car speakers on a home system

[bruce racicot]

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.

I love to cook with wine. Sometimes I even put it in the food.

Indeed!
