Gen 3 Prius (2010+) Right Subwoofer Enclosure
Grey carpeted, and recessed mounting area. Compatible with HERTZ HX 250D or JL 10W3
The one pictured (carpeted with a recessed mount) is $250, plus actual shipping-$30 less without the recessed mount. Only $100-200 cheaper than a local shop would charge, but you are without your car for a day, or two, less since they don't have to make the back shell with your car in their shop. They will appreciate that.
The back shell only is $110, plus actual shipping. This leaves your local shop only to add the face. Again, they won't need to mask off your trunk to make it, and they will appreciate that.
