Hey guys looking to add a (stock head unit)line out converter and a small amp for the door speakers and piggyback off the rear rca's for a powered 10" sub (without any cutting) to put behind the seat. I am trying to do this without cutting the harness is this possible? crutchfield says no.. Any ideas?

 

Attempting to decipher your posted info...



Is it a 2 channel or 4 channel head unit?



Piggyback off the converter RCA's?



Your going to have to cut the speaker wires from the harness to splice the converter inline to the head unit.




- If you head unit only has 2 speaker outs, and, your using a 2 channel line out converter, you could use an RCA Y-adapter Monster Cable 1 Male/2 Female RCA Y-adapter at Crutchfield.com to each line out of the converter. That way you can hook the small amp and the powered sub. Use one RCA female plug from each Y-adapter for the small amp, and, use the other RCA female plugs from each Y-adapter for the powered sub.


- If you head unit has 4 speaker outs(Front Left and right; and, Rear Left and Right) purchase a 4 channel line out converter and you'll be able to hook up the small amp and powered sub.


Also, does the powered sub have RCA input or speaker wire input?


- If it has RCA inputs, you'll just need long enough RCA jumpers from the Converter RCA Y-adapters to the Powered Sub.Crutchfield 2-Channel RCA Patch Cables (6-foot) Available in 4 different lengths at Crutchfield.com


- If your Powered Sub takes speaker wires to feed signal to it, then:
for the 2 channel RCA Y-adapter, you'll have to convert back from RCA's to speaker wire to feed the Powered Sub.Kicker KISL 2-channel speaker wire adapter (bare-wire connector to RCAs) at Crutchfield.com


- for the 4 channel head unit, just use a 2 channel converter for the small amp, and wire the rear speaker wires directly to the Powered sub.


With the short info you've shared, hopefully one of these scenarios fit your application.
