hmm few hundred more i can get the whole boot custom made, got that quoted for 700 dollars at autobarn. Thats with the whole boot remounted into a nice design with a fiberglass botom for the amp ;) and still got room for luggage. Only thing is that you lose the spare wheel . But i think i can sacrafice that. ← MMM $700 - $300 = $400? Am I correct cause last time i checked I didn't think that $400 was a few hundred. ;) The back of the box is all Fibreglass and is considerably light. Plus side is you can still access your spare wheel. FYI it wasn't done by some back yard dodgy either my mate runs his own mobile audio business Urban Auto Tek and works part time for JB Hi Fi so I'm thinking he really knows his audio stuff ;)
