So i have one 4 channel amp and also another 2 channel amp that I want to wire up to two different subs. I have 4 rca outputs coming back from my head unit, but my 4 channel amp needs all 4 of them, can i split 2 of the rca outputs into 4 by using an RCA Y adapter (i.e. one rca output would go into two, and the same with the other one) this way I can use the 2 i split into 4 for the 4 channel and then use the other 2 that i didnt split for the 2 channel amp? Hopefully you guys follow what I'm saying, Let me know thanks!!
so would i wire one Y cable to a positive RCA and then that would be - + Pos. after the split or just + +. Then I split a negative RCA is that - + or just - -?
