Question about Ohm for speakers

Post by erzane »

Hi guys,
I would like to buy this:

but I don't know if 100 ohm is enough because mine is 500ohm (same brand: Violet Electric)

It's a potentiometer to set the volume. I don't nothing about ohms. I don't get why 500ohms for an only 8ohm speaker (my speaker is 8ohm 3W), perhaps 100ohm would be enough?
And my PSU is this one:

And since all those wires and connections are made for: crédits; speakers, counter, coin, I would like to know if I can use AWG24 instead of AWG22 for replace those wires

ok thanks

Somebody have an idea about ohm?
Or perhaps explain me how does this ohm stuff works?

I have no luck with this topic..
Is it something very complexe?

Not sure this answers your question but putting it here for future reference (I keep having to look it up)

JAMMA standard appears to be a single 4 Ohm speaker.

This means you can safely run the following on a JAMMA cab for audio:
1x 4 Ohm speaker
1x 8 Ohm speaker
2x 8 Ohm speakers in parallel (wiring one speaker to JAMMA and the other speaker to the first speaker - or both speakers to JAMMA) (total impedance 4 Ohms)
2x 4 Ohm speakers in series (wiring the positive of one speaker to JAMMA, the negative of the other speaker to JAMMA, and the empty negative & positive terminals of both speakers to each other) (total impedance 8 Ohms)
2x 16 Ohm speakers in series (wiring the positive of one speaker to JAMMA, the negative of the other speaker to JAMMA, and the empty negative & positive terminals of both speakers to each other) (total impedance 8 Ohms)

Please correct me if wrong and I'll update this :geek:

Look up the spec sheet of the board amp, there's going to be your answer.

The ohms for speakers refers to the impedance of the speakers and not the power. Generally the lower the resistance the greater the current/power.
