I just installed a box w/2 10" subs under my backseat of my truck. Sadly the kicker CVR 10" subs wouldnt fit in so I had to put some old school hifonics in. Bad thing is it doesnt really sound too good. The box fits all the way under my backseat and is about 6" high. What subs would fit in there and sound good with the little air space? Also can these subs I currently have in there run at 8ohms. Can I run them at 2ohms even though I have only one voice coil? If not how can I run it at 4? And is there really a differece in 8g and 16g wire?
