PinWoofer^TM – DIY – “Do It Yourself”

This product is intended for those who want to customize their pinball audio system, have the confidence and technical know-how to do so, but want to avoid the hassle and disappointment of trying to kludge everything together separately, spending the time to do so and likely ending up with a poor result.

Do the math and factor in your time and risk of a poor outcome and you’ll see that this is a very sensible alternative to pure “DIY”!

If you are confused or unsure if this is the right pinball audio system for you, it is not. If this is the case, please select a full PinWooferTM Super Kit using the “Search” option in the upper right-hand corner of the web page. A distinct advantage of the full PinWooferTM Super Kit is that technical support is offered during the warranty period for the original target machine. The PinWooferTM Super Kit is supported by highly detailed installation videos, electronic instructions in addition to a well-developed blog that has tips and tricks to get your machine sounding great.

The PinWoofer^TM DIY system is minimally supported outside of the warranty terms, and while instructions for connection are provided, technical support is not readily included. The DIY is brutally simple and if you have a problem, please take the time required to diagnose what might be wrong with your setup before contacting us.

The heart of the PinWooferTM DIY system are the custom amplifier and power board. The amplifier and power board (the most challenging items to get right) form the basis for this product and are always included. It is also largely plug and play using the factory speaker wire harnesses and audio source. A custom power cable is also provided.

For Spike and Spike-2 titles, a mounting bracket is supplied that is secured to the backplane using high-bond double sticky tape. Optionally select backbox speakers and included mounting ring set. Optionally select a cabinet speaker and mounting ring.

Select your title, trim and store options as you progress, and we’ll provide the correct gear.

PinWoofer^TM – Optional 8in Cabinet Mounting Ring

Vital for good cabinet sound - this ring has a 0.375" dwell that allows for cone and surround excursion when the bass is pumping.

The PinWoofer cabinet mounting ring fits a standard 8" speaker mounting hole pattern of 7.625" +/- 0.125" diameter. It also matches the cabinet floor bolt pattern found in Stern SAM, Spike and Spike-2 machines.

Most 8" woofers have a standard hole pattern that fits this ring, but you must verify your woofer dimensions prior to ordering to ensure your speaker fits.

This is a rigid PVC injection molded ring that is offered nowhere else. The rigid material provides a tight coupling to the cabinet which improves efficency and tonal response.

Ring secures to cabinet floor, and the speaker mounts to the ring. Included are eight each #6 flat washers and #6-32 nylon locking nuts.

2.1 MAX Amplification - 50Wx50Wx100W Final Stage*

Optionally select other items as listed to support your install.

Optional Line Trimmer:

If you use an external subwoofer, streaming device, etc. and source it from the Amplifier’s Output jack, you can simply connect to the 3.5mm TRS Output Jack. However, the Line Trimmer allows for the output level adjustment to be extended to the coin box location for convenience. Option includes i) one Line Trimmer Unit, ii) 3ft, 3.5mm TRS Male to 3.5mm TRS Male Stereo Cable, iii) one 12ft 3.5mm TRS Male to RCA Male Stereo Cable and iv) Adhesive Double Sticky Mounting Pad.

Spike Instructions

* Average maximum amplifier power in application can be approximated by taking the product of the MAX power rating per channel and 1/(√2*1.5) and average maximum RMS Power is determined by a further 1.5 divisor.

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 DIY Amp + Cabinet Speaker

Posted by Chris Zumwalt on Nov 12th 2022

Just finished installing my new PinWoofer DIY 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.

Perfect Solution

Posted by Craig Hughes on Mar 17th 2022

I came across the DIY solution after having great experience with GT Pinwoofer on my JJP. I replaced my factory 4 1/4 in speakers with Kenwood KFC-1366S 5 1/4 in to accompany the Speakerlights.com Deluxe kit mainly for LE looks on my premium Deadpool. The sound at proper 4 Ohms was garbage, not just volume but overall... Looking for another solution with a clean power source, external amp, sub out, and equalizer controls to really take advantage of the Kenwoods, I came back to Pinwoofer. This solution fits the bill in everything I needed. The Kenwoods may not perform as well as the Pyle's which come with the full Pinwoofer GT and KO kits, but they sound great and much improved to the Spike Amp to my ears, so if your looking for an LE look with the White speakers and a perfect sound package, this is it. I am also using an External Klipsch 12 inch sub with the DIY amp and it sounds great add well, nice tight bass thump without scattered muddy sound that I was getting from the sub out on the internal amp I was using earlier. A+ across the board!!! Dan is always very responsive and a great customer supporter as well. Can't say enough good things about Pinwoofer and Dan!
