What is your source? CD? Analog? If there's enough signal to drive your main amp (using the passive preamp), there should be enough to drive the amp on a powered sub. You may need to check the inout and output specs of the components to ensure proper matching, but I don't see why it wouldn't work.
Can a passive pre-amp feed a powered sub?
I am looking to find out if a passive pre-amp can drive a powered subwoofer like the Carver Sunfire Jr. The output from the sub's crossover will be used to feed an amplifier powering a pair of small satelitte speakers. Will a passive pre-amp work in this situation?
I don't need switching or tone controls or anything else, so it would be a shame to have to get a active lines stage to set this up. Thanks for the help.
