Amp Overheating
Yea so on these hot summer days that i wont have to worry about in a couple months but for the time being my amp overheats sometimes. It is placed in the trunk in the rectangular cut out. Just driving around and my sub turns off. So I dont know if there's any way to prevent this from overheating. Thank god the amp has a automatic shut off if it gets too hot or else I'd be EFFFFED. Anyways, feel free to share your ideas. ENLIGHTEN ME!

what are the impedances of your speakers? if you're running 2 ohm speakers and the amp is rated for 4 minimum, that would cause overheating. I'm going to assume you've hooked everything up right though and you just need more cooling. PErsonally, I'd make some sort of enclosure around the amp, then have 2 fans, one pushing air out, and one pulling air in on the other side. This way you get a steady flow of air over the amp.

Try moving the amp out of the well in the boot. That gets hot from the exhaust anyways so it's not doing it any favours by installing it in there.
As invasion said, seatback, or one of the side walls of the boot/trunk, is the way to go

I agree with getting off the floor of the trunk. The stock exhaust gets it pretty hot.
I open the pass through in the summer for my carputer. Maybe that will buy you some time while you figure something out. A little cool cockpit air helps.

I didn't read all replies, so pardon in advance.
Mine kicks off on long drives too. I have to be cranking it for nearly an hour before it happens, but it does. You can back the gain down a touch on your amp and/or add a fan setup of some kind. I have noticed having the passthrough in/out and AC on/off makes no difference in my case. If it does, it's 5 extra minutes of play time. Big deal.

Rocksford Fosgate 300w Amp and its bolted down to the floor where the indent is. I cant put it behind the seat or center console because that is where my sub box is.
need a fix. maybe instead of a fan ill just raise it up. I dont know its winter almost now so ill be good to raise some money and fix it before next summer.
Thanks guys

odd that you guys are overheating the amp.
I have a Kicker 1200 watt mono channel that sits in the 'trunk organizer' with the lid on and I've never had my subs cut out.
Those who know me know that I dont go easy on my stereo, I've got an aftermarket exhaust, AND it's over 100+ degrees here in the summer.

If I'm not mistaken your trunk is dynamatted. Do you think that could be the big difference?
With the muffler(stock exhaust) directly underneath it, I know it gets quite warm sometimes.

Holy cow! After AN HOUR it overheats?!
I drove home from Cali to Chicago, over 28 hour drive and my system didnt go below volume 20 the whole time and it NEVER had a problem (Lowered 8 w/ droning midpipe + typhoon intake going 80mph=noisy). I have a JL Amp with 2 10'' W1's and its never shut off from overheating; had the system for almost 2 years now.

Is your power wire building heat? You may need to oversize your power wire to the amp. Is the wire getting overly warm? Heat causes resistance to rise in the wire. As the resistance goes up so does the amperage to overcome the resistance to maintain the voltage.

Check the speaker(s) for proper Ohms for the circuit.
A 2 ohm speaker on an amp made for 4 or 8 ohms will over heat the amp.
