New here and looking for help. I installed a JVC kwv120bt head unit in my girlfriends 2011 Jku rubicon with the metra install kit, PAC swi-rc and PAC swi-can2 to maintain steering wheels controls due to the factory head unit crapping out. After the install, I have a consistent white noise or static coming from the speakers when the radio is powered up. Everything I've read says bad ground. I've tested the ground in multiple places and even grounded directly to the battery with no improvements. All wires are soldered for best connection. I'm by no means an expert in electrical or radio install but have never had a problem like this. Any assistance in resolving the noise is appreciated. Is it possible the amp with the factory infinity system is causing the problem? Has anyone else experienced this?
