Last saturday at a comp I received some engine noise after vigorous testing. During runs I turn my highs off so I didn't notice the noise until I turned them back on to demo. Well I had added a bunch of metal tape next to a RCA so I figure that was it. After taking all the tape off I still have the noise.
So yesterday I tore into my truck trying to find the cause. I hooked RCAs straight into the HU bypassing the eq, Tried rear preouts, unplugged sub RCA, ran a spare RCA directly from amp to the back of the HU to make sure it wasn't an RCA issue, and finally use a RCA to 1/8" jack to ipod (no engine noise with this). Nothing except for the RCA to ipod got rid of the engine noise which leads me to think its my HU. I plan to do a direct swap this weekend with another amp to make sure its not my amp.
My question to everyone is what should I do? My HU is a kenwood x993 and I checked the fuse on the back and its not blown. I plan to try the RCA ground method hoping that works but if anyone has any ideas please let me know. I would like to get this issue resolved before scrapin this weekend.
I've also checked every ground and they are all the same as when I attached them.
