Distributer accessory box blown?

Had my speakers, amp, and my light bar wired to the box in the front. Worked fine for a day of riding. Next day, it was on for 5 minutes and both of them quit. I’m sure I had too many amps running to it but the accessory fuse under the seat isn’t blown? Did I burn a wire to it? That’s the only thing I can think of. It doesn’t have a hot to it anymore.
