So i gave a DVC sub i wasnt using to a co-worker. he told me his plans to wire each voice coil to two separate bridged channels on a 4-channel amp. i adviced him against it, but he said his father has installed stereos for over 10/15 years. His father apparantly told him that wiring the sub this way will get him the most power to the sub and will also get the best SQ out of it. Well, the next day, the co-worker calls me and tell me he blew the sub.
Was he correct wiring this way? did he just totally over power teh sub? would the sound have been "better" if the sub could handle the wattage? or was i corrent in advising him against such wiring?
It would have worked if each channel was matched in power output. power is power, doesnt really matter if its coming from 2 channels or 1, as long as its the same

If I'm reading your response correctly, I disagree.
If one channel is only producing half the power of the other it just doesn't contribute as much.
This is no different than using only one coil on a dual voice coil driver.
However, if the two channels were connected out of phase the cone wouldn't move (providing the gains were matched) which that would cause heat without any pumping action (cooling) and could toast the coil.
I'd find out what "blown" means and post back with more information for a better answer.

Umm, thats why I said if they were matched, meaning setup with a DMM meter. Its been done hundreds of times if not more throughout the years. Of course you would match the phase of both channels, is that even a question? You must not have read it correctly

I wasn't attacking you.
Just because the gains are matched or not doesn't mean anything.
If they are hooked up out of phase, reverse polarity, does.
Not knowing if they were wired correctly is, in fact, in question and is why I asked for more information as to what "blown" means.
Don't attempt to make me believe that you have never wired something incorrectly, it happens to all of us no matter how careful we think we are.

I have never wired something incorrectly, never blown or damaged a speaker or other equipment, ever. I have spent a good amount of time fixing other peoples mistakes. I have been doing installs since I was 14 years old. Thats over 16 years now. But that has nothing to do with my post in this thread and is not whats in question from the OP.
My answer about gain matching and a 4-ch being able to push a dvc sub correctly was just stating that yes, it can be done just fine, if done properly. As the OP asked if that was ok. The phase and wiring aspect really has nothing to do with just a 4-ch amp being used to power the dvc sub, phase and wiring can get messed up coming from a mono amp to a dvc sub. But yes, it should be correct. I was only commenting on that, not his wiring or how much power he was using.
wow, thanks for all the input, i never got any more info from my co-worker about how much power he was putting to the sub all i know is how he planned to wire it. Well, all in all, i get paid for his mistake. he now owes me $80 for the sub.
knuckle head blew a sub.. question.
