Is USAcoustics Still Around Just wondering as cant find any where that sell them on the net and they haven't updated their site since 2004. http://www.usacoustics.com/

has anybody heard about em.. if so what do yall think bout their amps and subs..

I'll be needing some RCA to run from my HU to my amp. I have some that I got from parts express, but they seem pretty cheaply made.

I am looking at get one of the new ROCKFORD FOSGATE T2500-1 bd Amps And I was wondering if anyone knew much about them yet. I did some reading up on it and it seems like a decent amp for the price. Any info would be greatly appreciated. thanks

I just picked up a Alpine MRD-M1000 mono block for $100 today and need help setting it up. I downloaded the manual offline but its not very help full. Its pushing 2 Earthquake DBX10 in a ported box. Each dbx is in a 1.75cu.ft tuned at 33 hertz. Some of the setting I did today are: input 2ch gain +6db LPF 80 hertz SUB 25 hertz I have been looking online for answers but having a hard time finding anything helpful. Any help would be great, thanks.

Does anyone have any experience with a Digital Audio DHC2154? My only concern is can it do 1000 true rms at 1 ohm. I know its not a great amp but my kicker 1200.1 was stolen and I am trying to work through college and dont have alot of extra right now. A guy on realm of excursion offered it to me for $150 shipped. Is it worth it?

Would anyone on the forum have suggestions regarding fair market value for the following US Amps USA 2000x? I recently purchased a new set of Definitive home audio speakers and am looking to possibly trade rid my old set to a friend for the US Amps USA 2000x pictured below. I've been out of the car audio loop for quite some time and appreciate your feedback. Thanks-Chris

For over a year now I thought my amps were fully shutting down when the dome lights did. They have not been, but I didn't start suffering low volatge the next morning until recently.... which means that my batteries must have been stronger before but doing this over a year has damaged them marginaly. Today I was waiting for my GF with the ACC in the off. After 15 minutes the toggle switchs shut off and the deck shut off...as they should. I looked in back, sure enough the amps were off... wait... the red lights on the 3 KX amps were off and the blue display was off on the SX...but I saw a faint green glow. I stuck my head through the port and looked at the bottoms of the a…

SparkFun Electronics - DSO Nano - Pocket-Sized Digital Oscilloscope seems pretty decent, not sure if it covers the ranges needed to detect clipping from HU and also to set my gains properly...Any input? Thanks.

Just about an hour ago, I was listening to some beats. I stepped out of the car and popped the trunk to observe the sub itself for a second, I was using the remote (if this matters). I then paused it, got back in my car, turned the volume down, and when I looked back at the HU it was black. I pressed reset, turned the car on/off. Nothing seems to work. I don't think a fuse blew because the motor for the cd changer still works. Any ideas? Kenwood KDC X794

About ready to start putting batteries in this compartment in my car and need to line the wall with some sort of padding so the batts are not just wedged in there around wood. I figure I might as well go ahead and get something that can keep this compartment somewhat warm so i can have the edge in better performance during the cold season for when I compete. So, any thoughts? For the side walls, i have about 1\4" gap on each side of the batts for reference sake. Front and rear, I have 1 1\8" gap in front and behind batt bank. I also have room to put something under them as well but if i do , it must be severely thin, like 1\8" thick, no thicker.

ok so my stock harness is fudgeed....how do i know? i hooked up the stock deck.. and i attached a HONDA wiring harness to it and wired up my Eclipse, still no good.. so i decided to wire up the HU directly.. only problem now is i need a direct illumination wire, help plz?

ive been looking at these amps and i saw something about them in another forum i dont remember which one but by the fuse ratings these don't look like that bad of amps at all...ive only saw like 2 to 3 online stores that carry them so they must be fairly new Here is an 8000 Watt amp for $669 http://www.rickiesdiscountelectronics.com/...fier-21714.html and a 3 channel Class A/B & Class D Hybrid Amplifier for $499.99 http://www.rickiesdiscountelectronics.com/...fier-21716.html 2900 watt mono amp for 269.99 http://www.rickiesdiscountelectronics.com/...fier-21715.html These seem to be decent amps if you look at the fuses on them...it looks like they would do the power the…

