That will be the relays kicking in, soft start so it powers up without any thuds etc. Nowt to worry about.Need some advice should it constantly click if faulty or any sort of clicking is a sign the fault is developing? reason i ask is because my mono+ clicks twice every time i put it on then there is no more clicking works as normal.
Al the subs I have owned do it when powering up, some quieter than others.
