Can anybody explain to me what each of these does and how can it benefit the sound I'll be reproducing in my system. The deck I will be using will be the Alpine CDA-9887 Also do i have to or need to measure anything when I do time alignment I wanna be able to do this right the first time and for the last time in my vehicle. Any suggestions welcomed

So one of my friends is selling his CR-X to one of our buddies. But he keeps bein a prick bout it. So he's gonna sell me his Rex. She's nothin special. its a 1990 Si. Which i'm excited about. But the body is rusted to piss. And she'll need quite a lot of work even to just become road worthy. But she runs. Since i'm wanting to upgrade my truck soon. This will probably be where the Q and aq1200 go to. Maybe something a lil more efficient. Not sure yet. Lemme know what you guys think!! any good places for rex parts or any info really would be great! Thanks!

i have an FI sp4 15 in a 2007 nissan altima and recently i tried moving my box around to fire forward like a sealed off trunk. I put it as close to the cab as i could and put pillows and sheets all around the box stuffing it as well as i could, and it wasnt as loud (sounding) as firing it towards the trunk. i then folded my back seats closed and put my box in the cab on the seats so that it was completely sealed off from the trunk ( i have a small box and plan on getting a bigger better one) i tested it out and it was even quieter, like a lot quieter, it had less pressure on the ears, less airflow and everything. Ive talked to people and they say sealing off the trunk s…

Has anyone else noticed google play music streaming , and locally stored music sounding a bit distorted lately?

A few of you know, Nick convinced me into doing my own recones. So I ordered them, they came in and a day later I went to work. One little thing to mention, NO ONE BETTER TAKE AWAY MY ORIGINALITY!!! Props to Fi on the black baskets, shame they won't be seen in my build but they look pretty damn sweet!

Hey everyone, This is my first post here on SSA! I've recently purchased a 2008 Hyundai Elantra SE ( and am looking to build a nice system for it. Keep in mind that I'm a college student and do not have too much money. Basic idea is, the less money I spend the better. However, I do want a system that has nice SQ as well as enough bass that it could make people look my way! You know, maybe at a stoplight or in front of my friends. I listen to a lot of rock, but I also listen to rap. I'm not going to do any competitions, and I don't want to go overboard. I'd have to say my limit is under 500 dollars, and under 400 would be even better. I don't have any components excep…

I need to dampen my entire SUV and am not sure which is the preferred dampening company, each forum seems to have different answers. I am not worried about price as much as quality of the product... What is suggested by this community? Hushmat, Dynomat or Raamat?

So when is the last time one of you saw one of these? Any thoughts, questions, Impressions, rumors, folk-lore?

I went to two local shops recently and asked for help in setting the gains on my system. I asked if that was something they did and what methods they used. The first shop said they turn the HU vol to about 75% and set all the gains by ear. Are you f**king serious! What about my HU and my 4 channel amp? The second shop I went to told me that they had access to an O scope and they would do it at no cost. Wow, I was ecstatic. The only catch is they couldn't do it right then, even though they said it would only be ~15 min. It was 3:00 in the afternoon and the installer said to come back at 7:00 pm, so I was like sure i'll be back. When I arrived at 7:00, the owner of …

So i've been working on box design for my new SA-15's. For external dimensions i have: 32 wide x 20.5 tall x 24 deep for 7.55 cubic feet before port volume or displacement. Wood thickness is .75" Then for a port, i would have the dimensions 30.5" wide , 4" tall and then 18.16" deep. I got the port dimensions from CarStereo.com. According to that site, the box is tuned to 32hz. I was wondering if that was correct or not because i know tons of those sites end up being wrong with tuning. Here's a picture describing my plan. The lines in that picture are parallel... I don't know why the camera says differently. So does that sound alright? If not, can someone please correct m…

On a retail side of things . I am in the works of something huge, that will please every audio enthusiast on this forum . For those of you who don't know I am an internet entrepreneur, and have recently just got hooked in this market. I have something coming in the next month on a retail side of things you guys will love! Still talking to some of the companies you all know around here, but the business model is done. Not much info I know, but just wait !

