Replaced stock bose/cd/cassette with Kenwood DDx418

I used the PAC-ROEM NIS2 During install to keep Bose system and make it sound ok.

So there are four harness, one harness only has 1 wire white/blue the other one with 9 or 10 wires

When doing the install i only used the other two as pictured

New HU powers up but no sound, tried radio, cd player with now luck, in the radio manu it said "searching" not sure what that meant

PAC-ROEM NIS2 does not light up (not sure if it does but has the little LED per different speaker.

One wire i did not hook up was the BLUE/WHITE with says "AMP TRIGGER" off the PAC-ROEM NIS2 i wasnt sure where to put it

And i wired the speakers up using the LOW level wires

Any help? Ive been without a radio all week and just want the install finished up

 

here are the guts hanging out

 

Here is the two used harness and two unused, even without the PAC-ROEM NIS2 the same two harness are used

 

Few basic searches had people (in other forums) now powering their stock amp
The bose amp signal wire is green/yellow which is in the main harness so that is out the the way

I wonder if the PAC-ROEM is suppose to light up? Because its not but has power/ground to it

Could be a mute issue right? I dont have the steering functions and the wire is still loomed off harness, the radio itself doesnt indicate any mute and lets me control volume up 35 (max)

again no sound at all, not even a pop or hint of static

 

I dunno how did you hook everything up, But ground terminals from the PAC module should be grounded directly to the car, Not to the head-unit's ground.

 

I ended up figuring it out
It was a installer mess up, making this thread really helped because i was going through and writing notes in the box and then the fix happened!
(swapped power antenna wire for amp trigger blue and blue/white)

i had to pull everything out and just go over it and found it
Now bluetooth and everything is all set, watched some Chappelle on the way to work this morning... wooot
