well one day i was riding down the road and the headlights started flashing and the inside lights started going off, the radio went off and my car kept shutting off. so i finally get it home and i thought it was my sub cause it wasnt hitting anymore. so i unplug the R and L plugs, the ground wire and the positive wire. come to find out it wasnt the amp or sub, the ground to the battery had a bad connection. so i relocate the ground and the car runs perfect. the next day i went to rewire the amp, i wired it all correct. i turned on the car and the sub doesnt hit at all. the amp comes on but the sub isnt working. i checked all the wires and everything looks good. i dont know what it is. the fuse to the amp is good. so can yall please help me. any suggestions are welcome.
