Hey all, wondering if anyone can help me out here. I just got a new Kenwood amp and installed it using a PAC SOEM-4 line out converter. Now my front passenger side Alpine speaker is making crackling noises when any power is running to the amp (motor on or off, radio on or off). Sometimes the speaker sounds perfect, sometimes it crackles, it seems to be doing its own thing. I've tried switching speakers and amp channels so I know those aren't the problem. The LOC is not near magnets and my RCAs are as far as I can get them from the power wire.

Has anyone else had this problem or have any solutions to it? It's really getting annoying.

 

the rcas arent ran on the same side as the speaker wire or power cord?

 

No, the LOC is in the trunk of the car where it taps into the signal from the head unit. No RCA wires are ran through the car, they run directly from the LOC to the amps, a distance of 1-2ft.

 

Is the connection on the speaker loose.. Thats a prime candidate for that it happened to me once.. drove me nuts for a week till I could pull the door panel off.

 

No, it's not a problem with the speaker. I even switched it out with a completely different speaker and the connections were strong.

 

Running speaker wires, rcsa and power wires dont seem to casue issues now unless there cheaply made.

So My suggestions is to do the following. Unhook all speakers from the amp. Take a speaker and hook it up to the car one at a time. Start with the bad one. One at a time test all speakers seperatly. Then start adding them together like test the two front and two rear(if there wired to the amp). So lets say you get the noise on one speaker Front LEFT, take that FL speaker and move it to a differnet channel on the amp and see if the noise follows the speaker. Then take a good working ch FR and test it at the same locations of the bad one. Should rule out speaker wire and RCAs the next thing woiuld be the amp casuing the noise. Might be a bad amp.
