The JL Audio XD amplifiers are really amazing. This amp in particular is very flexible with six channels, 3 cross-overs, and adjustability for 2, 4 or 6 inputs. I am using it to run the front and rear speakers in a Mustang along with the subs in the doors. This amp is very compact especially for the power it puts out. I have it running six speakers thare are all about 2.5 ohms, which puts it at about 90W per channel. After running the amp hard for 30 minutes, it wasn't even warm to the touch. I would highly recommend a JL audio class D amp.
