Why are there 5 sets of wires for the high level input?

Question

its a 4 channel amp but theres 10 wires ( 5 sets)

what are they all for?

Answer 1

depending on the actual equipment been used, it usually is one for each speaker, and power/remote

so it will be:

- Front Left +-

- Front Right +-

- Rear Left +-

- Rear Right +-

- Power and Ground

but its much simple to use RCA's and much less mess and cables been run. plus, the sound quality is reduced by alot if high level input is used.
