I just got me one of those Aguilar DB680 thing-a-ma-bobs yesterday. Right now I am using my GK 1001rb as the power amp becuase thats all I have at the moment. I want to get a power amp but don't know which one I should get. I plan on running some Bergantino cabs 1X12 and 1X15. I want something light that wont break my back with enough power to run both cabs. Can anyone make any suggestions?
