Great adapter
This was a well priced adapter that I purchased to add an amplfier to my stock C6 Corvette. Overall, it was very easy to use. The connections to the stock harnesses were a little snug - but I would rather have that than a loose connection potentially affecting the system.

Perfect fit
This product was exactly what I needed for my Chevy with the Bose stereo so I could add an amp and sub. Thanks

Review for PAC ADD-GM24
A necessary item for installing a sub in my '11 Corvette. I had to
modify the speaker out leads to accept RCA plugs which was a simple
DIY project on the covette forum. The harness works well and does the
job.

I purchased this product to modify for use in my 2008 Chevrolet Corvette ZO6 to adapt RCA connections to add amps to the OEM Navigation system. Worked very well. I would suggest this product if this is what you are attempting to accomplish.

PAC ADD-GM24
I bought this adapter to use on my 2008 Corvette. I gave it to my installer of a subwoofer hoping it would make his job easier. It really did and he was glad to have it. Great product and a must for all Bose and non-Bose Corvette stereo modifications.
