Well i just bought a full kenwood sys (cassette deck with remote ,CD changer,capacitor,digital spectrum analyzer,two subs,two 500 watts amps & four 6'5 speakers,hopefully I know how to install the system.

The missing piece of the puzzle is the encloure,the two subs are 12'' & the speakers are 3 way;I'm thinking about customized box,but i'll never give up on the spare tire whatsoever.
