I have a pair of rli-10's on the way to me. (Thanks Mike) They will be going into two separate boxes with these dimensions. Mounting Depth - 6" width - 20" height - 14" bottom depth - 8" top depth - 5" .66 cubic ft. interior air space per box They are going into a regular cap truck, one behind driver seat, and one behind passenger seat. My HU is a Pioneer deh-780. I also have a US amp xt2000d on the way. I listen to rock, country, and rap. I'm still learning about this car audio stuff. Should I put any poly-fill in the boxes before installing the drivers. Do they need anything special as far as break-in? What should I do with the amp as far as set-up? (gain, frequency, etc.) What size power wire for the amp? Do I need a capacitor? Sorry for so many questions, but thanks for the help. Ben
