      Just order it.

      I was a little hesitant when I did the research on this sub BUT I am extremely happy I pulled the trigger. I had it professionally installed and adjusted it to my liking and men did it wake my nissan z up. It's not a sub in a box but its 400 times better than the stock sub (bose). I also sound proofed my whole trunk before the install.

      Great update and sound

      I updated the sound system in my 2019 Mazda CX-5 NVX QBSTA 900W Subwoofer in my spare tire, Alpine S2 component speakers up front and Alpine S2 coaxial in rear doors. Beautiful sound, and the subwoofer bass is outstanding. A perfect for my application!!!

      This spare tire sub blew me away!!!

      This spare tire sub blew me away. I could not believe the output of the sub for being what it is. I would recommend this sub to someone who requires this application in a heart beat. To say I was impressed is an understatement.

      Best bang for your buck

      Best bang for your buck,plus the bass is loud and clear and didn't sacrifice any trunk space. The wife is happy about that. Great product I would recommend it highly. Thanks

      Awesome product

      I have one of the competitors products in my wife's car so I tried one myself, utterly disappointed. I came across your product and after researching went for it and I am so glad I did. It out performs and doesn't clip or turn off and on intermittently like the other product. The bass **** is an awesome addition. I highly recommend this product.
