have an 03 with XM and BOSE, I would like to add a DVD (audio) input, and also add an amp to run a subwoofer. I am planning on using the PAC audio adapters, anyone know if you can add multiple adapters ?

AAI-GM24 for the DVD input and C2A GM24 for the RCA outputs for the AMP

do they connect at the same place (between the cannon plugs connectign the stereo to speakers) ?

thanks
