Man, it's been a while since I've done anything to my truck. I did start my box for the subs and amps. It's almost done. So far it's just as I pictured in my mind. I was going to do a fiberglass enclosure, but I changed the design once I made the sub boxes. This is my first attempt at building a sub box and I think I did pretty damn good. Here's some pics. It's 53" wide, so it is a pretty snug fit in the back of the cab, and heavy, I built it all out of 3/4" MDF.
1 cubic foot sealed sub boxes
1 sub in the enclosure, amp back board in and amp cover routered
test fitting the amps, only 2 of three amps and 1 sub because 1 amp and sub are in my other truck, breaking in the voice coil.
I still have to cut out the top, paint and then put it all together. But I have to take the other sub and amp out of my F150, which is hard to do because it sounds so good.
