I'm having problems with my amp overheating in my trunk. I live in Arizona and it overheats anytime it's over 100 degrees and I've driven the car for more than 20 minutes.

The amp is hot to the touch so I know its overheating and I only have the problem in the afternoon. Unfortunately its usually over 100 degrees here for like 5 months so it isn't really something I want to wait out.

We just put spacers in to get the amp off the board and maybe increase air flow but does anybody have any other suggestions?

 

You could try building a rack with a plexiglass cover for it and install fans in it facing opposite directions to blow colder air onto the amp and remove the hot air from the rack.

 

^^^^ Not the best of ideas. If he has a issue with heat now, to put the amps under plexiglass is going to compound it in some cases, even with fans. Next issue is that both fans need to be mounted in push mode, not push / pull. This moves no more air than having one fan. If one fan is pushing 500cfm and the other is pulling 500cfm, you are still only moving 500cfm. Put two fans in push mode and you now have a exchange rate of 1000cfm. So all you would need is an exhaust port.

An amp is designed to get hot, no matter what the type. Ensure that your power and most important your ground is of adequate guage or expect the amp to heat up prematurely. Read the grounding sticky as it definitely applies here. Failing this, coming from an area that is much like what you are in, a cooling fan(s) may be 100% necessary. Ensure that the gain is set properly. If you can find a area to draw cool air from or exhaust the hot air to, that is what would be best if faced with a amp rack and plexi.

 

The most obvious and worst location in the trunk is that centre depression.
It gets really hot in normal driving, as it's about 3" from the huge muffler underneath.
Anywhere else in the trunk is a better amp location.

I had a custom box built for the sub and its built into the back part of the trunk. The amp is mounted on the outside of the box. So, its not in the center part.

I'm not sure how I'd put in a fan. Would I have to have them rebuild the box?

 

just waiting for the peltier effect a/cs then u can have a mini-ac for Amps/computers/whatever :D

 

You just need a small fan no fansy ****... or a better amp. i have a JL Audio amp and have no problems. but my old amp which was a mtx overheated and a small fan fixed that problem. Its nice and easy just hooking up 2 wires. I have my amp behind the spare tire in my 8 and have no problems

 

What amp are u using? Some amps have a LED light up when its going into thermal. How do u know its overheating? Does it just turn off? Are you SURE it isnt a loose "remote turn-on"??? I thought mine was thermal, but it just ended up being a lose remote turn on.
