switching out stereo

[Burg Boxster]

No, you will have to get an adapter or rewire at the h/u but Boxsters pre '03 all use copper wiring from h/u to amp. Since then, they all use fiberoptic to connect all the authorized components which unless you found a MOST (fiberoptic) compatible h/u would require complete rewiring.

Good luck

after more research looks like an adaptor and a h/u with multiple pre outputs will work. This will also leave the extra speaker wires to add rear, with only running a couple of wires.
