Review: CLEAN and NASTY - Has good weight to it. Good clean bass, Fits in the OEM subwoofer spot. Excellent quality and function. Easy to install. High durability with more RMS and PEAK POWER than is needed, but still able to put out clean sound from amp. Replaced the OEM sub in a Ford Bronco while keeping the stock B&O amp. The bass is now amazing and NASTY. Couldn't be more pleased. I did have to add some foam around the plastic panel to stop the plastic from rattling because of the extra power from the speaker. Good value for price too.

Great bass response! Good price!

### ⭐ Nonfunctional.
*by P***Y on March 9, 2026*

I was so excited to gift this for my brother. He installed it. It’s only been 2 weeks now and it has “died out”. Nonfunctional. There’s no sound coming out. Maybe they should put “2 week demo” on description.
