[QUOTE="goblues38, post: 1433731, member: 29724"] The only place you can get a "full range" signal is off the rear doors. And it is only full range at low volume levels. As soon as the volume goes up, the bass management kicks in and the low frequencies roll off. This is done in the B&O amp. This is done to protect the factory speakers from constantly blowing due to lack of power (like 10 watts), and the distortion created with low frequencies and lack of power. Ford does not want people constantly having warranty claims for blown speakers. The reason you cant use the front doors, is because the B&O amp only powers the mid woofer in the door. It is crossed over in the amp. A second amp or module is under the front dash somewhere and that is what powers the tweeters in the A pillar. Put all this together, and that is why you are just burning money trying to make the B&O system sound any better then it is. replacing the speakers is pointless because the amp is where all the problems are at. In fact, get rid of the B&O amp and the factory doors actually dont sound half bad. So, your best recourse is to buy a NAV TV, Buy a 5 channel amp, buy rear 2 way speakers, buy front components, and buy some subs under or behind the rear seat. Around $2k if you can do it yourself. $3k if you need a professional. (estimates may vary). [/QUOTE]
