finished trunks

who here has finished their trunks off. i want to move my battery to the trunk, and add a second one for the stereo. i want them hidden behind the rear seat along with the amps. id also like to mount a sub in the drivers fender well, and put a panel up to cover up the jack. im unsure of how to finish everything and mount it . id prefer not to screw into the sheetmetal. has anyone done something like this or have any ideas??


thanks for the help jason
