I am getting ready to install an on board amplifier. I am thinking of using two speakers; one 6" and one 1.5" oblong.


What is the effect of hooking them up in series vs. parallel?

What effect do ohmn ratings have on speaker sound?

Do the ohmn rating have to match? What happens if they dont?

A series circuit has one path for the electricity to travel through. The total resistance in a series circuit is the sum of the individual resistances.

A parallel circuit has more than one path for the electricity to travel through. The reciprocal of the total resistance in a parallel circuit is equal to the sum of the reciprocals of the individual resistors.


What does the mfr of the amp recommend as to the resistance of speaker?

I couldnt find the spec on the amp board. This website says either 4 or 8 ohm speaker?????


so what do you think?? series or parallel



Looks like it does not make a difference, as long as the size will fit your guitar. Either speaker 4 or 8 ohm will sound OK.

Definitely run the speakers in parallel.  Parallel will reduce the resistance in ohms in half, series doubles it.  The lower the resistance, the more output from the speakers.  It's not a powerful amp circuit, you'll appreciate the output in parallel.

Thanks. I have a slightly larger than normal box on the way. I will report back the results.
