I was given a rockford/phosgate 60 watt 2 channel amp and a collins subwoofer box with a 8 inch JL audio sub. I installed it in my son's saturn sl1 and it worked great !!! recently the battery went dead and the car was jump started, now the sub will not work. The power fuse from the battery is good, I have power to the amp and the amp light is on, I have power to the sub and the fuse to the sub box is good, but no sound ? This is my first installation I know I may have done something wrong but have had zero trouble until the jump start. Any help out there would be great. Thanks
Tell me if you ever figure out what the problem is, this isn't the first time I've seen this happen. Most of the time it's because the head unit needs to be reset as said above, but i'd like to know if there are other things causing it.
By the way, allowing a lead acid battery to discharge completely causes permanent damage, it might need to be replaced.
