my car is an 06 GT with Bose system.


I installed an Alpine HU and Metra dash kit + wiring kit WITHOUT the PAC ROEM-NIS2 and the system sound SUPER GREAT!!!

I installed it as i normally do on a non-bose vehicle. Wired up the Metra harness to the alpine harness.

Although the volume is really loud at low level, like from 3-8 its really loud!! Im sure if you keep it under 10, your Bose system will be good.

So the PAC ROEM-NIS2 is not really a MUST HAVE for any aftermarket HU + Bose system..

so far i haven't hear any buzz/noise/pop that mentioned here..
