2 Amps, only one Audio Out Set

Howdy All,

I am pretty new at this stuff, I haven't installed a car radio for over 15 years! Anyway my father in law has a boat and he needed to replace his stereo in it and I thought I would do it for him. He has two sets of 6x9s, one set up top and one set below deck. From what I can see, each set is power by a sony amp with RCA plugs coming to the head unit.

He just bought a a new head unit (Sony CDX-GT310). The unit only has one set of RCA Audio outs. So how do I hook up the second amp?

Or do I just pull the amps and hook the speakers up direct to the harness?

Please HELP!

Out of training newb!

Welcome to the forum.

Your problem can be solved one of two ways.

If either of the amps your dad has features its own set of RCA preamp outputs then you can simply daisy-chain the signal from the first amp to the second amp.

Barring that being a possibility you can simply get a pair of 1 female to 2 male RCA Y-splitters.

Like this:

and then use the single pair of outputs on Dad's Sony headunit to send signal to both amps at the same time.

This could work if they had male to female adapters.

They would need a 2 female 1 male connection like this. Wouldn't they, seeing the RCA's on headunits have 2 female connectors, which would need to be turned into 4 instead of 1, which is what that 1 female to 2 male connection would do? Correct me if I am wrong.

That would work if you want to run a 2nd pair of rca's from the HU to the amps.

With the 1f-2M cables you can run one set of rca's to the amps, split it there, and plug in. Depending on where the amps are located you COULD need another short rca pair to get to the 2nd amp.
