Installed in 2008 Toyota Hilux Double Cab

It's been 2 years since I installed this subwoofer on my truck. Working well ever since. It has some good punch, decent bass, excellent audio delivery.
I'm very pleased with this subwoofer. It's the biggest and loudest I can install to my truck cabin without massive modifications.
It does fit well, you just need to adjust some things behind the rear seat. You get what you paid for, I'm very pleased with the outcome.
