Thanks for all the info. As I look in my manual it states that the amp will do 600 watts into 8 ohms bridged and 900 watts into 4 ohms bridged. Where I'm confused is that I understand when bridging the amp with 4 ohm speaker it sees a 2 ohm load at each terminal, but since its now one channel is that a 4 ohm load. And when they state the power at each load are they referring to a 16 ohm speaker on a bridged amp is now 8 ohms and a 8 ohm speaker is now a 4 ohm load. When I stated I like my music loud I should have said I was looking for more headroom. I have plenty of volume just looking for a little extra punch.
