yeah, most head units are only meant for 4 ohm speakers because of
various factors including the heat dissipation limit from the head
unit itself. If you use a 2 ohm speaker on a head unit, you are
drawing more power for the speaker and at the same time more power
dissipates from the head unit itself. If you have too much heat, ka
boom! You short a connection out or you create an open circuit
somewhere in the head unit, which both are bad... There goes your
head unit and your warranty will not cover it because of improper
installation.

If it were me... I would buy the MegaVoxes. Cheap price but a lot of
clear sound... but you most definitely need an amp for those things.
I wonder what they sound like with 20 Watts per speaker. Probably
very little sound.

2ohm is a scame....
its just a different measurement of the same power.lol
its like 4quarts vs 1gallon.lol
4 is bigger than 1. but its =.
the best 6x9 ever made. jvc, 6x9. 120rms. 92s/n. 3way. 27-23hz.
but top kenwoods are close.

dude... did i say you were incorrect? For all i know you probably
know a lot more than I do. I was elaborating on what you said and was
discrediting Bob Wald for what he had said. When I said, "If you
don't know electronics"... I meant you as in general to all people who
don't know electronics.

well i my not know electronics but i know you cant magicly wire a amp to
get double the power. with no more draw from your battery.lol!
