09 gmc sierra SLE
What size powered bazooka tube will fit in my truck. Most of the stuff i have read indicate that BTA6250D will fit. but if the 8 inch or 10 inch will fit, i would like to use that. i read the 10 inch may require a mod to my seat to get it to fit. so which ones will fit and sound best.
also, in order to use the FAST-9999 do i have to take the radio out???
