Okay guys, I have a factory deck in my 2001 Jeep Grand Cherokee and the Memphis 4 channel and 500d for the subs. When I had an aftermarket deck in, everything was fine. Put factory deck using stinger hi level convertor to the Memphis XO-3 3 way signal processor. This piece gives me front/rear+sub output to my amps with only 1 hi level.
The problem is that I have a lot of horrible engine sound thru the speakers, with a loud pop out of my sub when the car is turned off. I used the power/ground/remote off my factory deck wires to power the signal processor. I know it is not with the RCA's or the amps, as it worked fine with an aftermarket deck. Could it be the processor or the hi-level convertor? I have also checked the gains on all my amps with the engine not running and everything sounded fine, but with the car running it sounds like a fast and furious race!! Please let me know something guys. Thanks a ton.

sounds like the line converter is being a piece. check the wires make sure nothing is touching eachother. make sure the box isnt put/mounted near any 12volt power lines as it will get ground noise(engine noise). and also make sure the converter box is grounded. there should be a black ground wire on it, if not then thats definatly the problem.
