I have a us acoustics usx2080 that i got from Audio Clinic off of ebay and it is hooked up to my pioneer premiere 720prs speakers and it just doesn't seem much louder than the radio straight to the speaker. My gain is at about 3/4 which seems kinda high to me but thats where the DMM put it. My HU is an Alpine 9885 and i used a 1000hz wave to set my gain to 17.9 volts. Someone told me it may be an install problem but what kind of install problem could cause this? Wouldn't it be either working or not working? Also, how much louder should this amp be than the HU? Thanks for any help or tips!!!

Please correct me if I'm wrong. In an instance where a persons deck only allows you to turn up the sub only soo much but you want it louder, in order to make it louder, rather than turning your amps gain up excessively damaging your subs you'd use a line driver. Correct?

Hey guys... I'm about to do the big 3 in my pontaic g8 and the batter is in the truck.. The alt positive is no problem but I'm trying to work out the engine block ground..... What are my options without putting the wire under the car..... Can I ground the block to the chassis and double up on the chassis grounding points near the battery?

i need help picking out a amp a 2000 watt should lanzar be good for my 2 rlp 12" sound splinter

Hey everyone, Got a question. Are Power Acoustik amps any good? One on dealer cost car audio pretty cheap. Opinions please....

Hey, Recently my MB Quart DSC4125 bit the dust and waiting to see if it can be fixed under warranty. Anyways, I have an 8" orphan from Sound Splinter and was wondering what Amp would be good to run it? Either Mono(for sub) and a 2channel to run a pair of Infinity Kappa 682.9cf's or a 4 channel amp again so i can run the sub along with the speakers. Having a hard time finding an amp for a 6ohm woofer that's sweet spot is at 500W. As for budget, not looking to get crazy expensive, say if possible around $300. Just need to be pointed in the right direction. Thanks.

Hey, i have two autotek mm amps. Both of them have "balanced line inputs." The plug in for this looks similar to a s-video plug. In my manuals it says that the balanced inputs accept line level balanced from 0.4v to 18 volts. Also that the XX-BLD can be used as a line driver. I cannot find the "XX-BLD." And also every line driver that i view only has rca outputs and not the plug that is similar to the s-video plug. I've never used a line driver before but i'd like to. And i have an Alpine 9855 2004 model with 4V pre-outs. Can anyone help? Thanks!

This is my first time messing with the GM Data system as my older tahoe didn't have it. I don't care about keeping satellite radio, onstar, or the bose system. I DO want to retain warning chimes, retained accessory power, and steering wheel controls. I'm installing aftermarket head unit, amps, etc. I am looking at either the PAC RP3-GM11 and PAC SWI-RC(~$120), or Metra BX-GM1 and Metra ASWC-1(~$90). Of course saving money is nice, but I don't want to have any integration issues. Just hoping someone has used one or the other, or both, and knows if there are any known issues. Edit: I suppose I should mention I am working on a 2005 silverado.

Thinking about upgrading my head unit to something that is ipod friendly with good sound quality and high pre-amp volts. Eclipse Cd 5030, Jvc Kdr 900, Clarion Dxz 785 are some of my choices, my brother say i cant go wrong with the eclipse, suggestions and opinions will help very much. Thanks alot!!!!!

I have a Soundstream TRX 2.550 and I need to properly set the gains for my subs. I checked the sticky in this section and it says to use the frequency that the bass boosts uses. My boost is +18 from 35-80hz. So what tone should I use?? I wish I didn't have to use the Bass boost knob but I have no other way to turn the subwoofer level down as I am on a factory stereo. If I turn the bass down on the factory stereo it turns the bass down for all speakers making it sound bad. Thanks

IS 389 from an authorized dealer a good price on this thing? Actually, is it a great price? If it is an awesome price I might have to pick it up, but if its just a pretty good price then I think i'll pass. The reason is, I would have to call my godfather and he's in Italy. He'll get it for me for a bday present probably, but I dont want to bother him over an ok deal.

Does it really matter what RCA cables you use from your headunit to your amp?

