Hey guys, I recently installed a new distributor rotor, distributor cap, and plugs. A few days later I started to get some crackling sound across the speakers. At the same time, I sporadically (sp?) started losing my front left channel and subs. I think the second issue was purely coincidental.

I took my car to the stereo shop where I had everything installed about seven years ago. The took a quick look at everything and determined that my amp was bad. They ran some tests on the amp itself and the 5th channel (Phoenix Gold SA1.5X 4x90 1x120) was dead. As I said, it seemed to be just pure coincidence that the amp went at the same time as the crakling sound started.

Well the issue persisted after installing the new amp. We pulled the head unit and checked the connections to everything, but I still got the crackling. We tried putting in a noise filter and still got the nosie. The noise itself is not always present, and it ONLY happens when the engine is on. If the engine is off, I have no crackling. The speakers are in great condition and everything seems to be wired correct.

I guess my question is, did replacing those ignition related items cause the problem? Have you heard of this before? Could it just be fuse related? Finally, could it have caused my amp to blow? Any suggestions you can give will be appreciated.

Thanks in advance for the responses.
