Subwoofers
Sub's impedance magically dropped. Need help!

[QUOTE="45auto, post: 1582028, member: 565565"] Ok, so this is what happened. I'm riding along, I get mad at my girlfriend, so to tune her out, I set the bass level to max, and crank the HU to 80% to tune her out, subs are hitting hard and then a few minutes later the subs turn off, I figure the amp went into protection, I figure wrong, it never comes back on, I drop the girlfriend off and inspect... The amp blew a fuse, so I just replace it, turn the music on, the fuse blows a few seconds later, I figure there's another problem, so I pull out the multimeter, and the impedance of the subs is now 2.6 ohm's as opposed to the 3.8 ohm's it was initially installed with. I figure a wire came loose or something, but nope, nothing is loose, but I still took everything apart and checked the impedance of the individual voice coils, and they all read out about 3.6 ohms. I hook it back up, made sure everything was secure, and I check the overall impedance, and I still get, 2.6 ohms. The subs seem to be fine, I had no magic smoke or smell, and the cones move fine, so I don't believe anything has blown, plus the voice coils are reading out right. What's going on? [/QUOTE]
