in the integras trunk there is a measly piece of cardboard in the bottom over the spare. but i dont feel real safe putting the sub in the box on top of that. If anyone else has done that or has any ideas help me out.

 

My box with 2 12"s are in my trunk on top of the piece of cardboard. I've never had a problem with that.

 

i've got 3 10's sitton on the flimsy peice. it's fine.

 

that little flimsy board will flex. but its generally no problem since the spare is pretty much going to be supporting it.

you can always get a sheet of plywood and replace that board. or fiberglass it into the side or even where the spare is.

 

i replaced the cardboard with plywood in my hatch. I just traced the cardboard on some plywood and cut it out. it adds maybe 5-10 pounds...but if you're throwin in a system you're not worried about weight.

 

how many of what size subs are you running? that will make a difference... you can always reinforce the cardboard with some firring. i only have 1 8" so it sits nicely in the back of the well....

 

I bolted my Infinity BassLink through the metal trunk floor on the passenger's side. With the cornering loads I generate, I cant afford to have things sliding and bashing about.

What about bolting your sub box to a length of angle aluminum, then bolting the angle aluminum to the body longitudinally, just aft of the rear seat? :dunno:
