Civic Si Sedan Sound System?

Question

Can you put an Amp, new speakers, and a Subwoofer in a Civic Si Sedan with Navigation. Its already Wired for a sub and everything, so it would be nice to have the honda Navigation and be able to controll the sub and everything with the touch screen. But can you wire it so the amp just powers the speakers and not the Navigation so the Navi doesnt go out from overload?

Answer 1

Chances are that without installing the factory sub, you won't be able to control it with the navi unit, but you definitely can install an after market amp and sub.
