Thats a nice setup Morgan. I was originally going to run my old MTX 12s but they require so much enclosure space so I stepped down to 10s. I am planning on running a second battery as well as doing an ad244 alternator swap. I calculate I will be running 2000 watts RMS.
Poly fill makes a small sub box act like a big sub box. You really need to pack it in there though.
One of the reasons I did infinite baffle in my cars was I needed the space. Mount the woofers to the back of the seat on a board and you can still pack a cooler, tent and camping gear and not have to worry about removing the sub box to do it. I dont need that much room now, but I would like to have a small space back there, just for a couple bags of groceries. I like to carry a small tool box and a set of jumper cables, flashlight etc. Thinking about making a compartment space for storing such items. Ive also entertained the idea of fabricating small enclosures on either side, building an amp rack over the 2 and be able to have a space to lay a spare in between for long trips.That looks nice, I'm guessing having room to throw stuff in the back isn't an issue?
