  1. I have a 350 amp apex alternator, a front battery delete with sky-high terminals, and a 40ah lithium battery in the back next to the amp. Im running dual 1/0 for my big 3 and from my battery delete terminals to my lithium battery in the back. My question is what size fuse do I use for my alternator positive to the battery delete terminal? My next question is What size fuse do I use from my battery delete terminal to the 40ah lithium battery in the back? (Keep in mind my big3 which also includes alt positive to battery terminal positive is 2 runs of 1/0. My battery delete terminal to 40ah lithium is also two runs of 1/0, its about 25 feet from battery delete terminal to battery.) Thanks guys! BTW ALL FUSES ARE ANL
  2. i need help deleting vehicles from my garage as i no longer have them. have been trying to figure out how and i just cant figure it out. can anyone help? please?
  3. so im getting ready to do a small budget build in my accord. nothing too crazy just a pair of the new skar audio ix 8's d2 on a jbl cs300.1 amplifier with all execution audio zero gauge plus kinetik powercell and sony 4 channel with pioneer coaxils and sony receiver. i plan on making the box around 1.8 cubes after speaker displacement. i plan on putting in an aeroport. my question is what size port should i get for my pair of 8's? i read a thread on here about ports but i just dont understand everything fully. i was thinking a 4 inch port would be enough for both but im not sure. any help is appreciated. also wondering what i should tune it at as ive never used 8's before and didnt know if tuning them in the mid 30's would sound good or not. i checked the skar website but they dont list box or tuning specs.
  4. Hello, im from Belgium so sorry for my bad english, i hope you will understand me. im planning on buying 2 Sundown SA 12's and im going to run them on a Massive Audio N3 amp. and i need your help and thoughts, i know a little of how to calculate a box for the subs bud im not not that good in it. 1, i drive a Ford Fiesta mk6.5 and my car runs on 14.3/14.4V 2, Does the 12's going to be too big for my car? i want A LOT OF BASS, i love the very lows like decaf songs etc... 3, i will do the big 3 upgrade to my car bud i would love to keep the stock alt, is that possible? 4, will someone plz design a box for me for the 2 12's? i was thinking about a 30Hz tuning, subs facing up, and the port in the middle of the subs (also facing up). or would it be better to face the port to the back? my trunk dimension i can use are: 45cm height, 97cm wide, 45cm deep. I really hope you will help me out with this, i dont know that much of subs/amps/box making, i ony installed some entry lvl sub/amps an made 1 box for a kicker L7 12" so i dont have that much experiance. and if you agree to help me out with this, will you plz design a box in centimeters / millimeters with 18mm MDF? because here in belgium we only got 18 or 21 millimeter MDF. (not 19mm like 3/4inch and with torres calculator you only can use 19mm MDF) You don't know how much i would appreciate it if you would help me... Plz let me know something... grtz
  5. Alright guys I have an issue, I'm just not sure exactly where or what. Ill try to include as many details as possible. My current set up: 2007 Jeep Grand Cherokee with "premium" speakers and amp. Details on that here Pioneer AVH-5500BHS bypassed Rockford Fosgate T1500.1BD 1 15" Fi BL @ 1Ohm 4GA power wire So to my issue. I've had this amp for about a year and a half now. About 6 months ago i noticed that occasionally I would hear a very high pitched humming and my amp wouldn't come on. This always happened when I started my car, i assumed that it was because the inside of my Jeep was hot so it went into protective mode. Yesterday it happened again, drove it home, left about an hour later (parked in shade) and it came right back on. This morning I was driving to work and it was working fine and suddenly my amp died. Got to work and checked the fuse, it was blown. I've never blown a fuse until today. Thought it was a fluke and put another in at lunch, it was hot inside my Jeep again (all black is HELL) and it did the humming so let it sit. about 30 mins later it came on when i stared my Jeep. Started to listen to a song and the moment I turned it up I blew another damn fuse! 2 in one day, what the hell! I come home disconnect my amp, check all of my wiring which i believe is good. Reconnect all of it, I have the power light come on the amp.... but no bass. Turn it off and restart my Jeep, and i get the humming, amp isn't on. I learned that the humming is coming from the 2 front speakers on the dash not the amp. Took out the fuse and put it back in, I went to check the power (not running but just power) and i have the light but once again no bass so i turn the Jeep on and now I'm here. Amp not working and humming constantly coming front 2 dash speakers. Does anyone have any ideas of what this could be? Bad wiring somewhere? Faulty factory amp interfering? Bad RF amp? I'm at a loss any help will be greatly appreciated.
