  Pinwoofer Powerwave mini amp

  Posted by Brad Carlson on Jan 23rd 2026

  Fairly easy to install. Good directions and videos to follow. Once installed it took only a few minutes to get my speakers dialed in and sounding great. This amp has made a massive improvement to the sound in my John Wick pro. Gunshots sound incredible! Thanks Pinwoofer!

  Just installed the mini amp on Jaws premium and it sounds incredible, honestly maybe because of the John Williams sound track . The bass sounds amazing with the Jaws theme music. My favorite sound quality of all my pins.

  Bought this for a MetR, and this cleaned up the sound nicely. Also helps if you replace the stock speakers. Highly recommended.

  Pinwoofer in Stern Kiss

  Posted by Rick Turner on Jan 19th 2024

  Super easy instalation and what an amazing improvement, then next level again with upgraded speakers. This is the first thing that should be done to any modern pin to fully appreciate the effort that goes into the soundtrack from the factory, especially a music themed pin. Awesome product and right up there with invisiglass and collar displays as a must have improvement

  Jurassic Park Amp + Cabinet Speaker

  Posted by Chris Zumwalt on Nov 12th 2022

  Just finished installing my new PinWoofer amp and woofer in my Stern Jurassic Park (Premium), and I’m quite pleased with it. Install was very simple, and really didn’t take me long to dial in the settings. Overall the sound is much fuller, bass is deeper, and the clarity of the sound overall is improved. I also like having the ability to adjust the levels on the cabinet speaker apart from the backbox speakers.
