Does a 1999 Ford Expedition Eddie Bauer stereo have RCA pre-outs?
this series of expedition eddie bauers all come with a powered head unit. This means the amp is built into the radio. However it does have a subwoofer built in the rear passenger side panel by the third row seat with an independent amp for this sub mounted right in front of the sub. If u are trying to ad an amp and bigger subs without replacing the factory head unit, it is very simple. But I would recomend replacing the radio. The factory speakers sound great with a good radio and the upgraded subs will work great also. When installing subs and an amp with the factory radio, simply cut the wires going from the factory amp to the factory sub. Then wire in a ” high to low level converter” which is available cheepest at any walmart with a wiring diagram. This converter will have RCA outputs. Or u can run the wires from the factory amp to high level inputs on your upgraded amp IF it is a mono block amp or will run on one channel inputs (refer to manual for amp) while in bridged mode.
