Why are there 10 wires for the speaker level input?

Question

what is each wire for because i dont have the owners manual

... oh and its a nitro bmw 483 4-channel amp

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.
