I have decided to add another 4 channel amp to my system. This will give me 2 4 channel amps, 6 speakers and a sub. That way I can run each set of speakers to their own channel and have the sub across 2 channels. So what i need to know is, do I need some kind of splitter for the pre amps and the blue power on wire so that both amps can get the input needed. Obviously I will run separate power cables to both amps.
Are these cables readily available single ended female to twin male?

I am no guru... but yes the splitters are available. Check out

You can splice the blue remote wire from one amp to the other to allow both amps to be turned on from one signal off the deck.

Depending on the amps you have, you have 2 choices that I'm aware of.
1) most amps have "In" and "Out" RCA's. If you have the "Out" RCA then just daisy chain a Low Level cable (RCA male/male) from the "Out" of the first amp, to the "In" of the second one.
2) In not "In" "out" RCA's then just get a "Splitter" that will have a RCA female on the single end, and 2 RCA males at the other. The males for the "In" on each amp. The female comes from the line out from the head unit.
Be sure to check to see that the filters are set properly (if you have them).
Good luck.

thanks guys, it should not be a problem....
I really wanted the factory (who prewired my boat for an amp) to leave the 4 speakers in the boat hooked up to the deck and the amp would then control the tower speakers on one side and the sub across the other. They did not hook up any speakers so I now have both sets in the boat on one side, the tower speakers on the other and the sub sitting in my garage. Hence the 2nd amp.
thanks again, I'll keep you posted.

Just piggy back it off the existing amp. Split the RCA's. It's low voltage and will prevent having to wire all the way from the head.

Yes Scooby that is what I am doing, bought 4 monster wire splitters yesterday. Now I just have to tap into the blue wire (no problem) then run 2 6ga wires from the battery (about 2ft each). Amp will be here friday, can't wait!!!!

Ok on my deck the RCA comes out with the two male ends, i thought left and right channel and plugs into the amp. The amp runs 4 speakers inside the boat while the deck runs the two in the bow. I want to add my subs and amp from my old boat, how do i wire the rca to the added amp?
