Ok well I have a roll of rammat (60 sq feet) and want to do my trunk as well as the two front doors. I know I will have to use it sparingly so I wanted to get some suggestions on where in the trunk I should put it. Here are some pics of my trunk stripped down. Also should I do where the spare tire goes or should I just put it around that? Entire trunk: Lid: Right side: Left side:

I went to a little car showoff / competition yesterday. This was in no way an actual 'organized' competition. Classes were setup as single subwoofer / double subwoofers / Three + subwoofers. After going through all the contestants, they handed out the trophies and prizes. First up was single subwoofer, my class! They call third place, at a 136.9db (I think i got this shit in the bag for 2nd place and my buddy would get 1st place). Then, they call 2nd place.. NOT me 142.1db. Finally they call my buddy for first place at 148.7db. So. I go up to the sheet and check my name.. I got 144.7db! They skipped my name i guess.. Anyways i told the instructor of the competit…

My 10'' bl came in today and I couldn't wait to hear how my box turned out. Here's a picture of what it looks like: The box is roughly 1.15@33hz with a 3'' aeroport. But when the lower bass notes (in rap) were played, there was a very distinct "slapping" noise coming from inside the port to the beat of the bass. Is this considered port noise? Or could it be that one of the wires inside the enclosure is too long and is hitting the side of the box/sub? Or could it be a leak somewhere? It is very noticeable, especially because it is behind the seats in a reg cab pickup and the port is firing up right behind your head.

A year or two ago I had a box made by the local shop, I asked them to build it the specs of IA for the LI 15 but I'm doubtful they did so? The port looked and always seemed too small, it doesn't have any L shap as far as the port goes its just straight back and seems too slim...how would I measure the port to see the tuning and determine the total cubic feet? Also by first glance, does anyone think something is wrong here with the port....when I see most other builds by specs they all look a lot bigger...shady shops, only in it for the money smh.. I'll upload some more pictures tomorrow for a better look...

Hey guys I've been searching around trying to find the answer to this question with no luck. I've seen plenty of topics/build logs where subs are being inverted but no real how-to on the wire aspect which brings me to my question. Do I have to do anything special to the wiring if I want to invert my subs? I slightly remember reading something about needing to change the polarity. Is this true? If so, is there a setting on the amp or do I just switch the neg/pos wires on the amp? This would be the first time I'm trying this. The reason I want to do it is the baskets on my Nightshades are the oldschool sexy chrome and my box is a little on the small side. I hear running the…

What brand would you reccomend.

Hello everyone, Its been several years since I was in the car audio scene. I am interested in getting my sub up an running again in a cost effective way. Last I was involved, team PSI was doing a lot of customizing subs, many many people were running Sundowns, and Audioque, DD, and FI. I had an 18" Treo Engineering SSX which was rebuilt be PSI as a dual flatwound alum VC. I was running an Autotek MM3000.1 at .5 ohms tuned to 33Hz. Daily I was doing about 148+ db. I saved this sub for the last 5-6 years because I loved it so much and swore to myself I would use it again some day. Team DOA was killin it in the Chicagoland competitions, especiall…

Well, I'm pretty much excited right now. Just ordered my new BTL N2 18 a few minutes ago. Just wondering if you guys think an aq2200 will do the trick of supplying this beast with the power it needs, and if not, feel free to give me an affordable suggestion. Also, do you guys think a high output alternator would be necessary for a late 90s Tahoe if I wired another battery in the trunk?

What's the difference between copper and aluminum voice coils?

So I've been trying to sell my gear for sometime.Facebook,Craigslist,etc.I cant get a hit on my offer for shit regardless of my offer.Everyone around here is hung up on Memphis Audio for the most part!an also pioneer,sony,kenwood,etc!!! What should I do? Maybe I'm asking to much I dont know, enlightened me!!

Like It states im building my first system. So along with that comes alot of questions, and alot i have. Through research I have found most of the info I need but I just need other options or maybe Im going in the wrong direction. So with that said lemme explain. I have a 2002 F250 Diesel That I am looking to upgrade my sound. I am not looking for a major system that will make my neighbors go def its really for my enjoyment. So What I have questions about are set ups in general. Ive currently got a head unit already it is http://www.docs.sony.com/release/specs/CDXGT55UIW_mksp.pdf . I Have a amp sitting around but I dont know much about it. it is a pioneer 2 channel rated …

Make a 1200 x 1 @ 1ohm/4ohm amp? I'm there Welcome aboard. - Steve

I'm currently running a fi audio sp4 15 at. 5 ohms with a hifonics brz. 1700 amp. I have a 350 amp alt and a xs power d3400 under the hood and i'm still having problems with my voltage, when the sub hits hard i drop from 14.5 to 11.7volts at some points, what else do i need? More batteries or is it the alternator? The alt was bought of ebay from BnR parts. Just wondering if i should send the alt back and look for a new alt. And if i did send it back what amp alternator should i be looking for? I plan to get a crescendo 3500 within the next few months.

