You Britts have fit looking engine bays, that's for sure. Nice Sub setup two. I'm pretty lost as to why you have 6x9's back there, but meh. Are the rearshelf 6x9 slots empty? Is there any way for the sub to vent into the cabin?
Next time you have eighty pounds spare tryi buying a front strut brace

Or maybe even coilovers + pillowtops. Rice might look good but there's no point driving an FTO if you can't enjoy the handling.
