Does anyone know how to install an aftermarket H/U with logic 7 system?
Hey everyone, I purchased an Alpine head unit from Crutchfield and after some research and discussion I purchased the Axxess kit, this has everything you need to make an aftermarket h/u work with our logic 7 system.
There's a ton of wires from what it looks like and I was wondering if anyone here has experience doing that and can point me to a diy? Any help would be appreciated, otherwise I'll send it off to a shop. Thanks [IMG][/IMG] https://www.crutchfield.com/p_120BM9...Interface.html |

I purchased this:
https://avinusa.com/most-fiber-optic...7-e88-e89.html Works fine for me. You just plug the fiberoptic into the box, connect the 3 wires to the headunit wires, and then connect the 2 RCA outputs to the back of the headunit. |
