I have all this equipment sitting in my house from my old competition setup. I am honestly satisfied with the factory "premium" system (except that it just needs a bit more bass) but I figured all this stuff i have at home is getting old so I gotta either use it or sell it.

My question is, is there a way to bypass the factory amps but still get the signal from the OEM nav radio to the aftermarket amps for all 4 speakers and sub. I have some Xtant X series top of the line amps, focal utopias and mb quart q's. Now im sure you can understand my frustration about all that $$$ just sitting there. For a sub, ill have to take some measurements and explore my options but if anyone has some suggestions that worked for them, ill be glad to listen. First thing is first,
i want to know if i can go direct from factory OEM nav radio to the aftermarket amps for both interior speakers and subs.

I have a 2000 GS
