I have a 1994 Buick Le Sabre. My mom put a system in the car about a year or so ago and then got a new car and gave me this one. The CD Player is a Pioneer Mosfet 50Wx4. I have a stock Bose 6x9s in the back and I think 4x4s and tweeters in the front doors. In the trunk I have 2 10'' Fosgates peak watt is 300 and have a 240 watt pioneer amp pushing them. Could I bridge one speaker per amp if I buy another amp, or would that be too much for the speakers?
