I have a Pinball Pro with no problems.Do you think it's worth the upgrade?
I have powered sub woofers on all my games. I have some Vector ones I paid $48 for and some Polk I paid Around $100 for. Both sound great, the Polk's have a little more oomph. You can also hook two games up to one sub, just hook one up to left and one to right. I use alligator clips onto the cabinet sub connectors and remove one of the coin box tee nuts to run the wires though.
The positive connection is usually the front connector on the cabinet sub.