Hi guyz, Thought I would share this. BRAX from Germany, HELIX Big brother company has/will release.d a new amp. If I understand correctly, it will be a power amp: No Crossover. A german magazine has tested one; specs as follow: MATRIX X4 @13,8V: 4x292rms @4ohm (drawing 136A) 4x270rms @2ohm (143A) 4x284rms @1ohm (186A) Damping factor: 694 @100hz 592 @30hz Size: 330mm x 75mm x 330mm Which is around 13" x 2.95" x 13" (tiny isn't it?) Price: Well it's a BRAX...

okay, I got my Mach 5 15's and i love them. But until i get the money to get the Sundown amp, I need to figure out which amp I need to use in the mean time. So I have two amps, obviously. I just need to know which amp would be better off for me. I am looking for accurate punchy bass more than I am loudness. So please help me out and let me know which is better. Thanks Guys ~MadroX

I HAVE A CLARION 3200A#R 80X4 AMP ABOUT 40LB . TAKES 2 GROUND AND 2 POWER LEADS . IM LOOKING FOR THE SPEAKER PLUG IN AND ANY INFO ON THIS AMP CALLED CLARION AND THEY SAID AMPS TO OLD FOR THERE RECORDS SO NO HELP THERE . WHERE I FIND OUT HOW TO LOAD PICTURE WILL POST THEM . THANKS FOR ANY HELP

so i see alot of people selling used batteries , capacitors, and batt-caps ect. (batteries are what im interested in) and i always thought that batteries and what not lose charge, voltage go dead or what ever you what to call it over time. so can you just keep them charged and they last forever? as always im lost lol

Hey Im thinking of selling my sony xm-5046's but have no clue as to how much theyre worth now. I was wondering whats a reasonable price. anyones opinion with prior knowledge of these amps would be greatly appreciated.

whats the opinions on the newer MB Quart amps. i know galamonkey uses them and ive seen alot of others with them. Im wondering if they share the same boards as the autotek mean machines. they seem very similar, especially being that they are both crappsonics brands. they are tempting bc you know the name used to be good and you can get them for so cheap on ebay.

The local Circuit City is going out of business, they have all their car audio stuff marked down 40%. They've got a few Kicker ZX750.1 amps, originally $500..... and you math wizards have already figured out that they are now only $300. Rated at 750rms at 2 ohms, are they stable into a lower load? Like 1.6 (5 Dual 4ohm coil subs in series/parallel? 1.33 (3 4ohm subs in parallel)? Do they put out more than their rated power?

looking to put a clean sounding (sq) system in a nissan senta. I do not want to upgrade the alternator. Any on a amplifier suggestions in the $500 range. if it costs a little more that is fine also.

Well, I have to ask for help this time. I have a high pitched whine coming through my speakers, even without the car running, so it's not engine noise, but this one is strange. While troubleshooting, I grounded both the radio chassis, RCA shields (Pioneer FTL), regular ground, redone every ground in the car, ran new RCA's, etc etc. So I gave up last night, and decided to sleep on it. This morning, went back out to combat the problem, just turned the key to ACC, fired it up, and it was gone. Went to start the car, and it came back. So I did a little more troubleshooting, and went back in and figured out that with the key in ACC, there is no noise, but as soon as I tur…

If I had a 15" Icon and a 1000 watt amp would I need to get a new battery under the hood, do the big 3 or get a new alternator in a 2004+ Explorer or a 2001+ Tahoe? What about 1500 watts?

Driving a 03' bmw 325i sedan, have a JVC KD-AVx77 and it doesn't fit. The dash kit I purchased doesn't even fit it. I also think that the panel that goes over the dash kit doesnt even fit the unit either. Anyone know what I can do? Am I going to have to customize it?

Alright guys I know this kind of question has been asked before but I just wanted to make sure what will be right for me. I already tried searching for a long time but haven't really found my answer. So I just bought a SAZ-2000D from Mark for my subs and I already have a JBL 4 channel amp for my mids and highs. So what I am trying to figure out is if I should upgrade my alt or just get a second battery. I already have a yellow top upfront and I have the factory 145 amp alt. My system would be around 2500 watts but judging by how the SAZ-2000D did on Jacob's clamp test I'm guessing my system will be close to 3000 watts. I have about 400 dollars left to spend on electrical…
