The dimensions of the compartment are: 37.5"L 11.25"W and then the depth is a little funky: from the left going right it's 3.25" Deep for 12" and then the rest of it is 4.5" Deep. My amp(s) (tantrum 600.4) dimensions are 14.25"L 10"W 2.35"H, so it fits no problem. The other amp I was considering is the rsd1200.1 for my sub that I get eventually. And that's a pretty big amp for sure. It's dimensions are 19.25"l 11 3/16"W 2 3/8"H so it would fit, but it would be super tight. Well nothing that a big fucking hammer can't fix

Then there's the issue of cooling/airflow, so I figured that I would remove the metal door that's on the compartment now, cut back the carpet, and then replace the door with acrylic. Then mount 3 120mm fans (2 blowing out on the sides, 1 blowing in in the middle) into the acrylic for air flow and cooling. Is this enough? Too much?
I am planning on running 0 gauge to the back, and then have a distro block for the amps. That way I am ready for any type of amp I want to get

I guess my question is this, is it a good idea to mount the amps there?
I really don't see any downsides to it. That way the only thing that would be in the cargo area is the one sub, which would be easy to move if I needed the space. I would also place some plywood down on the bottom of the compartment that the amps would sit on as well. Then I could run wires under the plywood so it wouldn't look messy

I guess I am kinda afraid of cooling with both the amps and the tight space. I know my tantrum got HOT, but that was also behind my sheep skin (yes they are real) seat covers with hardly any room between the amp and the back of the seat, so having a fan blowing on it would be more than it got for the last 4 years of it's life

The compartment is sealed from the outside as well, so nothing will get wet. My RCA's my not reach, but I will probably install a line driver if I get a big amp, so I will buy one so I can use that to "extend" my RCA's if they don't reach and not have signal loss.
Is there anything that I might be missing that's critical?
I will take some pics when I get home in the morning (I am at work now) so you can see the compartment and get a feel for what I am talking about.
Thanks all!
