Cheap sony xplod head unit with 4 channel JL audio car amp. Do I need to splice the RCA wires?

I think my head unit has two RCA jacks. It’s one of those XPLOD head units (http://www.xplodsony.com/xplod/headunits/CDX-GT330) with 52W X 4 powering. But my amp has four RCA inputs. Do I need to splice the RCA’s going from the HU to the AMP? Do I need a HU with 4 RCA outs? How’s all this work. Thanks!

Yes you would need either a headunit with 4 rca outputs or 2 y-adapters to split the signal. That also depends on which JL amp it is on whether it has the level setting switch for high level or low level. The you could run a 4ch. rca and cut the leads off at the radio and wire them to the speaker output of the radio and connect the other end directly to the amp, only if your JL amp has that switch for high/low level input.