I did some research and here's what i'm thinking of putting in my grand prix. Headunit - Pioneer DEH-P7700MP 6x9's - Pioneer 5-way TS-A6991R 460w (80rms) or TS-D901P 350w rev series (60rms) 6 1/2's - Pioneer TS-D161R 260w (60rms) Subs - 2x P312D4 1000w (500w rms) was thinking T2's but that's overkill Amp for my high's - P4004 100w x4 (gets more but don't need it) Amp for my subs - P8002 (should net me 500w rms to each sub) Anything you'd change? Reasoning? Box suggestions? Edit: upon further research a P2002 should net me near 60w per speaker instead of using a 4 channel P4004

I've been looking at peoples builds that involve walls. My question is could you just build a box and stand it up to facing forward then seal it off? How come you have to secure the box so much when its walled but when you have it laying normal it doesn't have to be?

Just got a 95 altima little 4 banger already going to replace the battery looking to replace the alternator but question is how will i know what alternator will fit and how big should/can i go? also the big 3 will be applied poor poor electrical system

Just bought a brand new f150 stx with sync looking to put my stereo from my jeep back in the f150 the alpine type r components are probably going in the truck as well as my ppi 4 channel i think im going to sell my kenwood excelon 997 considering how much of a pain it would be to replace the stock and im probably going to sell or trade my dcon 15 and custom ported wedge box for somethkng that will fit under the seats in my extended cab any recommendations would be helpful for loc as well as subs and a box for under the seat that could run off the rear channell of my ppi 800 by 4

I'm in the market for a new ride. Wanting to spend $20K or less. It must be 4 or 6 cyl. (not 8 because of high gas prices). I prefer Honda, Nissan, Toyota & Hyundai. I have (2) JL W7 12s powered by (2) JL 1000/1s. I currently own a 4-door Accord & have the (2) 12s firing towards the rear. The bass is nice, but my truck rattles BAD. VERY annoying. I've tried firing woofers forward in this car & was not as impressed with their performance as I was with them firing towards the rear. I need your opinions. Should I go with an SUV & fire them towards the rear? If so, what's an appropriate-sized SUV for the 3 cu ft. box required for the 12s? And how much space sh…

im looking to build a custom box for an impala. i havent built one before so i was wondering how do i tune the box and what dimensions should i use for two 15 inch sundown nightshades? also what tools do i need to build the box and what tools are required for clamping your amp?

Ok hey guys, im new to this forum. Im guessing you guys are type experts on subs if not, any information helps. I have a 07 BMW X5 and I just bought a 15" Soundqubed subwoofer and a x14 brutus hifonics 1500 watt amp I want to wire to 1ohms, and im doing it also to my stock head unit. My battery is in my trunk so I don't have to wire a lot to the front of the car. Also wiring with 4 gauge. I was wondering what would the dimensions be for my box? length, depth width? volume? what could my sub displacement be? and my port displacement? Im thinking also 4.5 cubic net tuned 34-38hz please let me know give me ideas, info, anything thank you so much GS

My dad is going to help me build the enclosure with his CNC machine so things should go smoothly when cutting the boards to their correct lengths. Right now I have a 2.3cu. box tuned @ 33hz (which I built it myself) and it gets decently loud, but I want to get louder which is why I decided to make an enclosure which will hold two Icons. I listen to a variety of music such as heavy metal, alternative, rock, R&B, rap, techno, and some dub step. I will get back to you with my trunk dimensions when I get home from work. I want to use this box as a daily use, but I still want it to get loud. What type of box will be the best to build to achieve this? On a side note, I als…

Hey fellow SSA members, tonight i am devoted to learn this to the fullest, so there will be a lot written.. and questions as i go along, big thanks goes out to ANeonRider because this is all based off his How To: Set your Amplifier Gain - SSA Car Audio Forum (I'll be working at the thread for about 30min to an hour before posting) THIS IS GOING TO HAVE QUESTIONS THAT ARE DUMB... but i need to ask them to get it clear and have no doubts. To figure out what voltage you should set the gains to, multiply the RMS power of the amplifiers output by the impedance of the speaker, then find the square root of that number. -- I'm going to be using: PDX 4.100 Alpine Type R comps *4 …

I just bought a dodge stealth and I'm having a box built to take up where the spare tire is and I'm gonna be running a Orion hcca 15.2... My problem is amp choice... I've been looking at the hifonics bxi2006d but I'm not sure it that would be enough power for that sub... I'm tryin to stay under 300 for an amp because I still need to by a HO alt and all my wiring... Any suggestions would be greatly appreciated...
