great sub when installation options are limited
Dean K✓ Verified Purchase•August 18, 2018
Great product, great price. Highly recommend.
Dont buy unless you replace speaker
Sean Evans✓ Verified Purchase•March 25, 2018
The tube and amp are good the speaker ripped within a week, so bought a boss 8" and installed in the tube and it works good.
Not going to handle bass like one would think
Dennis Bak✓ Verified Purchase•March 5, 2018
Not going to handle bass like one would think. I would call this unit a mid bass. That is the kind of quality it will perform without distortion.
Great Sounding At A Great Price

It was pretty simple to install and it sounds great! The price is great compared to other companies and I'll definitely purchase from this company again in the future!
Sounds good

Just what my truck needed, fits under back seat of my Chevy King cab seat. Enough bottom end added to make my music sound complete. Did have a 10" low profile sub, this 8" tube sound a lot cleaner and has a better bass sound.
