I have an AVR with Pre outs & an Adcom 7605 5 channel amp. Is it possible to run 2 channels of the Adcom to each front speaker using the Pre outs on the AVR?
I'm trying to double the wattage going to my fronts and still have another channel for the center speaker, letting the AVR amps take care of the surround speakers.
Is this a good idea?
If your speakers are biampable it is possible but pointless. If tgey aren't you could just plug ghe two channels directly into each other and wait for the smoke,
Double power is 3dB or about one notch louder. Not likely a big deal. With typucal crosdovers in the 2 KHz range the tweeter only gets ten or twenty percent of total power so you cannot really achieve double power anyway. More lika a 1 dB (barely noticeable) gain.
