If you see your question here go to the link at the bottom relating to the section you are needing to view for the answer. I have spent many years in car audio as an installer and an owner of car audio stores as well as the electronics engineering/technician field and i personally know some of the folks that contributed to this FAQ. The best of the best have put together an all out full scale faq to answer anything you need to know about car audio.
