I have basicly the same setup,One amp on passenger side,one one drivers.I just left the ashtrays out of the side panels.I dont know if all k5`s are the same,But there`s more room on the drivers side.My soundstream 10.0 is on the driver side it hasn`t thermal tripped yet.after about a half hour cranked up all the way it smells like I just painted my blazer.So it must get pretty warm.Jon
