15 year old. Just to clear things up, is there a negative to going with 1 "good" 15" sub, instead of 2 "crappier" 12"s?? I don't have the power, budget or cabin room to run 2 sa12s so im deciding between 1 sa15 or 2 e12s. It's a really hard decision to make, due to the many myths u hear about 15" subs, so any help will be greatly appreciated! Also just to support my decision, does anyone here think that 2 sa12s on 1700 watts is just too overkill for a corolla 15"??

    2 sa12 enclosure

    I need help on the port tuning the box will be going through the arm rest so port can be too big. Read pic The box so far
  16. How big of a hole should I cut to invert a sa12 with causing surround tear.
  17. I like any people have a car with rear seats that don't fold down. Does anyone have any advice or can anyone share what they have done to make the bass louder in the cab of their car?
  18. Would a Deka 9a31 + xs d1200 + 1 under the hood battery with a stock alt be enough to power a True 1800rms amp???
  19. So the past couple of days I've been re building my set up. I got another sa12 so I had to make a new box so decided to redo everything. Im really bad at taking pictures when I work and always forget so I didn't get that many. Now I don't have anything crazy so i don't expect people saying my set up sucks blablabla because i know its not amazing. I'm just here to share my shit. So here are some pics. I'll get some more tomorrow once i finish the front beauty panel. first off, heres the car. Its a 98 oldsmobile Aurora. Shes a sleeper. Got a 4.0 32 valve northstar V8 under the hood. Heres the box I made for the 2 sa12's. Its about 4.8 cubic feet tuned to 30 hz. I like the lows lol (nothing is glued together in this picture) Painted the port white. You'll see why later I had to build the box in my trunk because my trunk opening is really small and the box is really big haha. 5 inch wide port Just decided I'd snap a shot of the Alpine Type R 6x9's while I was under there Heres the box pretty much all together. You can't see in the picture but I have supports in the middle from front to back and top to bottom. The amps on top..I took a piece of 1/4'' smoked plexi glass and put sliding rails on the side then mounted it to the box and then mounted the amps to that so I can slide the amps in and out when i need to access them or show them off. Both subs in! Heres the amp rack slid out a little bit. they slide out more but i didn't have anything screwed down at this point so didn't want the amps falling off. Night shot And this is the reason I painted the port white. I'll upload more pictures tomorrow after I finish the beauty panel. I'm gonna wrap it in black vinyl. Hopefully will come out good. Let me know what you guys think of my build! I know its not "amazing" but im happy with it for now. Hopefully getting an aq2200 soon to replace the hifonics.
  20. I have two sa12s on a saz1500 but I only have an xs d1200 in my trunk everything stock under the hood! My system dosen't seem very loud to me but my voltage commonly drops to 11.5, if I have a higher voltage like 13.5 on full tilt will my subs be louder. So my main question is does low voltage effect the output of watts on a amp?
  21. So I put something in my trunk and it hit my SA12 while it was playing and fucked up the surround, its not broken, still plays, but ik after a little while it will eventually break and sound like shit. Do I need a whole new recone kit now or can I just put some speaker glue on it?
  22. This is my first box build, It's for 2 Sundown SA12's. I wanted to use Torres but it wouldn't let me download it so I used RE box calculator. Do you guys think these subs will sound good in this? I've been working on this box for a couple days and am gonna wrap it in black vinyl tomorrow. Let me know what you think please!
