This was my first box. It had one 10" sub, an amp, and a 6 disc CD changer. The problem was it fired straight at the passenger seat. All of my passengers complained the "vibrations" became annoying after a bit. Of course most of my passengers were over 60.
I liked the supercrew box because it let me keep my jump seats. Finding a place for the amps and New CD changer were a problem though.
My roommate solved the problem by building this box for me. I had to remove the jump seats, but my grand kids don't fit back there anymore it didn't matter.
Here's the finished box, with amps, 12 disc CD changer and a storage compartment for the extra CD magazines I carry n road trips.
I think the twin 10"s sound GREAT. And no more complaints about vibrations. Unless I really crank it up. In which case the entire cab vibrates. LOL
