I have a 2004 grand prix gtp with amped monsoon system + onstar. I found a wiring harness so I can hook up my pionerr cd player but it has bad rating from the reviews. I was wondering what I should do, but I have some questions.
How many watts is the monsoon amp?
What wiring harness works good that I can retain my onstar, warning chimes, etc?
I also heard it will cause a popping noise when i turn off or on the car because of a 12v drop, what can I do to fix this?
What can I use for steering wheel control adapter?
I would like harnesses that I can straight plug in for the steering controls and the cd player, but I want it to sound good with no pop or distortion, and retain onstar. More info on my car: 2004 Pontiac Grand Prix - Suggested Retail Value - Official Kelley Blue Book Site
Should I get the GM Factory Integration Adapter(General Motors Class II data bus interface
Retains ONSTAR system, factory door chime, and Bose system with aftermarket radio)? Does anyone have experience of how good it works, by the looks of crutchfield it is a waste of 100 bucks but maybe they are car audio idiots lol
