Hey folks. I'm here to learn more about car audio. I've got a 2006 MINI Cooper S that has a piss poor OEM system and a lot of road noise. I've decided I will do sound deadening and audio system improvement. I have a handle on what I am going to do for the deadening, but the audio part is a maze right now. An item that would help me immediately is recommendations for shops to listen to speakers in the Southern California area. Thanks for your help. Paul
