I thought i seen it on here before but i cant find it. So if you can find that post put it up on this post for me. But i have a jbl 600 and 2 edk's and all of a sudden they are hitting but no sound coming out of them at all. I checked the fuses even took the sub out that wasnt hitting first because there was one hitting with sound and one not even moving. I do not have them wired in parellel just 4 ohm load. Can someone help me
