dB sub12 fault

[Daffyduxxx]

Hi,
I am in a 5 piece band and we use a pair of dB sub12 active subs. Last night one of them has gone extremely quiet compared to the other. Tried different cables still the same. If we turned the volume to full you could just about hear it.
Could anyone suggest what might be the fault, and is it somethng we could fix ourselves i.e blown fuse or component etc.
many thanks for any hell you can give.
Paul

It most certainly is not something the average Joe can repair simply.

Thanks Jazz, that's a bummer.

As there are not any readily available schematics for that particular Sub, you will need a good tech simply to diagnose it.
