OK, that storage area is (nominally) about 12 x 36, with a depth of about four inches. I'm thinking about making a carpeted MDF "faceplate" to overlay the thin plastic face of that compartment, which the speakers would then mount to, so I could pick up another 3/4 of an inch there. With 5 or 6 inches of depth to work with (or more of I wanted to get crazy with raised rings and fiberglass resin) I could really fit some real speakers back there. Maybe the 6x9's on either side, with the middle split between a shallow 12" sub and the amp that drives it on either side of the latch. A little partitioning to separate the speakers and the sub and we're good to go.
Right?
So what am I not thinking of??
Cheers,
Johnny
