i have two amps in my 2door jk.both are JL one is 400 the other is 500 mono they are each under the front seats no over heating issue and if the top is ever off they are protected by the seats if there is a lil bit of rain.have a good one

 

Well said! On a different note. I have 2 12" subs with a 300w amp. Originally, it was mounted behind my back seat (it overheated) then I mounted on top of my speaker box but everyone can see it there, it was in jeopardy of getting wet, and it overheated from direct sun with top off. Then I built a cover for the cargo area to keep my stereo from plain eyesight and to protect from random rainstorm, I bought a fan from autozone that plugs into a cigarette lighter outlet, mounted it into the cover and had it blowing right on the amp. Oh, I had to wire a cigarette plug thing in the back of the jeep for that.

End state I changed that last plan as well, I have yet to find a set up I like. I'm always fighting for space. recently I cut my speaker box in half and am currently running 1 12 inch sub, but all scenarios still overheat. Of course I live in georgia so IDK.
Let me know if you figure something out. Oh and I'm 34 and still have big stereo's. Metal just sounds so much better when EVERYONE can hear it!

 

I built a sub box which has a flat back panel. The sub box resides in the rear cargo area. My amps are mounted on the back, bottom portion of the sub box. Since the rear seat back is angled, that leaves plenty of room for the amps to breath. When I need to work on the amps, I just fold my rear seat down, and there they are.

 

I have 2 amps one under each front seat. No problem with heat.

 

So do you guys think mine will overheat under a box behind the seat?

 

What kind of amp is it? Class A/B, or Class-D?

 

I think you should be fine with the amp under the subs. If you are that concerned with the amp over heating make sure there is good air flow. Back when I did stero installs on custom work where we thought that heat might be an issue we would put a couple of small fans in, one pulling fresh air in the other pulling it out on the other side. We just used cheap ones from RadioShack that ran off of 12v DC and used the power from the stero to trun the amp on to turn the fans on too.

It sounds like you're kind of set on three 12 inch subs but I think you might be going a little over board on the bass. My single 10 inch sub pounds pretty hard. Just a suggestion but you might want to think about a single 12 or bouble 12's with a smaller amp. I like the idea of mounting the amp in the rear storage compartment.

 

I would recommend a fan for that location, maybe 2. Here are some pictures of my 400 watt amp under the passenger seat. No overheating. Hope this helps.

 

Yes it is overboard I know lol that's what I'm going for. And I'm set in the three subs bc I bought them and can't return them so I'm stuck with them. And the amp is the kicker zx2500 watt class D amp. Does that help?

 

If you think that is a negative comment, you might want to stop visiting forums, the guy simply stated a fact, most jeep people do not put in that much of a system into their jeeps. He did not say anything negative, actually stated he has been out of big systems for a long time and stated the fact that most jeepers do not put in huge systems and he asked a question. I do not see anything negative about that. Now if he would have said something like, why you putting that in your jeep, a jeep is not made to be blinged or have systems, then I would think he was being negative.

Now as to your question, I am currently working on putting a system in my jeep, I am just going with two small 800 watt amps, one under the passenger seat and one under the drivers seat. One amp will be power the two speakers in the dash and the two speakers in the roll bar. The second amp will power two 10 inch subs in the back.

I am not worried about over heating because in the past I had a TJ and put two 800 watt amps under the rear seat and never had a problem with over heating and summers in VA can get hot and humid.

However if you are worried about heat, I suggest going to radio shack and buying a little fan that runs off DC power and installing under your seats if that is where you choose to install the amps.
