Question about Jl Audio 12W7 Car Subwoofer
I have a 15'' sub-woofer that locked up and I was wondering if i could reverse polarity to unlock the sub-wooferhow do i fix if not
In theory your idea would work, however you risk damaging your amp by reversing polarity and the positive and negative wires from your head unit are low voltage so they wont provide enough current in reverse or normal polarity to free the cone of your sub. but here is something that you can try that is similar in concept.
Take a positive lead from your head unit and wire it to the negative of your sub. Now ground the positive terminal of your sub to the vehicles chassy using a wire. This creates a 12v-14v reversed polarity current that should be strong enough to (POP) the cone so to speak. hope this helps
