is there anything else simple to check first b4 i rip the fooker out for good?

problem is i do like my base when thrashing metallica out when i'm driving

any help would be appertiated.

Is it an active subwfr?, if so try fuses on unit itself and inline power fuse on battery connection lead.

Could be that the drivers are blown or if the head unit has been changed the amp is not connected properly

thanks lads will have another look 2moro

I am sure I read on here somewhere that you can turn the rear door woofer off and on by pressing and holding the power button for a few seconds. Have you accidentally turner the speaker off?

If it's the standard LR sub in the back door then there are no fuses to worry about.
The sub picks up the 12v power from the head unit also the 12v for switching the amp along with the sound input signal. So have you checked your voltages at the amp.
Perhaps the amp has packed up.

Depending on the model of head unit the bass can be turned down to nil (-4 shown in the display) but I'm sure you would hve checked that.
Pressing the power button will certainly turn off the sub as it also turns off the head unit.

sounds as though the voice coil has gone,put a multi meter across the terminals to check whether theres a continuous current, if there isnt its your voice coil. on big pa equipment you can get drivers reconed but you cant on car stuff.
