mega problem 9prob solved by myself)

[lee1]

i.m at my wits end with this dam sub its a vibe black air active sub.
the problem is the sub rumbles constantly the only way to turn it off is to switch the headunit off.
i've had it for a bout 4 or more years it has served me well cos its been in the last three cars wired up in the same way.

can anyone help please i don't want to get another one as it was a very good sub its not too loud and it just makes music come alive .


thanks in advance.