  6. I just ordered two sundown audio SA 15 d4 subs. I have a CT sounds 2500.1 that i plan on powering them with. I have a 2001 Oldsmobile alero 4 door, I took out my back seats and plan on puting a box back there since theres no room in the trunk. The amps are going in the trunk along with the battery. I have been doing research trying to find some box designs online but could only find 2 box designs that are slightly to big to fit. So if anybody could help me with a box design i would appreciate it alot. My max dimensions for my back seat are 26 height, 21 depth, 34 width . recommendations are 3-4 cubes 35hz. i would like the box to be on the smaller side but not to small maybe like 3.5 cubes to each sub or 3.2.
  7. I am thinking about putting 1 12" Sundown ZV4 12" REV 2 in the trunk of my bmw 530i. Most likely going to face the box towards the seats since my seats fold all the way down. I will most likely get a 220 amp H/O alt from exsessive amperage, its about the biggest I could find from a notable company (singer, mechman, dc power, or anyone else that might be named has already been contacted and they wont make one for my car). I will probably have 2 extra batts (xs power d3100s probably) and a stock replacement, big 3 and a couple runs of 0 guage ran. My questions are, What size amp can I get away with here? I was hoping to go with a sundown SCV-3000d just to keep it in the sundown family. Would this be too much for a single ZV4 12? Reccomendations welcome... Would a straight back facing box or maybe a rear deck blowthrough get me better numbers? Would the elictrical I have be enough to keep this amp happy? Please help me out, all opinions are welcome. Any opinions on possible numbers? Any help is greatly appreciated. (No im not a "sundown fanboy" I actually just had a 15" FI BTL N2 on a BC3500d in my last vehicle, I just dont have the room for it in this one and wanted to try something new)
  8. Hi, I am new here and am currently installing a new system into my car. I just wanted to ask if it is ok to screw a amp directly into the metal chassis of the car (I know that there is not a gas tank behind it). This is the same part that the amp is grounded to. I just wanted to ask because I got a amp that once would not come out of protection unless it was not screwed into the car. The amp I am working with is a P400x4 running at 2 ohms. Thanks! -Josh
  9. Is There Still A Show Going On This Weekend Even Though Its Going To Rain Because I Dont Want To Drive 5 Hours For Nothing Its My Very First 1 Im Really Looking Foward To It
  10. I have recently gotten a sundown audio zv4 15" d2. I'm looking for an amp that will power it along with a secondary battery and then the best way to build a box to go into a Toyota Corolla trunk Whether it's sub port back, sub back port back etc What are some great amp brands that will rms 2000-3500 watts and sustain play It can be bang for buck or bigger price range Also would a aero port be better or regular port space wise and effiecency wise Thank you very much
  11. okay i just bought the dd1 a few days ago and i had couple quick questions. When tunning the amp should i use cd test track or downloaded versions on phone via bluetooth. honestly i dont listen to cds im either pluged into aux usb or bluetooth does that mean i should tune my amps while playing the track on my phone using aux usb or bluetooth or does it not matter its all them same??? reason i ask is because aux usb and bluetooth are considerably louder than cd i have pioneer 4800 bhs
  12. Hey guys i'm currently working on designing a 4th order bandpass for my two rockford fosgate 12" p3 d4's and i'm stuck on square or aero port and if the one or other port area and length. i tried using this calculator to help me figure it out but yeah that kinda failed where i got the result for port area the size of the car it self so i really need som help with this. the box it self right now is a triple chamber with the sealed chambers at 1,17 ft3 for each sub and the vented section 2.14 ft3 net (i'm gonna invert the woofers) with a tuning of 46hz and the roll off is -3db at 27 hz close to the fz of the woofers and im going for a more sq box daily box then spl and i thought a 4th order would be good for the woofers. I'm considering using 3 or for 6" aero ports but the depth of the box isn't sufficient enough. or a square port in the middle but i dont really know what size it should be or how long. every bit of help is appreciated. cheers from another bass head from sweden! - Hampus

  14. So I just got this amp in a trade, I know it needed some repair. Not sure what kind of project I took on, I know how to read the part numbers on the board. But the part missing doesn't have a part number on it, I assume it was on the actual part that wasn't included. Can anyone tell me what the part is or the part number? I can help out with any model number or anything, but just off my mind is all I remember about it at the moment. Here's some pictures of what the board looks like with the piece and without. ]
  15. Hey errrrrbody. I am very close to locally purchasing a ZX350.4 for my first mids & highs amp for a great price in my city up here in Canada. the reason the deal is good is because the amp is supposedly not working properly. What the seller has said in his ad, and as well as through text messages is that it "Works great but won't turn off. The technician said the FAT must have been fried (whatever that means) other than that it still works." and.. "it turns on the moment you hook it up to the battery but it won't shut off even with the car turned off. It was bought brand new but I just shorted it when I installed it." Has anyone ever dealt with a problem like this? Is it repairable? I personal had my bass amp repaired at some circuit board repair company in town so that may be an option for me as well. Please advise!!!
