When are subwoofers considered blow, because one of my friends has a 12" Alpine 4 ohm sub, and when tested it reads 4.6 ohms. Is this sub blown or does it still have some life left in it?

That sounds normal to me. A sub woofer is "blown" when it quits working, or if it starts making strange rubbing sounds while it's working. Or, while not technically "blown" per se, when you jab a screwdriver through the cone eight or nine times. The last works best with Audiobahn or Sony sub woofers. ------------- Support the12volt.com

if reading it with a meter, it will read 0 ohms if blown.

Not always. Could be open which will read "OL" or infinite, could read normal resistance but the VC could be broken and rubbing mechanically. ------------- Support the12volt.com

if the woofer is blown you'll hear a more of a humming sound. it definitely shouldn't be playing the deep notes too well either. there will be a lot of distortion and weird noises to go along with it.

That's my opinion. Take it, leave it, or correct me.

a blown sub will not read an ohm load... hooking a blown sub up to a meter will not show any resistance.
