Well I was off yesterday and finally got around to making my template and cutting out my rear seat delete. Here are some pics, I still have to mount and clean up the wiring on the amps hopefully I'll have some time next week.
Stereo setup probably weighs about the same as the rear seat that I removed. Battery is mounted in the spare tire well so my RSD fits around it.
other than the wires to be cleaned up it looks like a nice clean install. Only thing I would have done differently was recess the amps under clear plexi.
that's what they make high flow rate cooling fans for . My POS beater Saturn has the system in it to make it drivable, so I know the feeling of liking it loud. In the Mach I'd have to make it louder yet just to hear it over the exhaust( at least until i get the pipes run that is)