Hello, so I have a dodge charger Srt with the Boston setup. I took the kicker sub outta the trunk and put in my Fi BL. When I get home from this deployment I'm looking at changing all of my inside speakers. I'm look for sound quality. The bass is there, but I want the inside to be very clean! Help me choose my setup. I'll go with 6.5s in the front door and 6x9s in the back dash. What brand and models and amp do you recommend. I'd like to get it done under $1k but that's flexible. Do you think I should add more tweeters, there is only one set in the factory setup. I'm keeping my factory NAV. And I'm looking at a JL clean sweep or Rockford Fosgate 360.. All options are welc…

I am having major issues with my rear doors opening about 3/4 inch every time my bass hits. It's actually starting to dent the jams and chip the paint. On top of that it is loud and I can't figure out a way to solve this issue since I need the doors to remain functional. Any ideas or input would be greatly appreciated.

I did 2 of the big three on my car, the alt. to battery wire and the battery to body ground, both with 4ga wire. I didn't replace the battery to engine ground because the stock wire looks 4ga already. It seems now like there's either no effect or even worse voltage drop and dimming than before. Any input on what may be wrong. Do I need to shorten the wires more there is a few inches of slack, or maybe replace the stock 4ga wire any I did the right wires right?

Well I need to find some screws and I'm not having any luck. They are allen head machine-type screws for the chassis of an amplifier. I've searched high and low locally....from big box stores to mom-&-pop hardware stores to RC Hobby shops. Everything I've found is either too large or doesn't have the right thread pattern. Anybody have an idea of a good store or website to look on to find somewhat obscure screws ?

hi i have had the pg xenon 600.1 on my previous sub setup which was ran at one ohm but i have recent sold that sub and bought a dc sound lab lvl 4 xl 15 which is dual 1.4 ohms i tried wiring it in series to a 2.8 ohm load and it didnt seem like the amp was putting out hardly any power so i was wondering if i wired everything in parallel to get a .7 ohm load would that be safe for the amp. i plan on checking everything again in the morning to see if i can get it to sound right at 2.8 ohms . but if not do u think the amp will be safe at .7 its just for daily driving no competitions or anything

Hey, what's up everybody? So, I've got this build going: My Build I'm working on the battery rack and would like to get some thoughts on this design I've got. I've changed it up a little bit from what I had in my build. Let me know what you think, what you'd change, maybe what some of you have done or are doing now. Now some pics: Here is deal. Chevy Suburban with the batteries between the frame rails where the spare tire would be. Here we are looking down on the setup. Looking from the bottom up. Here is a close up of the hanger. The tangerine pieces are 1/4" plate. The gray angles are 1-1/2" x 1-1/2" by 1/8" thick angle irons. The hangers are held in place to the fra…

I was wondering if anyone could tell me or help point me in the right direction on calculating power for the system I plan on building this winter I was wondering what the math problems to figuring out your reserve(batteries), usage(amplifiers) and charging(alt.) would be? And was wondering if there are any websites or post I could check out to find this info?

Hey Guys, I'm going to be building up the suburban hopefully in a month and was wondering if anyone could give me some imput on how to tune a clamshell or 4thorder.. I have not got things measured out yet, just wanted to know the process of how to come up with the right tunning..I am leaning more to the 4thorder design, but any help would be helpfull.. Jay

I am using the following tool to figure out how long my aeros need to be to tune the box. http://psp-inc.com/tools.html It will be a ~5 ft^3 box I want to tune it to ~29 hz I am going to use 6" aeros http://www.parts-express.com/pe/showdetl.cfm?Partnumber=268-354 I want to use 4 of them, for the look it will give the box. What I'm wondering is after I put all this in the calculator, it tells me I need 69" of length. Is this per aero or all of them combined? I would hope that it would be inches total and not per aero. Thanks

I got a phone call from my buddy today and he wants me to build an enclosure for his step dad's jeep. The woofer is a 12" Sony Xplode that he used to have in his truck. I have NO experience with this woofer. What would you guys, if you have experience with it, recommend for the airspace for a ported enclosure? I'm not sure on the power, I'm assuming like 300w though.

am looking to buy on-line. kicker l7 15 pair. and rockford t 1000 amp. thanks

Ok i read up on my kicker 750.1 , and people on the web said they are running it at 1 ohm . I also know that kicker says it ca only do 2 ohms. how safe is this? If by chance i can run this amp at 1 ohm ,which would be better . a cadence txa 750.1 d, or the kicker. also i can run the kicker at 4 ohms and it will be 375 rms, on the other hand i can run the cadence at 1 ohm . Now being new to cadence is it even worth messing with. because i have 2 of the same amps and i cn strap them together to get 1200rms at 2ohms . Or should i get some subs that come out at 2 ohms to work with the cadence. or just sell everything and start over. my subs are alpine type r's dual 4s. Help
