I am planning on installing a JL audio Clean Sweep in my Monte. I have been reading about the factory amp bypass. It is still not clear to me when it is needed or if it is needed at all. I am going to keep the factory radio in my car. I have aftermarket interiors and 1 12 inch sub. I am going to use a 4 channel amp to power the interiors and a 1 channel mono amp to power the sub. With this set up will a bypass be needed? To me it makes sense to bypass the amp because I will have another to replace it. Any help will be appriciated. Thanks!

 

I sell Jl products and can personally tell u the clean sweep is an amazing machine lol. I dont know if you will need to bypass the factory amp but I know in my car I did and really ur absolutely right it serves no purpose wit ur set up

 

i looked into it before, i was told i would need to buy a bypass/conector for about 130 bucks. i too wonted to keep the old amp and just add two 12,s. also somehow without the bypass it would affect the onstar and the message center ?!

 

Wow! $130 is a lot! I found this on ebay and I'm pretty sure it is the bypass harness I need. http://cgi.ebay.com/Metra-70-2048-Factory-Amp-Bypass-CHEVROLET-MONTE-CARLO_W0QQitemZ300311219165QQcmdZViewItemQQptZLH_D efaultDomain_0?hash=item45ebf18bdd&_trksid=p3286.c 0.m14&_trkparms=72%3A1205|66%3A2|65%3A12|39%3A1|24 0%3A1318|301%3A1|293%3A1|294%3A50

 

bestkits.com will tell you everything you need to run aftermarket audio

 

thats what it was, a bypass harness!

 

The factory amp can be bypassed with a $10 bypass jumper.

Or you can find the how to online and do it yourself for free

 

Thanks for all the help! Looks like I'm buying the one I found on ebay.

 

Is this what you are talking about?...http://www.sonicelectronix.com/item_...a+70-2021.html

I have a 2004 and this is for a 00-01. Its says that it "Allows for the installation of an aftermarket radio using the existing factory wiring and connectors" I'm not installing a aftermarket radio, just the JL Clean Sweep. Will this do the job?

 

That is the one I was talking about......I has seen a how-to online but after looking at it again I realize it didn't specify what years Impalas/Monte Carlos that bypass worked on. I stand corrected.

After looking into it more, you have infact found the correct bypass harness!
