From my '03 Boxster S;
CDR23 Radio, OEM Amplifier, BOSE Door Speakers (in their tuned enclosures), Dash speakers, Rear Shelf Speaker.
Worked perfectly when removed this week.
The Rear Shelf speaker has the typical carpet-peeling on the rear, and the plastic is broken in that area as well. I couldn't tell that was the case, until I removed it. In other words, it looks correct as it is, but you could also glue it up. Pricing reflects this imperfection.
I'm thinking $400. ??? Willing to entertain other offers.
