Stereo ideas

I'm looking for speaker mounting ideas for my stereo. I got 2 6X9's that I have mounted in the rear deck lid and I wanna mount 2 pheonix gold 10's in the trunk. The problem I have is I wanna have full use of my trunk and I'd rather not have a loose removeable box floating around in the trunk.

Any ideas on the best way to permanently mount 2 10's and 2 6X9's while keeping the best use of the trunk space? Asthetic looks certainly don't matter cause after all it's an escort not a Chevy.

thanks for the help

Just get a truck box and put some poly-fill in it. Then experiment and see whch sounds better, facing the back of the trunk from the seats, up against and facing the seats, or at the back of the trunk facing the seats. For me, I don't care about space, so I got a bulky box, but at the back of the trunk facing the seats sounds best for me.
