go to JL's website and get exact dimensions before determining that. And there is no rule that you can't put 7.7 somewhere up front that does fit and 6.5's where you are speaking of. Just whatever you do go JL amps and JL speakers. all m class not the mx class and you will be very happy. The 7.7's have better mid bass than the 6.5's.. If 4 speakers a M4/400 amp is plenty
When I was a child, I used to talk as a child, think as a child, reason as a child; when I became a man, I put aside childish things.
