I have a JVC headunit that has a single "subwoofer" RCA output. How do I go about hooking it to an amplifier that has a left & right RCA input?

All of my previous headunits had RCA's with left and right outputs.

I have a Kenwood Mono Amplifier...

 

Did you actually look at the back of the headunit? Most headunits that say they have a single sub out means there is only one pair of RCA's...left and right and not 3 like you would need for a sub amp and 4 channel amp.

 

Sundevil,

My headunit has 2 front speaker RCA jacks, 2 rear speaker jacks, and 1 subwoofer jack. That would be 2 pairs and 1 individual sets of RCA jacks.

I am connecting a mono amplifier with one subwoofer to my headunit. My headunit has "integrated subwoofer controls" and I wanted to take advantage of that if possible by using the "Subwoofer RCA jack".

Is this possible by connecting the RCA jack to either the left or right only?

Could I get a "Y" RCA cable and connect the mono wire as the left and right on my amp?

Thanks.

 

That's strange, never seen one like that.

Yeah a y-adapter will work just fine.

yeah...thats crazy. Ive never seen that before. Whats the model number on the radio?

Like the others said, a y cable will work just fine for what your doing.

 

My JVC KW-AVX810 is like that too. I plan on using a Y splitter to send signal to the sub.

 

A lot of head units have mono sub outputs. Many sub amps also allow you to use just one of the two inputs so a Y is not needed. Check the amp manual or label around the inputs.

 

I have the same headunit. JVC KW-AVX810 I contacted Kenwood's help just to verify that a "Y" adapter would work & they said that it is the simplest way to do it.

I'll let you know when I connect it.. Hopefully it works!

 

You should be fine with just one subwoofer wire since it's all mono. I had an old Dual 7" DVD headunit and I got an RCA "Y" adaptor to ease my mind. I didn't notice any difference in subwoofer volume after I used the "Y" adaptor, but you can check for yourself. That adaptor is cheap everywhere.
