Hi all, I have a 2011 Screw and I want to redo my audio while retaining the stock (non-nav, non-Sony) HU. The thought here is to maintain Sync functionality and the stock look, making all the changes on the output end. I'd also like to maintain balance and fade functionality, for OCD purposes.

I want to run Polk MM components in the front, Polk coax in the rear, and two Polk 12" subs in a Supercrew Audio box under the rear seats (yes, I am a Polk nerd). I'll be running the fronts and rears from a 4-channel amp, most likely the Rockford Fosgate PBR300X4 (http://www.crutchfield.com/p_575PBR3...2#overview-tab) due to its small size. The subs I would like to run in parallel from a single mono amp, brand I haven't settled on yet. Something on the order of 900w RMS at 2ohm.

I know that I will need a PAC module to convert my stock HU speaker level outs to four line level outs (F/R L/R). My question is, what's the best way to incorporate the sub amp into the equation? Is there another PAC module that adds on another set of full-range preamp outs? Or will I need to switch to a different speaker amp that has a set of passthrough preamp outs? (don't really want to do this as the Fosgate seems to be a nice part that is really ridiculously small) Anyone have any experience with passing the preamp signal through one amp to another?

Thanks in advance.

You can use a couple of RCA Y adapters to split one of your sets of channels (front or rear) to give you a feed into your sub amp.

^ this. Run your 2 sets of RCA cables to your amp location. Then add a Y to one set for input to both amps. Or buy a 5-channel amp and not worry about it.

By the way, that is what I did for door speakers. Polk MM6501 front and db571 rear and love it.
