I just put in the factory subwoofer sold as a dealer aftermarket accessory purchased for my new 2008 Subaru Outback 2.5i Partial Zero Emissions vehicle (PZEV) a few months ago
Part Number: H630SAG000
The audio perfomance is outstanding, especially in the lower range. I can rattle the seat frames of the car without musical audio distortion.
It installed nicely under the front passenger seat.
Where is that "Phantom of the Opera" CD anyway? I want to play that.
