Update
I'm still getting bad interference. Here are the facts.
Switch 1 is a 300 watt roof light bar grounded to the battery
Switch 2 is my 90 watt(each) hood mounts grounded to the battery
Switch 3 is my 20 inch bar in my bumper grounded to my battery
Switch 4 is my 10watt(each) amber fogs grounded to my battery
Icom 5021. I drilled a hole in my roof, ran the coax cable across my roof to the rear passenger door. Down near the back window. Under the rear and front passenger door sills and across the passenger footwell connect to my Icom which is drilled to my center console. Then my power cable is ran from my Icom to my firewall and through a small hole which leads to my battery. Ground and power connected to the battery.
--------------------------------------------------------
I now am getting a high pitched interference through my speakers when I am between 40-50mph. After 50mph it goes away. Then it returns at a higher, different sounding high pitched squeal between the 60-70 mph range
Taken course of action so far: rewired all my lights using proper gauge wires and male/female connectors. I've moved all grounds from the battery to the factory ground positions. Checked Icom coax and power cables for frays and kinks.
PLEASE HELP!!!! ITS GETTING ******* ANNOYING!!!
