Have a ARC Audio 2 channel amp that's 70x2 at 4ohm and 125x2 at 2ohm...I have 4 4ohm 6.5 speakers..can I run all 4 on this amp?

 

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.

 

Easy stuff, you got this

 

Got to be better then to 20w my radio puts out.im running a hd1bt Jensen radio.2 nvx 6.5 in fairing. 2 db+ 6.5 in tour pods.and hogtunes Tweeter pod..

 

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.
