Purchased this subwoofer as a replacement. I have it paired with a JL Audio 250/1. This sub hits hard. Definitely worth the price.
Great single sub for a hatchback by Polobuddy
The installer suggested the speaker for her car and it is truly amazing.
Great speaker but allow some time to warm up. by Johnstamos22
great sound and perfect bass. Not an overpowering effect but just enough to fully enjoy your music. Make sure to break it in before you turn up all the way.
Great for car system by BryanB
I am not the most technical when it comes to sound. I got advise from a cousin and others and said these were good. They sound great. I usually like my bass to compliment my music and not mask it and this does the job.

Best bass on the block by Mason1215
Quality over quantity describes this subwoofer because I'm often asked how many speakers are in the back and people are shocked when I say "just one"
