Ok,i just put an Alpine 7893 in my 97 camaro.I have the monsoon system in it.Now with the alpine in it,the speakers want to pop,whenever i turn the volume up or down,or when i hit a preset station button.It only does it when their is bass.If i am listening to a news broadcast it is fine.I hooked each speaker up one by one to see if i could isolate the problem,but they all did the same thing.I have tried numerous grounding locations,but no luck.I put the factory radio back in and the system worked fine.I used a scosche wiring harness,but i don't think that's the problem.Eventhough i was told to use metra 70-1858.Any ideas as to what's going on? If i don't figure it out by monday,then it's going to the shop.Thanks

ontiac uses a floating ground system on their speakers that may be causing the problem. From past experiences I had to re wire the system with new wires and it fixed the problem.

Bypass the amp in the passenger side of the hatchback. I think its a waste to use that piece of crap anyway, especially with a nice alpine head.
