Hey guys I am new here.
I just bought a kenwood headunit and a kenwood 4 channel amplifier, to go along with my sub and rockford fosgate amp. so i was thinking id just run 2 sets of rca cables to my 4 channel amp from my deck. Well thats all fine and dandy but now what about my sub output!

I just found out I only have 2 Sets of outputs from the head unit and I am trying to wire to a 4 channel amp as well as my sub amp. Which I am assuming would require 3 sets of RCA outputs. However I only have 2 outputs!


Do they make any adapters? would a line out converter work?

Any help would be greatly appreciated.

 

Ive decided to get some RCA Y splitters. They seem the best solution.

I made this wiring diagram. Please let me know if you see anything wrong, I will be doing the install this weekend. smokin:

 

Might want to invest in a set of line-drivers for that setup.. especially if your deck is only 2v outs. 0_o

 

why not return the new head unit and replace it with a head unit that has 3 sets of rcas
or
invest in a eq

as far as the y adapters ,they will work

 

What are the RCA outputs labeled as on the head unit? Are they distinctly "Front" and "Subwoofer"? That diagram will work, but your only method of attenuating the rears will be using the rear channel gain (hope the amp has one). If not (the outputs may just be F/R) you may want to conside how you'd fade between F/R and sub; you could run both outputs to the 4cg amp, splitting the F output to also feed the sub amp so it would not fade, but you'd regain R/F fading.
