Title: Connecting 2 speakers to Pacman PCB
Post by: markrvp on November 11, 2005, 11:35:16 am

This topic could go in either audio or arcade miscellaneous, so I compromised and put it here.

I have a Midway cocktail cabinet with two original speakers - a 6x9 and one that is round (I'm guessing 3" or 4").

how about slicing the one wire into 2....

When you parallel or series speakers, you create a different impedance.  Series up (2) 8 ohm speakers, you've created (electronically) a 16 ohm speaker.  Parallel em, you get a 4 ohm speaker.

Go too low on the impedance, you may hurt the amp due to increased power draw.

Go too high, you lose power.

Will 16 ohms hurt the amp?  Probably not at these power levels.  I'd try wiring them in series first. 

Heck, I don't even know what the original speakers impedance is.

Forgive my wiring ignorance.  Could you verify that this diagram shows wiring in series?

Yup, thats series.
