I have an little aftermarket system. Not much at all. I did away with the AMP. Put a Sony Xploid(sp?) head unit. And 4 speakers. I've had it for about a year now. Here is the deal....
About a month ago I srated hearing ticking in the FM stations. It is light but there no doubt. It speeds up with RPM. On CD its dead quiet. I removed the head unit and re spliced al the wires for extra measure. Cleaned ground... No help. So i changed the location of the ground from factory ground do frame ground. Did nothing...
Any ideas on what to check next? Maby a head unit problem? I didnt add any new mods right before hand. Only thing that i can think of that i could check is maby a shorted wire from my shift light (ignition wire)??? Would ignition cause it? (rmp sensitive)
Thanks for your help if its possible to troubleshoot over the net. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Seriously, I think it is some kind of frequency interferance. This may sound strange, but for about 4 to 5 months a year, my AM reception goes in the toilet with my aftermarket head unit, but not with the stock. I have also heard of aftermarket plug wires causing problems.
