Through the great discussion of this board I bought a SVS Ultra sub and a Crown K1 amp. This is by far the best combination I have heard. Here's a quick setup question. The Crown K1 has two channels, each rated 550 watts @ 4 ohm. I am using only one of the channels to drive the sub. Since the sub's max is 500W, this sounds like the right setup. Because I am not using the other channel on the Crown, is there any advantage to bridge the two channels for 1,500 watts? Thanks for your help guys.
