Now my amp died, CRAP
DOH!!!
The plague is spreading from Bogus
. My JBL 1200.1 in my vette died yesterday. I'm not sure what happen. I was at a car show, had my strobes on all day and the stereo for a little bit when the stereo shut down on it's own 
I figured I had low voltage, indeed I did because the car would not start. I got a jump (it was jumped correctly) and the stereo came on, no subs though 
Within seconds I smell that electronic burning smell. CHIT 
So far, everything else checks out okay. I will replace the amp with a spare 1200.1 but what PITA it is getting the fiberglass out 
I wonder, was it the low voltage or the jump that took it out?
I week ago, I blew up my final Pyle 12" sub in my S-15 Jimmy 4X4. It was WAY overdue. The cone was glued back together from an earlier car accident and I was putting 600 watts rms into it's 150 watt rating.
The PPI amp went into protection mode when I was JAMMING
.
Got home, the sub measured 0.2 ohms. DOH!!!
Replaced it with one of my Pioneer subs, kick ***, it is only getting 225 watts rms and the sound is louder and the bass goes much lower.
Now I wonder if I can get the other twenty-three 12" woofers I have into the Jimmy

i had a guy that had his radio on too low and had all his amps on... he toasted two amps.... i would think that if the amps can't get the power out of the system them they tend to overheat.....alot of watts but no where to go.... also, i would recommended hooking up a small fan to cool it off.... i have fans and it keeps thing cool.......

What took it out would depend on your setup, what type of power cap are you running between the amp and batt, if you are not running with a cap the jump most definitely caused the blowout ( low stable voltage while cranking followed by higher voltage once cranked ) you alternator will put out significantly much more than 13v when the voltage regulator detects very low batt voltage, thus charging at max (above 14volts). one good thing is this is usually an easy fix, inside your amp there is a power diode ( between the input power and main ground ) that is usually what goes out. easy to change and very cheap. next time you jump i recommend removing the power inline fuse to your amps, if you dont have one then the fuse on the amp will work or just unhook the power wire until you battery has cahrged for about an hour then rehook it up.

the sub amp has never overheated before, the entire top of the amp is exposed to the air.
I'm running a GAP 15 farad capacitor right next to the amps.
It will be awhile before I get to look at it, summer is flying by.
