RE: Audio nuts only
My Rockford Fosgate amps have the capability of running two normal
speakers and a subwoofer off two channels, though I bought a separate two
channel/bridgeable amp for my sub. I don't know if most amps can
do this or not, but check them out. BTW, they're NOT the Punch
amps...they're the cheaper ones with the red anodized heatsink. I think
they're sweet for the money. Supposedly the same stuff as the Punches, but
not as insanely bulletproof, and they don't look like a doorstop.
According to the manual, you could run four speakers and a sub off my
4-channel amp (the "4.6" model, i think??).
