Pretty much the easiest way is to run speaker wire with alligator clips. Clip to the positive and negative terminals to the speaker in the cabinet and run it out through a mesh grate to your sub.

on the JJP games theres a sub out connection so that really helps. I've always purchased the pinnovators sub out mod (its super cheap), and that seems to work the best

Or you use any line out converter out there, hook it up with alligator clips to the Bass speaker, ground it to the cabinet and run a RCA cable to the Sub.

Or if you want to go bigger, deeper and more extreme: https://pinside.com/pinball/forum/topic/a-different-approach-to-external-bass-amp-subwoofers

I need to start a new thread.

I got one of these $120 with a $10 subwoofer cable kit from them and it works great on my Stern AC/DC Premium (SAM Machine).
I like it because it has volume control on the front of the coin door as well as a separate volume control for the headphones.
I can turn off all the sound from the machine and play with headphones only, which is a big plus at my house...

Just did this for my CV and MB. Boy what a difference. Polk Audio PSW10 $89.99 Amazon.

Has anyone tried one of these powered subs from Monoprice? The description says it does have an adjustable crossover and level control. Plus speaker level inputs, so no Rca cable required.

May I humbly submit another option:

PM if you want a discount.

Thanks

Did you end up getting the Monoprice one? I have 6 or 7 of the Polk Audio ones, you can usually get them with free shipping. I like that you can plug 2 games into one, and can disconnect/move them easily from one game to another, or if you sell the game. I also used one as a replacement for my home stereo when i blew up my other sub lol. Easy to sell by themselves if you want to do away with them altogether too. I've bought cables and accessories from Monoprice but nothing larger -

not the cheapest price ever but not bad $99

Polk Audio PSW10 10" Powered Subwoofer

I got a MonoPrice sub and would not recommend it. There is a thread around here somewhere describing the issues some of us had with it.

How does your compare to the pinnovator product? Does it work on different platforms (stern, williams, CGC, etc)....

I've added Polk PSW10 powered subwoofers to nearly all my Sterns, my Houdini, and my JJP POTC.

All Sterns were connected to backbox driver board via a Pinnovators sub connection module (also recommend their coin door audio control units available for SPIKE or earlier games). POTC sub was connected directly into the game's CPU's audio output using a Y-splitter to allow continued connection of headphone jack on front of game as well. Houdini sub was connected directly to sub speaker connections provided in backbox.

Ours is an amplified replacement for the original cabinet speaker; dual voice coil speaker, mounting ring and amplifier. Fully integrates into the pin with no wires leaving the cabinet.

This differs from the solution you have mentioned (which is a terrific product, by the way).

There are many obvious advantages and disadvantages with internal versus external that will continue to get debated.

You can look through the announcement thread "New Amplified Subwoofer Kits by PinWoofer" as well.

We also offer an amplifier only option for those who have invested in aftermarket passive subwoofer upgrades. It is a way to get more out of the plunge those guys have already taken.

Our kits are designed to be compatible with any amplifier configured to drive a 4 Ohm or greater load (impedance matched isolation transformers). I.e. a pinball sound board and other aftermarket boards.

So far we have been compatible with every pin install. Still, we're keeping track and will document on the web site after customer feedback.

Take a look at the website. https://pinwoofer.com/

Thanks for asking

Very informative and professional explanation. Nicely done.

Can anyone shed some light on hooking up multiple pins to the PSW10? I usually connect two pins to each PSW10 via speaker wire. I have a Stern that has the Pinovators sub kit using the line connection (RCA cables). When I connect the pin, I lose the sound on the speaker wire connections and only have sound on the pin using the RCA jacks. I imagine this is by design however is there a way around it so I don’t have to use a dedicated sub for this machine?
