i saw on a webpage a wiring schmatic showing one amp wiring into another amp, and then that amp going to the speakers and sub.... is that a good way to wire it as opposed to one amp going to the sub and the other amp going into the speakers...?
which wires were going from one amp into the other, speaker wire or RCA wire??
if it was speaker wire, thats called strapping the amps. only certain amps can do this and you'll get an increase in power, but i think they draw almost double the current.
if it was RCA wire, they they are just using the RCA outputs on one amp to send signal to the next. very common if you don't have a HU with enough Pre Outs.
