While this is nice, What we use the most is the main game volume kill switch that Pinnovators has.
This will be a hassle if I have to open the coin door every time to turn down the exterior game volume every time and then back up again.
I sure hope Pinnovators is still allowed to make their own version like they did for SAM games.

Edit.... I sent Pinnovators an email asking if they were still going to be able to make their own? We shall see.

Thanks. I did not get any response from my email to them.
I have talked with them in the past and got two different stories.
1. We can't do Spike 2 at this time.
2. We are actively working on it.

As all my games have Pinnovators headphone jacks with Subwoofer output as well, I really miss not having it on my Aerosmith.

Who is Mark and why does he not want my Aerosmith to have your great products?

I have had no problem with the $100 cost from Pinnovators, but you do also get dedicated sub woofer output jack as well which is awesome.

I am a true believer in the sub adapter. It is a great product.
Still waiting on headphone jack system for my Aerosmith though.
Not buying Sterns if there is even a slight chance of Pinnovators getting one done.

I agree.
Looks as simple as it gets with off the shelf parts.
