Hi all,
I have installed an aftermarket headunit (Atoto F7) in my 1999 LE with Bose factory amp using Scosche harness # NN07B. This harness is supposedly specifically for factory amplified Nissan systems. The wiring was fairly straightforward and the unit gets power, but no audio is delivered to the speakers.
I suspect this is an amp issue (not powering on?) but I’m completely lost on how to go about fixing it.
Also, there are two separate wires for ground on the Scosche harness. There is a chassis ground (black) and amp ground (black + white). I have tried connecting each of these independently to the ground wire (black) from the headunit and still, power but no sound.
I must be missing something. I’m admittedly a complete noob when it comes to car audio so any advice would help. Thank you
