I was told today that 2 ohm has a higher distortion ratio than 4 ohm, is this true?

I'm beginning to re-think the entire system now. Guess it's not as easy as I thought!

Yes it is but 99% of people couldn't tell the difference by ear. Just about every sub install I have done was 1ohm the rest depended on the equipment wanted, but IMO ya shouldn't worry about SQ in a vehicles a lot is far from an ideal platform for such stuff.

heres my setup, nothing fancy but works good and sounds realy good all around sound.
