Subwoofer prob! I think

Hey guys, I have the harmon kardon pro logic 7 system in my 54 l322 but I don't think the sub is working. How do I tell? When I put my hand on the sub I feel movement. But when I turn it up and down on the head unit it makes no difference to the sound!

Any ideas

If its only slight movement than its prob not working
It will pick up the vibrations of the other speakers and make it feel like the sub is moving.

Do you think it is just a case of replacing the sub or is it likely to be the amp? Can you add a after market sub to the existing system?

Cheers

Not too sure
I know the electrics suffer from water damage so this might be the fault

Either way, the amp for the sub is part of the sub enclosure
So will prob have to replace all if it was broken

I have fitted an aftermarket system including a sub to mine but mine is a HSE model which makes the audio system easy to upgrade as compared to the logic 7 system

Ok thanks for the replays guys! Will have it out suday and check the power to and from the amp etc
