[QUOTE="ac19189, post: 8704860, member: 679575"] Well kids figured it out. After loads of testing and throwing a bunch of noise filters on everything I could think of it turns out the stupid relay for the light bar was the issue the whole time! I had to put a 1 amp diode on the relay to help with spikes from the relay coil. After throwing the diode on the relay the pop is totally gone. Another note is when we turned the light bar off I noticed at times I wasn't just getting a pop but a volume jump as well. At times the deck would jump in volume from 10 to 15 so we originally though it was the steering wheel controls causing the issue so we disconnected them still had it jumping with just the deck. In the end we disconnected the power lead coming off the relay for the feed to the bar which would power the relay but not the bar so near nothing for a power load and we still had a pop so we dropped a diode onto the relay like some old school decks had back in the days and BAM no more pop no more volume jumps.
