I have a JBL Subwoofer (I forget which model # because I'm at work right now), but many people have complained about this sub woofer suddenly shorting out and causing problems. I had a similar experience where some of the wires accidentally crossed and it started wigging out. (i.e The dreaded helicopter fluttering that most complained about) To avoid having the speaker on when I'm not at home, instead of turning it off, I plugged it into my receiver and it turns on whenever I turn on my receiver. That way, it only goes on when I need it (i.e. to watch DVD's). Since I am too lazy to get up and turn the volume up every time I use it, I leave it at a normal volume...when the receiver goes on (and turns on the sub) it makes a slight boom (when the power goes on)... My question is: Am I hurting the unit by doing this?? I assume it's not the best thing to do, but I figured I should really just replace the sub so if this practice eventually destroys it...no biggie. I'd rather do it this way because it's better than leaving it on and possibly having it wig out or catch on fire when I'm not home. Thoughts?
