Ok so I'm finally putting a sub in my car and I was wondering if you guys had any good ideas for me as size and placement from y'all's experience's. I was thinking of a single 12' sub with a custom box under sway bar but I've been hearing its better to put the subs behind the driver and passenger seats, is this true ? And if that's the case will 2 10' cvx be fine behind The seats? Im trying to be heard but with a clean sound and no junky rattling
Thanks guys.
