Just thought I'd share.
First of all, many thanks to kbkid for his idea(he did this in his explorer a while back), and many thanks to HCCA as he helped me out in explaining everything I need to do. Seriously I asked him shitload of questions lol.
My goal is to hide my amp and make it look neat. I like it simple and clean.
I really wish I could do the same with my sub and box but I love it so it's staying there.
It is not 100% done obviously. I expect to be done with it in a few days. I am waiting on the carpet, which is supposed to get here tomorrow.
This is sort of a mock up but the cutting is not complete as I need to cut out a vent hole. Also I have not installed hinges yet because I want to wait until my carpet arrives tomorrow so I can apply it to them and then get everything screwed up.
I think I am going to add a beauty trim to the hole and black metal mesh behind so it would look good.
Like I said this is just a mock up, I have a 4 channel amp which is not pictured(and it is for sale tho) and I am not 100% sure where to mount the fans yet. I got a few ideas, I just gotta decide which one would work best. More likely I will move the amp up close to the vent so it will get a better ventilation area. Keep in mind, my amp is ZX2500.1 and it gets pretty got as it is non fan-cooled amp even when my voltage mostly floats in mid 14s range.
Finally here's the pics (my bad with the babbling lol)
I only have like 1/4 to 1/2 inch of space between top of amp and bottom of the floor, I think that is sufficent space for airflow to pass through tho. It got a bit crowded as I used 5/8 board.
