Speaker popping
 

I'm having a bit of a speaker popping problem that goes with the ignition turn on that I can't seem to get rid of and need a little help out. I have 3 amps all grounded and powered from the same location (aux battery bank) and only one of the amps is getting speaker popping issues when the ignition is turned? The only sources running off of this battery bank is the stereo, the ignition and starting is run from the main battery. The amp is brand new and the gains set to the manufactures recomendations. I've tried a stereo pop interupter from pacific audio and tried a jumper from the power wire to eliminate any remote wire turn on issues and am still unsuccessfull. Grounds and power to the amp are 1/0 awg wire as well. Ideas?

I had the same exact issue this spring and was going crazy trying to figure it out. I redid my grounding connections and it solved the issue. I was positive the grounds were good but i guess i was wrong. Hope you fix it soon i know how frustrating that can be

I unhooked everything and re-installed everything over along with resetting gains and now it works good.
