Just curious, but are there any differences between 2Ohm vs 4Ohm speakers, besides power?

 

Resistance, best to match your speaker to your Amp rating. High quality 4 ohm amps will say 2 ohm stable.
There is a possibility of burning out a 4 ohm amp with 2 ohm speakers.

 

There's a sticky explaining all that and more. Some way beyond my brain to comprehend. lol But good info to read and refer back to.

 

For the sake of simplicity, look at it this way.

8 Ohm & 4 Ohm speakers are most common. H-D uses a 2 Ohm variety.

If you connect 4 Ohm speakers in place of your factory 2 Ohm speakers (and no other changes), you will get 50% of the output volume with the same settings on the gear.
If you were to replace your factory 2 Ohm speakers w/ 8 Ohm speakers (and no other changes) you would get 25% of the output volume with the same settings on the gear.

This is how/why just buying a nice pair of typical speakers isn't enough of an upgrade to an HD audio system... it will require an amp and/or head unit swap as well.

Conversely, if you replace 8 Ohm speakers with ones that have either 4 Ohm or 2 Ohm (and no other changes), the output volume will increase by the same factor as above.

 

I've read that sticky. So then as I understand it, there is no sound quality difference between using 2Ohm or 4Ohm speakers. It's just a power/resistance thing. Less resistance equals more power going to the speaker, but not better sound quality.

 

That is correct.

 

 

I put 2ohm 6x9s in my bags and it makes a huge difference. I can finally hear them at 75 plus...
