I just found this doing a little searching for adding an aftermarket amp and i was wondering if anyone has tried this yet?

It looks very promising although its only for the front and rear speakers from what i can tell although i would think you could buy an RCA y-connector and use the remaining set of rca connectors for your sub.

 

bump and subscribed.

 

The particular model in the link is if you have the existing Infinity amp, but there is another kit by the same company for those who don't have the infinity amp. I still have to do some research on exactly how they work and may end up buying one since I'm ready to install an amp.

 

Thats a really nice piece. This will bypass the factory amp ( on infinity system ) and allow you to keep all the factory controls and give you the line outs for an aftermarket amp. ( volume, eq, fade, balance ) I don't know how the sub plays in to it, but the customer service at pac is pretty sharp and they know their products. They helped me pick the correct L.O.C. for my sub. Let us know what you do and include pictures.
