wiring jamma speakers....

[pharoah007]

I am wiring up a GT 2005 I am building and have a question about the speakers...

The jamma harness only has ONE speaker - and ONE speaker +.......I have 2 speakers

Can I wire the Neg and Pos speaker wires to the 1st speaker...and them jumper to the 2nd speaker from there???   or is a no no as it will increase the ohms (?)

I have it jumped to the 2ns speaker right now....but I will not throw the switch until I get a response to be sure.


Thanks all.

speaker terminals L and 10 are standard for 1 speaker, but you should be able to hook up another at position M and 11 (parts side - and solder side +)

the factory golden tee cabinets have 2 speakers with separate wires (not jumped as you say)

Humm, the GT manual only shows 1 set of speaker wires in the pinout???

Will it break anything "jumped" to 2 speakers like I have it?

 If the original speaker is 8 ohms, you could replace it with 2 - 4 ohm speakers in series...

 Board positive --------(+)speaker1(-)---(+)speaker2(-)----------board negative

 That way its still 8 ohms.


EDIT:

don't look at the Big Buck World kit manual then.... it full of errors. If you follow the jamma pinout they supplied in the book you'll fry your power supply in the computer and the I/O board. how hard is it to copy and paste?!

big buck world kit manual?? huh.... I am confused.   

Cut and paste?

This may help.....


looks like I have the speakers hooked up in Series.

I have unhooked 1 for now to be sure. I sure would like to use both of them.

Here is a pic from the Golden Tee manual, It showed the speakers in Series.....but it does not show the wires coming from the JAMMA harness...weird.

I labeled the pic...

1 = the speakers

2 = some 3 prong connectors I can not identify.

3 = terminals labled as U43 pin5 and u43 pin 7

I find it strange that the JAMMA connector is not in this diagram.

My setup....wires form JAMMA connector go straight to the speakers.

your photo isn't working.

but i had to repair a GT complete machine today and the speakers are indeed just in parallel on the single channel 

so just attach your + of one speaker onto the + of the other speaker. same with the -'s

Right on, thanks man.

That is indeed how I have my speakers wired.

Thanks again for the help.
