Need info before I start diggin into the dash...
OK... First off, I have an Alpine head unit that I love and want to use. The thing is I like the stock unit as well (the pioneer 290W, 5 speaker, MP3/6 disc changer system). But it does not play WMA's. The Alpine does. Now, the stock speakers are upgraded Pioneer coax's all the way around so I won't have to replace those. And the sub in the center console hits pretty descently as well. What I'm tryin to figure out is if the sub is powered by a separate amp or off the head unit. If it has a separate amp, how is it connected to the head unit (i.e. pre-amps or speaker level or some concoction that Ford came up with)? My Alpine has 3 sets of pre-amps, one set being for sub control. Would I be able to use that for the stock Sub?
Now, if I decide to go ahead and switch to the Alpine any way, will I still have a working sub? Will a regular wiring harness form Walmart/circuit city/best buy work for this particular application?
