As you might know, i designed this system to be clean, classy, and have great midbass and overall pretty good SQ....but it also aint no punk. At least for 1 15, choked off by a rear seat, it isn't too bad. It's 2db louder with the rear seat out (ain't gonna happen).... and would probably gain another 2db (or more) if this was a hatch, but it is what it is. I love it. I don't show too much of the Lexus system because it doesn't really smash like my other cars, but i had to post this up
