Hey I haven't posted here before and I was hoping you guys could help me figure this problem out. I have a 8" punch HX2 running off the rear 2 channels of my punch 800a4. Well the other day it just stopped playing. It had done this before but it always turned back on. I changed the rcas because the ones I was using were about 2-3 years old. Still nothing. The power is fine and the fuse isn't blown, the ground is also good. I tried putting it on the front 2 channels and still nothing. I've changed the connections on the rcas on the head unit (connected it to the sub out put, front and back out puts). The wireing on the sub is solid and the sub isn't blown (it still feels like it did when I bought it). And all of the settings on the HU are the same as they have always been. Please HELP!!!!!!!
