4 channel amp...4 channel rca ?

[dh4645]

if you are running 4 rca channels from a head unit back to a 4 channel amp, do you need a 4 channel rca cable or can you use 2 2 channel rca cables?

Use two 2-channel RCA cables. Don't think I've ever seen a 4-channel RCA cable.

ok thanks...
there are 4-channel rcas though, but i didnt think you would have to have one for 4-channel audio.

one other question...on some rcas there is a sticker with arrows pointing toward one end of the cable. does it matter which end goes to the head unit/LOC and which goes to the amp???

[dh4645]

well, i asked crutchfield too and they got back quick than anybody here, so the answer is Yes.
the arrows should go away from the source..i.e HU/LOC.

directional wires .... now that's funny

if you use 2 pairs of RCA's, make sure you keep them VERY close together or you will induce loop area engine noise.

ok thanks, i'll make sure to do that.
if that occured, what would that sound like?

the dreaded alternator noise, it goes up and down in frequency with the rpm of the motor ...... can sound almost like a dentists drill/cleaner
