Hey guys Greg from Pinball Pro here. I have done many things for pinball audio including running an amp (several of them), 10” subwoofers, 12” subwoofers, even 15”. Our speakers can absolutely take an amp. There are lots of ways of installing an amp with basic knowledge of speakers and sound.

Why haven’t we offered amps kits?

The first reason, amps are so widely available already, and at a very affordable price. It would not be worth making custom Pinball Pro amps when they basically already exist. It also takes a higher level of installation knowledge.

The second reason, in our experience, the amp is ALOT. The design of our speakers, they already achieve a decent volume level and bass output that is more than sufficient for the above average person. When I say a lot, I mean rattles like a 72 Monte Carlo, it’s just too loud, so we did not see the need. Though we have directed many how to do it. Customers adding an amp do it at their own risk.

How did we do it?

We used a few different kinds, but ultimately found excessive power was money wasted. So no need to go crazy with power. We have used and tested the amps below.

The first is the Dayton Audio Plate amps the SA70 is a lot, the SA25 is very good as well. These drop right into the coin box and plug into the service outlet which works great with the auto on/off feature. It is easily wired and adjusted for correct balance and output.

We have also used several of the Lepai amps, finding 40 watts is kind of the sweet spot, with an adapter you can also use the service outlet or tie it into the power supply.

There are a host of $25 amplifier boards as well, with basic knowledge these can be added to any game. https://www.parts-express.com/tda7492-digital-audio-amplifier-board-2x50w--320-606

If you want really loud and lots of bass, we can do 500 watts and a 12” sub. Let’s be real, the pinball will bounce, LEDs will fall out etc. there is point of no return and it’s time to move external. While it’s cool, most people don’t want so loud you can’t talk.

WE HAVE A SPECIAL CONNECTION ON OUR SUBWOOFER DESIGNED FOR EXTERNAL SUBS. For those wanting Pinball Pro, and the ability to add an external, our subs have a connection for the external sub wiring. We also sell back box only kits for the external guys.

We tested amps 10 years ago through today and do custom installs, and it is easily done. There is no need for us to make or invest in after market kits when there are already easy to use amps. Also many whom have done it agree, it just over kill, but it is still fun to do!

Long story short we have not offered them because it is so easy, and did not feel demand was there. We can certainly look at the offering if folks truly see a need!

Hey Dan, I will have to check out your product! We should also chat about how your amp works with our kits, I would like to hear more. Thanks for your business and for buying our speakers.

In response
“Respectfully, I disagree with your statement that this is easy. For many, it has not been easy and until now not obvious.”

While there are some people that may struggle, I think I general the concept of connecting an amp or a speaker is pretty simple. Though I have encountered people whom needed additional help, I believe a person lacking the basic knowledge to connect a speaker (+/-) should probably not tackle a project like this, get some assistance from someone with the knowledge, or buy a ready made kit.

Finally, Pinball Pro speakers are built in a way to maximize the sound of a stock game, and it works very well. Plug and play, this is certainly designed for the person that wants a simple solution. Adding external power or amp of any brand will no doubt increase the volume and performance of a quality speaker such as Pinball Pro.
