Fizzed my third Bose amp and was thinking of a after market 4 channel amp that I can fit under the dash. To pull this off I need the smallest size I can get away. Some of you have parked the amp in the trunk or behind the seat and I want to avoid running a harness to far so I am going to try the under the dash thing. There are a LOT of amp's to chose from and I need just enough power to drive the OE speakers. What amp per channel is the OE system and is there any down side to adding a new amp system to the OE. Thanks, Dan
