Lets say you are starting with a whole new build and you are starting low. So you go with a 5 channel amp. It has plenty of goodies, like speaker level inputs, preamp outputs, that sort of thing. Could you use such an item in place of a LOC for a future system, and hook up a 4 channel amp and a 1 channel amp up to it later.
Something like this for example.
AudioControl D-5.1300
D Series 5-channel car amplifier with digital signal processing — 100 watts RMS x 4 at 4 ohms + 500 watts RMS x 1 at 2 ohms
Something like this for example.
