HELP my amp doesnt work anymore

[Vandenbusschebr]

So i have been playing out of a crate bxh 220 head and it just stopped working today. It still turns on and will recognize a signal coming in from the bass but it will only produce the quietest quietest sound. I have tried other bass guitars and it's the same issue. I have tried adjusting the connection cable and it doesnt do anything. The amp is rated at 220 W @ 4ohms and i have a 15" 4 ohm cab i have been playing out of. PLEASE any suggestions as to where maybe faulty wiring has occurred or anything.

thanks.

have you tried plugging your amp into different cab?

problems occur with various things..

In rough order of most to least likely.....

Cables (instrument and speaker)
speaker problem
bad/broken solder in amp
actual failed components in amp.
