hey whats up mc forum. i have a 2004 monte ss with the factory amp for the stereo system. i ordered a new pioneer radio and pioneer speakers for front and back...i got EVERYTHING i need except for the wiring harness. i called crutchfield and the guy told me any gm product with a factory amp is a bose system (i did not know this) but anyway he told me that i need a special wiring harness so i could still use the factory amp and have my door chimes still work. the harness i need is made by Metra and its model GMOS-04 and it costs $99.99. (heres a link to it Metra GMOS-04 GM Factory Integration Adapter Retains OnStar® system, factory door chime, and Bose® system with aftermarket radio in select GM vehicles at Crutchfield.com)

Has anyone had any experience with this adapter/harness? I read the reviews and it sounded like this harness can be a pain in the a$$ but from what the guy from crutchfield told me i need it in order to use my factory amp with the aftermarket radio. I'm gonna get everything professionally installed but i wanna know if this is necessary before i spend the $100. any and all responses are greatly appreciated. thanks

 

I used the same kit but switched it out for a Scosche kit.

It will work just fine, although I think I got mine for much less off Amazon or something.

And if I remember right, the reason I switched was the Scosche kit was louder.

 

i have the best current unit for this gen monte if your interested 30$ let me know i forget the brand its fairly new got it 4 months ago i do ghigh end systems i switched to this one shortly before i traded it in.

 

thank you for your responses...i seen the scosche version on sonicelectronix.com for $59.99...it got pretty good reviews i guess it all depends on who installs it. looks like thats the one im going with thanks again guys

 

can someone send me link for the scosche version and is it basically the same as the metra? crutchfield told me the same thing

 

the metra is the better one. fyi i have one from my monte if anybody wants it. 35$

 

just sent you a PM

 

Get the cheap walmart one, lose your chimes, save your money.
