Looking to do some upgrades on my stereo. Anyone on the boards that has a place near Simi Valley/San Fernando Valley area? If not can someone recommend a reputable online dealer. Looking to replace 2 sets of 6.5 2-way speakers for now then after that a new deck and woofers. Was thinking MB Quart for the highs does. Like or dislikes on them? I have always liked them in cars but I'm game to try whatever.
