Up for sale is a custom mounted 10" subwoofer (mounted to painted wood and includes grill), designed to fit under the rear passenger side seat (replacing the underseat storage cover) of a 2000-2006 Toyota Tundra double cab truck.
This provides a stealth, totally hidden look!
I sold the truck so I don't need this anymore. I installed this in 2012 and removed it this year.
You can see in the pictures how it looks installed with the seat flipped forward.
For best sound quality you will want to trim the plastic under the seat as I have done. You will also want to put some sound absorbing material (like carpet or pillow stuffing) in the cavity behind the woofer.
