I have a 2006 Grand Prix GT with the 9 speaker Monsoon sound system. When the car is turned off I am still getting noise or static from the speakers and can't figure out why. I also had bad reception on some stations, but messed around with the antenna on the rear window and it seems to have improved. Is there a known cause for the no power static and a solution for it?

Do you have an Amp and how did you wire it up, also if you have a window mounted antenna, you should have an antenna amp as well, is this still hooked up to the new system?

This is the factory installed system from GM. I believe the system does use an 8 channel amp wired from the factory. I haven't done any upgrades or anything like that. As for the antenna amp I don't know. All I know is it mounts on the rear window just below the headliner and runs a line to the head unit as far as I can tell.

Hi there,

Check all the earths are clean and tight, if you have a static noise with the key off the amp may still be powered up and you may be getting a hum, ask at your local audio store about noise filters, this may also be an option.
