jwdomino Posted April 24, 2007 Report Share Posted April 24, 2007 I have a 2004 GTP and have the d3 recently installed( 2 days ago) MY car had the monsoon system, so i needed to buy the schoche (wrong spelling) "chime/alert" adapter. so now since then I have a low level "hiss" or static on any input or function with the deck off or on. I have checked all grounds, all good, checked the rca level for proper grounding. all wiring wise is good. Does with car running or not. I assume it has to do with the adapter. I am contemplating just swapping the factory amp out unless there is a known issue I have not found. so to summarize what I have checked: ground is good, one connection at bare metal in chassis no uncapped rca's all connections good btw the "mute" wire mod works great! any ideas would be helpful Quote Link to post Share on other sites
cntrylvr79 Posted April 25, 2007 Report Share Posted April 25, 2007 Did you bypass the monsoon amp? If not that's the reason. That "special" harness you bought doesn't do anything in regards to the monsoon amp. That just retains the door chimes, retained accessory for the radio, and off star if you have it.

jwdomino Posted April 25, 2007 Author Report Share Posted April 25, 2007 so the monsoon amp needs to be bypassed? it come with rca's to plug from my deck to the factory wiring. Quote Link to post Share on other sites
cntrylvr79 Posted April 25, 2007 Report Share Posted April 25, 2007 Yes it does. Quote Link to post Share on other sites
