A lot of these amps have dual imputs that allow for pass-through to
another amplifier. Of course, I'm not talking about a Kenwood
all-in-one home stereo. You can usually find old Crowns for $50-100.

2 Ohms is usually considered the low end. However, the problem with
driving too many speakers from a single amplifier channel (or bridged
two-channel amplifier) is that you reduce the damping effect of the
amplifier by having bleed current between the two speakers. If I need
to drive two subs, I feed the signal to two channels in the amp and
don't bridge it. If I'm driving a single cabinet, I'll use bridge mode
to get additional power and damping capability.
