i have a problem with blowing amps.

is it true that if your voltage drops to low for to long will it blow your amp? cause i have 8 12in kicker cvx dual 4ohms. with two power acoustik 4200rms at 1ohm. with 2 yellow tops in the back and one red top for the front. and a 300amp alternator. and this is the second amp i have blown. i do play it on idle sometimes and the amp blows in a day. now when i do play it my voltage goes to 11. something and stays around 12.something while im playing it on idle. do i not have enough batteries or what's? need help to figure out why i keep blowing amps

11-12 volts is not likely to lead to blown amps (although they are Power Acoustik so who knows?)  More likely is you are overloading them.  They may be stable at 1-ohm, meaning they do not go into protection, but this does not mean they are actually designed to sustain a 1-ohm load for very long, especially not at high volume levels.  I suspect you are simply pushing low-end amps too hard and they are burning up.Support the12volt.com

what you mean low end amps to hard and are burning up?  what is in the amp is buring?

If my guess is correct you are most likely burning up an output transistor or two.  Pushing them too hard + low build quality = they get too hot and fail.

oh ok so how to you provent that? and is it fixitble?. also what the amp does is that when i turn off the car the light of the amp stays on too. and even if i take out the remote wire. only way to shut off the amp is taking the power wire out. why does it do that

you can prevent that buy wiring the amps at 2 ohms...if you can. He means even though the Power Acoustik amp says it is stable at 1 ohm the amp MOST lIKELY will not live for long being pushed at that load...because of crappy quality prolly Also how are your gains set???

The way I look at it you have $1200-$1600 in woofers, $500-$600 in batteries, a good $400 in your alt but only a $200 amp?     whats wrong with this picture? You have woofers that will handle up to 6000 Watts RMS Why dont you look into something higher quality that would match the rest of the good equipment you already have Look into a pair of kicker KX2500.1   They will produce real power not just boasted numbers and are very reliable 2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

what about a earthquake phd5000, i kno it says that it is 2 ohm stable but i called earthquake and they said that it is 1 ohm stable as long as you dont run it under 12 volts.  so does that mean that i can run it at 1 ohm all day and run it pretty hard? or is it gonna blow like the power acoustiks amp?

i would say if it dosent say it in the factory specs I would be a little leary.   If you can get a email from earthquake saying they will repair it if it blows up, then I would go for it 2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

You spent the money for the system. If you really want to go cheap get an alphasonik amp, they got a long warranty and i put them through a alot of doodie even outlasted a JL amp. And they are 1 ohm stable. Stop thinking cheap on the amps you invest so much in the other stuff and you bitch out on this one thing.
