I just came back from vacation, I left the system in but not connected, I reconnected it back up and now the sub does not do anything, I connected another sub and it worked. I WAS WONDERING, how do you test a sub to see if its blown or not? I remember this one time I went to an audio store with a friends to test his sub, they tested it with a 9 volt battery I think. HOW DO YOU TEST IT?
I'd just hook it up to a home audio receiver and see how it sounds if you want a really easy way to do it. Make sure the wiring inside the box didn't get knocked loose or something like that-it sounds like a wiring problem-especially if the sub was fine before it was disconnected.
The battery trick is a polarity thing and isn't all that useful anyway.
How do you do the battery thing? ALSO is it POSSIBLE,,, all I did was disconnect the REM wire, is it possible that power from the battery could still go to the amp and fried the VC's? or something like that???
hmm. i dont know why ur sub would all of a sudden stop working. expecially if you weren't using it at all. if it was working fine before you left, and all you did was disconnect the wires, your sub wont be blown because you havent done anything to it.
i would check do the batt thing anyway
i beeive you connect the + terminal on the sub wires, and connect it to the + termianl on the batt
then do the same with the - side... neg terminal to neg batt terminal, it should make a popping sound.
Use a multimeter and make sure your sub is reading around it's specified load ( around 4 ohm for svc 4 ohm is my example )
Then, while your car is running and your deck is on, but the volume is turned OFF, check to make sure your amp is getting at least 12.0volts. Then make sure your REM wire reads something, anything is fine as long as it's at least .25 amps on the multimeter. If all of this is fine, open your sub box and make sure a wire didn't come disconnected inside of the box.
Don't hook your subs to a battery.. why take the risk? Just invest in a wise investment and get a multimeter, if you don't already have one.
