Hello everyone! I just installed one of two JVC KD-AVX77s and have an issue. I installed the stereo in a 2000 Mercedes SLK230 keeping the factory Bose amp/speakers. I get loud popping everytime I change sources, pair/use my phone and navigate some of the functions. I used a Metra harness (70-1786) with preinstalled RCA connections as well the factory located Ign, Bat, Grd, Ill & Amp Power-on wires. I did not install the Parking Brake wire as I don't plan to use the DVD functions for video. I'm sure I've left some information out that will help me, so please forgive me. I have to get back to completing the install. Thanks in advance! Kevin
