Default Noise Issue

A few weeks ago I got into my car and as soon as the radio turned on there was this ungodly buzzing noise coming from the speakers. It was so loud that I thought the speakers were going to blow. Anyway, I just pulled the fuses to the amps because I had to get to work.

That night when I got home and put the fuses back in and tested it, it played fine and the noise was gone. So I just left it alone and its been working fine since yesterday when the same thing happened again. I just pulled the fuse once again and still haven't put it back in.

Also sometimes when I roll my windows up I will get a loud pop out of the speakers.

Do you guys have any idea what could be causing this problem? Any help would be appreciated.

Figured it out. The wire after the speaker terminal, the one that goes to the voice coil, was shorting out on the sheet metal of the door once installed. A few layers of duct tape around the metal solved the problem.

Glad you figured it out. Use electrical tape next time, Super 33+ is preferred.

I would have used electrical tape but at the time I was out of it. Is there any solid reason for using electrical tape over any other kind of tape? I've always grown up using electrical tape for electrical projects but never knew why it was better.

because it is specifically made to insulate electrical connections. duct tape will not insulate in most situations, especially with higher voltages.

electrical tape is rated for specific voltages. higher voltages require special tape. you should see a medium voltage splice kit. takes a skilled electrician several hours to combine two wires.
