Hi. I've got a Sundown SA-12 rev3, paired with a Rockford Fosgate Prime 1,200 Watt amp. Been installed in my car for years. Never once had a problem, this thing has been a tank for as long as it's been installed.
Sometime last week it just stopped thumping. I was driving and noticed there was no bass at all, except small little bumps.
I have checked the wiring from the amp to sub, amp to headunit, amp to battery. Nothing seems to be wrong or broken. The amp lights up as normal. The amp fuse is still intact.
The only thing off is my bass knob LED also doesn't light up anymore, even though the amp that it's connected to does.
I'm really lost, not super great at electrical troubleshooting, so any advice would be appreciated. Should I completely disconnect my sub from the box? I tested my battery with a multimeter and it checks out, the alternator as well seems to check out fine.
