Not bad at all

I purchased this box because of its small over all size. It allows me to have bass in my car.This box that takes up as little space as possible.
I have an Alpine R 12" sub-woofer which sounds great. Bass is really tit and sounds clean. I was hesitant at first because I have not heard a sub in sealed box in a long time. I am very happy with combo.
If you really need your trunk space and want good bass, Then get this!
-> would buy again. :)

Awesome box

I really didn't have high hopes for this box but once I put everything together the sound was BOOM. I have a 2014 Kis Optima w/ a tight seal for the seats so now w/ the new box in good.

Fantastic value

Great subwoofer box and an excellent value. I installed an alpine 12" in it, it m the hole was a touch large but it works. The box craftsmanship is great, im glad i bought it vs building my own.

Great space saver

This box is a great space saver for me, as I have a shallow trunk and am limited in options. I have an Alpine subwoofer in it and everything was shipped to me very quickly. There was a slight tear in the carpeting on one corner, but really not that big of a deal. Terminals are well put together and it’s not overly heavy, while still having quality construction and durability. Very happy with my purchase!
