The section likely says nothing at all about woofers or aftermarket speakers. if the officer was more than X feet away and heard the music, that is a prima facie violation. You can argue that he was never more than distance, but you'll lose ... unless he was closer than that from the moment you turned on the stereo you either approached him with the music on or pulled away. He does not NEED a measuring device and CAN estimate the distance. You can go into court and argue that he did not hear it and he lied, but then you're going to be faced with the question as to why the officer keyed on you if he did NOT hear it.
Anyway, you do have a right to contest the citation, Go for it.
