[QUOTE="oochulshin, post: 8328053, member: 663619"] Ok, here is the symptom. I hear a pop from both my speakers every time I... touch the brake, turn signal on, and turn steering at low speeds. What I have tried... Unplug everything from amp and no music... still pops. - This suggests that the amplifier (and nothing else) is picking up the noise. Sand grounding spot endlessly, find other grounding spots, and try running ground wire to battery... still pops (running wire to battery made it worse). - Not grounding issue. RMA for replacement amp... still pops. - Not the amp. (I've also tried ground loop isolator on the RCA cable in vain) What I have researched... There's something called an "Accessory Pop" [URL="http://www.caraudiohelp.com/car_audi...eshooting.html"]http://www.caraudiohelp.com/car_audi...eshooting.html[/URL] This is saying that car accessories (brake lights, turn signal lights, electric steering) causes voltage spike that can be picked up by amp. But when I used a multimeter to read voltage going into the amp, I see no voltage spike. Not only that, the remedy (put a capacitor on the switch of all accessories causing pop) is extremely difficult. My options... Voltage stabilizer on the battery Capacitor before the amp Last resort: capacitor on all switches like the link suggested. Any help would be immensely appreciated. (I'm dying) [/QUOTE]
