I am experiencing interference (engine whine) with a new pinoeer head unit.

I previously had my stock jeep head unit hooked up to a pair of 2 channel amps with no problems, it is only after I installed the new head unit that im hacing trouble. The only thing that i changed was to add RCA splitters to the RCA cables, and change the power/ground to the new head unit.

If anyone can suggest solutions, it would really help.

how is your ground done

If your headunit has a good ground, try grounding the outer portion of the rca's behind the deck. If the noise goes away, the headunit is at fault (not uncommon for Pioneer units) and if it's under warranty it'd be best to get it fixed. If that does not solve the problem, try running a jumper from the deck's ground to the amp ground and see if that does it.
