Great product! Quick install and haven't had a problem. It matched my amp and works perfect.

This is a must have if you have a bazooka amp. Stop reading and buy it. It regulates the sound so much better and with the turn of a knob you can turn the bass from almost silent to bumping. Definitely worth the money. buy it

Nice to have. Don't have to go in the trunk to screw around with the bass.

i would not recommend this amp for low bass reproduction - while it has good power, especially for the price, the low pass filters kinda suck, you can't get sound reproduction below 60 Hz - i was disappointed because it was sold along with a really great Sony sub, which sounded great on my house/studio amplifier, but really sucked with the Bazooka amp.

My head unit can control the bass from the sub separately but this came with my amp/sub/box/wire kit. I installed it anyway, and it is nice to have. If you need to turn the bass down for a sec its a lot easier to do with this than scrolling through all of the buttons on the deck. Plus if you just want to tweak the bass a little for songs that don't have enough bass it takes seconds. Nice feature. If I didn't have a head unit that could do this manually, this controller would be a necessity!
