How to install the 07+ gm navigation without the bose system??

[treyd45]

I have an 08 tahoe with the non bose speakers and wanted to install the Gm navigation radio. But to my understanding you cant do it without the bose speakers... which is kinda dumb. i have 2 jl audio subs and an amp installed into my stock radio right now. What can i do to make the navigation work in my tahoe, if possible

1. You'll need 4 channel amp
2. I made a harness that will let you do this integration without cutting a single factory wire

Ya i ordered the Jp custom wiring kits to do so.. and my gm nav is on the way. but do i have to have a 4 channel amp or can it be any channel amp

Also i already have a sub/amp set up and i have a 2 channel amp that i was going to use would that work?

Where can I get the wiring to add the amp without having the bose system?
