I'm about to purchase a JVC KW-AVX820 head unit (double DIN) for my 2004 WRX. Does anyone know if I'll need a wiring harness to connect this to the factory wires?
I know that Crutchfield sells this unit along with a free wiring harness, but other website have the stereo cheaper, and I'm wondering if I should just go ahead and buy a separate wiring harness. I've seen some reviews that claimed the JVC mounting brackets already line up perfectly with the OEM brackets in the Subies, but I'm not sure about the wiring.
Any help would be greatly appreciated!
