Anyone done an audio install in one of these and has some input?

Hi

Ok, so I currently have an amp and an underseat style sub in an mdf box ratchet strapped to the rear seat hinge- and I want something better as this is currently both to small for bass and too alrge for me to ahve a good storage space.

Does anyone ahve any ideas for a cleaner amp mount/sub bnox suggestions that don't impinge too heavily on the storage space?

I am considering pulling out the plastic tool liner around the spare wheel and trying to shove an amp down there, has anyone tried anything similar before? Woudl there be enough breathing room down there?

Any pics?

Also my amp *just* doesn't fit under the front seat, other wise I would of done that.
