RCA help

[cyberbob121]

Hey guys,

My HU has 3 sets of RCA outs (Front, Rear, Sub) but my 4 channel amp on has 2 outs. I have 2 sets of speakers each running in parallel on channel 1 and 2 so I can bridge channel 3 and 4 on the sub, but how do I hook up the 3rd RCA?

Can I just use RCA front and us RCA rear to the Sub RCA output on the HU?

Thanks

What 4 ch is it, bob?

A lot of 4 ch amps have 4 RCA outs.

It's a wet sound syn 4. It only has front and rear.

That's easy. Plug the RCA's as said matched on amp, front to front, from HU to front on amp and same with rear.

You'll have to look in the manual to see if ch 3&4 are bridgeable.

I figured I just got thrown off by the 3rd output on the HU.

Thanks man, I appreciate it.

That's for the sub amp. If you ever decide to get one one day, you have that option.

If you paid attention and read what he wrote you would understand better and your advice would be better as well.

OP run the RCA's from the front output of the headunit to channels 1 & 2 of the amp

Run the RCA's from the SUB output on the headunit to channels 3 & 4 on the amp.

Setting it up like I posted will allow you to control the sub using the headunit.
