Does anyone still make the free-air subwoofer wood plate that fits over the top of the trunk area? I don't want a full sub box that takes up the whole trunk space, just the top plate for free air subs as i still use my trunk for storage sometimes. If it's not made anymore (i can't find one) i guess i can always just make one myself. 1991 Firebird convertible

 

For a vert it be a very tight fit, at best. You would'nt be able to open it fully, as it would contact the trunk hinge panel part. I had a homemade one in my 84 and tried to put it in my vert and barely managed to finagle it into the trunk, but i could only open it about 8-10". Maybe just a flat board w/out the hinge or lower in the trunk there are the two little shelf like areas. I thought about making a smaller board to lay on that, but with two 12" free air CV subwoofers it be to small, maybe even with just one too.
