Hey Guys I just got an Amp and Sub installed into my car but I've run into a weird problem. My horn noise is extremely low and I'm not sure what could have caused it.

The installer ran the power through the driver side and had it come out right under the "brake fluid" cover in the hood. After that he routed it towards the battery. What could have caused this? Any ideas?

I checked the "Horn fuse" near the battery and that didn't seem to solve anything. Pretty clueless after that. Any help would be great this is an extremely annoying issue for me!

 

Could a mod please move this to the Audio, Video & Electronics section?
