However like I said before I'd like to give my speakers as much juice as they can handle and have both amps fit in the cargo tray under my amp cover. I use my trunk space all the time and behind the seats isn't an option either. I'm 6'4 235 and most of my friends are bigger too. The size issue is really what is making the search hard. So far all I have found that fits all my requirements are the HD and PDX amps.