  16. I've got a Orion HCCA 12.2 in a ported box and I'm in need of an amp but unsure which brand or wattage I should get. My sub is rated for 2000 rms 4000 max power. I plan to wire it down to 1 ohm so it needs to be 1 ohm stable. Suggestions? Help? Thanx
  17. Hi I'm planning on building my own box for a ROCKFORD FOSGATE T2. I was wondering if someone could help me with a diagram with the dimensions, because I'm not sure how to incorporate a port into the box and where to put it for the best sound. I wanted it ported and it has to be small enough to fit in a sedans trunk. Any help would be much appreciated. Thanks
  18. I recently screwed myself out of a deal and need a new amp. I've been looking around and came across the Sundown SAZ-2500D. (I have an Orion HCCA 12). I just wanted to know what the forum thought about this amp on this sub. I bought a nice sub and I don't want a cheap amp that's why I choose Sundown for an amp, I plan to do this the right way.
  19. Whats up everyone, i'm new here and I'm really getting into car audio. Right now I have a 2004 Chevy Silverado that I threw 2 shallow P3 12's in. I really want something louder. I'm not quite ready to do a blow through, so I want my first build to be 4 Sundown SA-8's underneath the rear seat, facing the front. I want two 4" ports, one on each side. I'm extremely new to box building, but I learn very fast. I have a few questions, and I would also really appreciate some pointers & tips. Question #1: Since I want 4 subs with a port on each side of the box, am I going to need to put a center divider in the center of the box, so that I create two chambers, each with two subs and a 4" port? Question #2: The SA-8's recommended box volume is .5-.75 cu. ft. so should I simply take .5 and times it by four, giving me a 2 cu. ft. box volume for the 4 subs? That's all the questions I can think of...for now. Any tips or other help is GREATLY appreciated!! Thanks, Mike
  20. I've got a 2000 Nissan Pathfinder and right now I'm on my second system, running a Power Acoustik LT1440/2 bridged for a Kicker L7 in a Kicker custom box that they discontinued with the metal grill on it all on stock electrical with a new head unit, 2011 Pioneer DEH-6350SD. The box is pretty big, but im looking to upgrade and found Audio Queue. i live in an area where the only car audio store i know of reps Z-Stat and thats really about it. I tend to stay away from most of their other products and only have a pair Z-Stat woofers in my front doors because i blew my bose up there before i knew much about car audio. Found what ive got now online. Wondering if i were to buy two AQ SDC2.5 12's and throw them in a generic ported box with an MB Quart ONX 1.1500D, if it would be worth the change, or if i would even notice the difference. Should i find a custom box? ported or bandpass?
  21. I basically just want to know if this design will work for my sub, my only concern is the port area, i know 14in of port per cube foot is ok, but it only has 8.5 in of port area, so comment if its good, or bad. Thanks. Sundown SA-8 D4 v.1 Wired at 2 ohms getting about 550 rms 10x23x12 box dimentions 8.5x1x30 port dimentions 34.29 Hz .64 cubes after sub and port displacement 8.50 inch port area 13.28 inches of port area per foot
  22. So I think this might be a little noobish but I still havent done the big 3, I know I know, It should have been done a long time ago. Anyway, Im going to do it next week but I am extremely nervous about it for some reason. Does anyone have any pointers for me? and Exactly what I need to do it. I know 1/0 gauge ofc wire but what else? Has anyone thats done it on a 2002 ford explorer know the best place for the ground? ahhh, help! thanks guys.
  23. I've decided on buying a Fi Q 15, I just need help on finding an amp that would be best suited for it. I have a Treo amp that pushes 1000 watts that i'll use to break it in.
  24. I am currently running two JL 12W3's and am looking to upgrade to a single, better sub. I'm having a hard time deciding between the two in the title. Please help. I listen to a lot of metal and rap. So i need quality and great response time for double bass and whopping bass for 808's and rap.
  25. i have 4 mofo 15s, i would like to pull some decent numbers and keep it an every day driver. the box will be 22.86 cubic ft, 220 in. port area, tuned to 35 hz. all will be double thick 3/4 in mdf, with bolt bracing. subs and port up port. port by back window or up front? will it work correctly with the subs i have? love to hear your input. new to this big of a set up.
