I have a pair of ADS car speakers I was thinking of using as surround speakers in my home system. My question is; can I damage my amplifier running 4 ohm speakers? My receiver has the capability of switching impedances, but it only toggles between 8 ohm and 6 ohm loads. Can I just get some 4 ohm resistors and solder them inline to bring the speaker impedance up to 8 ohms?
thanks, bruce
That would bring up the impedance, but the damping factor would be very poor and the speakers would sound as if they were being driven by a much smaller amplifier.
Wouldn't the resistors also need to sink a ton of power? How much would such a resistor cost? (If you can get it?) Would it need to be heatsinked?

I suspect it can drive 4 ohms just fine, just don't turn it up full-tilt or you'll get current overload.
