My amp and head unit cut off completely

[Alex37211]

I have a 95 civic DX (d15)
Okay, this is what happens:
I put an amplifier in my car which drew 60 amps of current and I was pumping about 550 watts into a couple of 12's. At max volume, when a real deep bass note hit, my amp and cd player would power off completely for a few seconds. I think the stock alternator in my car only puts out 90 amps. I figure with the engine running, the spark plugs will draw a good amount plus lights and whatever else is on. And it's NOT the amp or the subwoofer wiring. It's done this with different amps and I know how to set up correct ohm loads. Is my electrical system throwing a switch somewhere from being overdrawn? I want to run about 90 amps of current just for my sound system (including one class A/B 4ch and one class D monoblock MTX and of course my head unit).

Don't I need a better alternator? Or is there another solution?

It won't draw 60 amps continous ......

The amp may be cutting off if the volts drop too low

[Alex37211]

Well how do I keep my voltage more constant?
And are you sure that is the problem?
Is it normal for the head unit to power off along with the amp? Oh and I have the amp's remote wire conected to the 12v switched wire (red) on my CD player's wiring harness. Is this okay? Could it explain them turning off simultainiously?

do the big 3 along with a higher amp altenator and a new battery, shouldnt EVER have any problems then

I know it won't be constant, but won't it spike up to that when the deep bass really hits? And doesn't lower voltage cause it to draw more amps? I put a cap with a volt meter on it once and it would go from 14 down to like 10.5 volts when the bass hit. And that cap wasn't helping at all. I think it was bad. It wouldn't hold a charge at all. Aren't they supposed to hold a charge when they are disconnected?

10 volts is amp frying range...

most caps will not hold a charge for a long time, depends on the cap. That is correct that a lowering of voltage will increase the current draw, if you are going below 12 volts then even your battery is not floating the voltage. You may have a weak alternator/battery.
