i want 2 amplifers to power 2 seprete subs i can power it and everything but i dont no wat to do with the rca plugs for the 2nd amp do i need a 2 channel cd player so i have seprete rca's
What you would want to do in this case is go from your headunit out of the subwoofer RCA (if you don't have that use rear) and into one amplifier and then go from that amplifiers output to the other amplifier input.
This way they are daisy chanined so to speak. Hopefully your amplifiers are the same and they have a data link thing that uses a cord similiar to a phone cord. Connect this to both amps as well. Then set the first amplifier to "master" and set the other as "slave".
it depends on the amp, like my RE12.1 has a master/slave option on it so when your running 2 amps you just run a single rca line from the master amp to the slave amp and it works, but im not sure what amps have this option.
if the amp has rca outputs could u conect that to the 2nd amp and still have the first amp at 2000watt rms to 1st sub and the 2nd amp 2000wrms to the 2nd sub because i want to power the sub sepretly
