Thanks for the response, highfigh, that clears things up a bit. In my case, all 4 pairs are rock speakers in my backyard, around pool, etc... Some are really nice (Rockcoustics, Episode), and others are not (Insignia/Best Buy). I went ahead and stuck with the Carver 200W/ch amp, but I swapped the receiver and now using a Pioneer Elite, because it had pre-amp outs. The older receiver I had been using did not have pre-amp outs so I had to use a converter that plugged into the A speakers of the receiver. The sound is so much better going direct with the pre-amp outs. Now I have 2 B&K 12 channel amps that are sitting unused. Guess I can list them on eBay or something. You think there is a market for them?
