what does ohms and db mean?

If that same amp can handle a 1 ohm load, it will give you even more power but that power is dirty. Which mean that your sound quality will go down. It might be very loud, but it won't have the same sound quality.

I would take a 800w @ 4 ohm amp over a 800w@ 2 ohm amp, because your sound will be better. It will cost a lot more to buy a amp that puts out a lot of power at 4 ohms than one that puts out the same power at 2 ohms.

Exactly right. Ohms are just ONE factor to consider when looking at audio quality. Why have a 2 Ohm speaker that blares a bunch of noise along with the audio signal?

Again, I'm not trying to say that lower is absolutely better, just that it can be a factor that a novice can use as an indicator................GENERALLY.
