sme as mine, its connected to the stereo, its a waste anyway, all mine does is add more echo, leave mine on pop.
driver just points the sound to the driver, but it sounds more 'tinny' this way, and dynamic is supposed to up the volume as the speed goes up (doesnt work)
you can pull the eq out and put a cubby hole in and the stereo will still work fine
or if you want it to work, check the other end of the lead is in the stereo properly, there not a very secure fit and can come out if someones pulled on a wire
