Yes you can...wire 2 speakers on each channel in parallel. google parallel wiring... easier to see a diagram then explain!

So is it 125 each speaker? Or will it be 60 to each after parallel? .. I just want to make sure it's not going to blow the bike up.

It will essentially be 60w per speaker.

Just a quick question. If the ARC 125.2 is 2 ohm stable, and we are dealing with 4 ohm speakers, wouldn't it be better to run them in series instead of parallel? That is currently how the installer did my 125.2? Just wondering if I should try switching this??

series would increase the ohms and cut back on the power output of the amp. More resistance.

Thanks Juice - Gosh, I'm really confused now. I thought that if you had 2 pairs of 4 ohm speakers and ran them in series, they then end up at 2 ohm?

Then with the ARC 125.2, this amp spec's at 70w @ 4 ohm or 125w @ 2 ohm, so when you go to series ending up with 2 ohm, you end up with more watt output, and overall better performance?

So you are saying that is all nonsense, and I should switch this to parallel? I was actually getting ready to upgrade to PN4.1000D to give a separate channel to each of the fairing and lowers. I wonder if changing from series to parallel is going to offer any improvement?

Thanks for your insight!

2 4ohm speakers ran in series gets you 8ohms.
2 4ohm speakers ran in parallel gets you 2ohms.
