[QUOTE="XTRProBoy, post: 2253598, member: 571009"] Okay wait [I]what[/I]??? The guy at Massive Audio told you that? Too much voltage from the HU fried the amp section of the amp? Oh yeah that's rich, lol. Even if you set your "gain" to max (meaning setting the amp for maximum input sensitivity) then you still wouldn't be able to fry the amp from the voltage from the head unit. What could occur with the gain set too high is you introduce clipping which might cause the amp to prematurely fail, but from the voltage on the pre-ins on the amp being too high would not cause the amp to fail just like that. That's utter nonsense. Furthermore I'm sure you had your gain set properly so the clipping wouldn't be a problem either. Overvoltage on the power input could defnitely fry the amp but with most amps if you have a vehicle DC voltage that high, a lot of other things would get fried as well, including circuits in the car, you PCM, your HU, etc. Plus your Check Engine light would come on if your alt was overvoltaging the car (and if there was enough voltage it would fry your PCM as mentioned and the car wouldn't run at all). I'm guessing your car doesn't have a voltmeter in it's instrument panel? It could be that you get have an intermittent regulator problem that is not occuring when you just tested it. A good idea would be to install a voltmeter (in a gauge pod or somewhere else) in the car to monitor the operating voltage. Still, I'm quite sure an overvoltage enough to fry the amp would also set off the Check Engine/MIL/SES light in your car. CCA on your battery and alternator output [I]capability[/I] is not relevant either. No matter how high those things are, that won't to a thing to anything provided the regulator is working right and your voltage is good. It looks like your electrical system is working fine; the amp is more likely to fail from undervoltage/undercurrent from poor electrical connections like a bad ground and power cable that's not large enough. All of which I'm sure are not the case either.
