Jamma cabinet how do i hook up stereo sound?

Pages: << < (3/5) > >>

TrAb:

Im now thinking about installing a pair of computer speakers of some kind, the speakers that are in the cabinet are acually pretty ---smurfy--- :(

Kevin Mullins:

Ok..... once I saved your pics I could read the amp labeling a little clearer.

The two little connectors on the right side that only has two wires each are clearly labeled SPK1 and SPK2. (Red/Black wires, White/Black wires)
So those should be the outputs going directly to the speakers themselves.

The Red/White wires on the larger connector should be coming from the volume control.

Now what you need to know is what else leads INTO the volume control ?

The input and output of the volume control are on that CN2 connector by the volume knob.
L_OUT and R_OUT should be the Red/White wires.
You need to find the wires that go to the L_IN and R_IN and then follow those to where they come from and show us what you have there.


Did this cabinet come with a game installed in it or is just just sold as a basic JAMMA cabinet?

TrAb:

Its was just sold as basic jamma cab no game. I took the speaker covers off last night and there is only one regular speaker in each side, there is a hole and wires for a tweeter but it was never installed? I looked at those wires and they are the same red/white in color and i believe that lead to the jamma harness?

TrAb:

Im going to get a voltage tester and see what its getting exactly tonight. Maybe its not getting enough power?

Just on the JAMMA harness there will be only two wires for audio.....
One is the + (pin 10 on the parts side)
One is the - (pin L on the solder side)
(this is mono)

So if you are trying to connect RCA style cables into that then the shield for both cables will go to the - wire ....... and the main conductor for both cables will go to the + wire.

But you need to verify exactly how the cabinet is wired FROM the amp TO the JAMMA harness first.
Since it appears to be a stereo amp, but JAMMA is mono..... I would think that the two Red/White wires going from the amp to the JAMMA harness would be tied together somewhere. This is what I'm trying to verify.