I'm currently running 2 dual 2ohm sa-12's and plan on upgrading my amp (currently a crunch 1500 lol, it's getting the job done for now) to 2 saz-1500d's. Right now I'm just saving up money for the amps and working on my electrical. I currently added a lead straight from the alternator to the battery. Replaced the lead from the battery to the chassis and sanded it to bare metal. Added a lead from the block to the the battery. And finally today I added a lead from the block to the chassis (using the same spots as the other grounds). Is upgrading this wire even necessary? After I put that on I had a reading of 14.1X. Turned on the system and it stayed pretty consistent not d…

Whats the difference between the Kolossus Fleks Kable 1/0 and the normal KLMX Kable 1/0?? Other than the Kolossus made up of pure copper are the strand counts different? Also Isnt the normal KLM Kable just as good as kolossus? Material wise except flexibility? Thanks. Just wanted some clarification.

i just got 2 new kicker c12's with an RMS of 150 watts and impedance of 8 ohms...wat is the best amp for these subs?

So, I'm currently in the process of setting my gains for my 4 channel amp and mono amp. I've been researching on how to properly set your gains using a digital multimeter, and it seems like every forum and website tells you a different way to do it. The SSA forum stood out to me and made the most sense about gain setting, but it still left me with a few questions. My first question is should i set my gains for the 4 channel amp first or the mono, or does it even matter? When i set my gains for the 4 channel amp i will be using a 0 dB 1000Hz test tone, but what i'm not sure of is what settings should i use for my head unit? A lot of people say to set everything to 0. I'm …

Basically I'm planning on starting a build pretty soon and right now I'm doing my homework on headunits. I've pretty much narrowed it down to these two. They are practically the same price(JVC is $10 more) and the JVC has a few more features like HD radio, 5V pre-outs, etc. But Pioneer seems to have a better reputation, so I'm not really sure. These seem to be the best two that fit my requirements as I need one that is around $150, has at least 4V outputs, and sub pre amp outputs. So which one do you guys think would be the better buy?

My system is currently running active with a 9886, h100 and is powered by an alpine mrp-f250 [email protected] @4 ohm, my speakers are focal access series components(minus the passive crossovers). I have an Eclipse 3242 that I thought was a good amp, but turns out to have some issues. I bought the eclipse for $75 about a year ago and it's been sitting. It looks pretty beefy internally and has alot of fusing (4x20a) making me wonder if it's underated. It's rated [email protected] 4 ohm. And 55x4 @13.8v @4 ohm. I have a friend that can mess with it and hopefully fix it for around $20. I have three options that I would like help with. I can keep using the f250, fix the eclipse and use it,…

Used Birthsheet 2960rms $375 shipped is the price what do u guys think?

Yet another question by me hopefully you guys can help me out Would i be able to run an SAE-1200d for my two 12" Lethal Injections and a RF p5002 for a pair of Re Audio components (it will run at 4 ohms, 125watts each) on a stock alt (110amps) with the big three done?

looking for a new amp that does atleast 1000 watts at 2ohms and would like it to be under 300 any ideas?

Hey guys. Today I noticed a strange noise coming from the back of my Yukon. It sounded like digital fart through the woofers. So I decided to shut it down and go check things out. The first thing I noticed was that my ground wire was basically melting at the ground point. The sleeve for the ring terminal was melted along with about an inch of wire has turned the casing form clear gray to black.I have 4ga currently for the power run, amps, and ground, but plan to upgrade soon as the rest of my parts show up. There could be more wrong, but I am at work and this is the first thing I noticed. What has caused this? Was I just pulling too much current for 4ga or is it a bad gro…

I just got my Batcap 800 today. The instructions say NOT to ground it to the chasis! Does this seem strange to anybody else? I've used caps before and have always grounded them to the chasis. It says to wire it in parallel to the amp. If it's 25% cap & 75% battery why wouldn't you ground it to the chasis? A background on my system...Optima Yellow Top (38Ah) under the hood, Big 3 (1/0), stock alt (80A), going to run 1/0 back to Batcap 800, (1999) US Amps 150X bridged to RE 10D2 in a sealed box .61 ft^3. HU is Panasonic DFX-85. This is all in a 1996 Honda Orthia (Civic wagon). I want to be able to swap my system out without too many upgrades. I have 2 O/S US Amps 20…
