Question 2nd mod, overheating amp

o.k. so i decided to throw in an amp and sub while it takes forever to build my fiberglass setup (im slow lol). So i put on a line lvl, 12" in a bandpass and rockford amp, all on stock non sub hu. But today after a 45 min drive to work with the stereo cranked the amp started cutting out. Its never done this before (had the amp 3 year). I placed the amp in the tray above the spare tire, had the table down and the sub on top of it all. So i figure its maybe overheating or at the end of its life. From that long drawn out explanation my question is this.. for those of you who have your amps covered or in the tray over the spare tire, any overheating issues?

No probs with mine. Just to be sure I wired a computer fan to the remote line just to keep air moving under there.

I'm guessing your line-level converter needs to be turned down just a tad. If the level is slightly high, it will cause input clipping on your amp. You can get away with that for a while, but eventually the amp will shut down from this. Sounds exactly like what is happening. Try lowering the output level of the converter and see if the problem persists.

*BTW: I've had my 300-watt mono sub amp buried in the tray above the battery for 9-months now; - covered by the floor panel and optional heavy-duty embriodered cargo carpet. Very little air circulates in there. No problems at all, even during extended high SPL's.

Hope it helps,

thanks, i'll try turning it down and see if that does anything. when i got the convertor it was set about 3/4 on the pots, i backed it down to around half, i'll see if 1/4 does anything to help.

You might not even need to turn it down that much - just a tad. If you're listening and hear no audible distortion when the HU is cranked up, it might just be overloading the amps inputs enough to shut it down. Go slow with the adjustments until it doesn't shut off when played loudly.

Hope it helps,
