does it only turn off after you start pumping it or did it not turn on again after that last time it turned off.

Have you tried adjusting your gain on the amp to a lower level and then turning your head unit volume up to where it shuts off at? If not, I would try that to determine if your amp is overheating. Also, what gauge power and ground wire did you run for your amp?

check the speaker wires going to the subs. if they are making contact, the amps protection wont get tripped until a certain volume. you mentioned that you had it bridged. how did you have two speakers on a two channel amp bridged?

i took both two pluses from each speaker put them together, same thing with minuses and the two pluses went in to the plus terminal of channel one and the minus in chanel two, bu it doesnt matter because even when i hook one 12 up to one channel same thing occurs

do you have each one of the subs connected to their own channel on the amp? from those ratings, i think thats the only way to run the system cool and stable. it sounds like there are speaker wires touching though. like i said, the protection will not trip until the current (volume) reached a certain level. if it was anything else, the protection would trip as soon as the amp turns on.

by speaker wire you mean wire fom the amp to subs? because this is 02 olds aurora and in order for me to keep my wheel integrated controles i hade stick with a factory strereo so i used inline converter, do u think something might be wrong with that?

might be. to which connector is the factory stereo connected to on the amp? is it connected to the RCA connector or the high-level input. the high-level inputs look exactly like the connectors for the subs. does sound come out from the subs before the amp shuts down?

here's the bad news. 1st, if you really want quality sound, i really suggest sacrificing the wheel integrated controls and getting a decent after-market stereo. go with Pioneer if you want hand-held control of the audio. 2nd, Sony does not make good car audio equipment except for the receivers. if you do decide to get the after-market receiver, connect the amp to it via the rca connector on the back.

if thats the case, i'm still leaning towards the speaker wires coming out of the amp making contact somewhere down the line. maybe even inside the sub box. check those wires. if they all seem to be ok, then your problem is with the amp itself.

If that amp[ is bridged to 2 single 4ohms subs, that is your problem, that amp can not handle 2ohms bridged only stereo mode..... And you can buy a steering whell add on piece to keep those functions....

i have the same probelm, i have a 12 inch pionner sub and a 2 channel 300 watt jensen amp, none of my wires are touching, my ground is good, ive tried bridging it and everything, when i turn on my car everything works right until i turn the volume up then then the amp shuts off my sub and the wires spark.
