I just put a new head unit in my explorer and i noticed that the the remote power wire on the back of my head unit had to be hooked up to the blue wire on the harness in order for my speakers to work. i take it that there is a factory amp installed already, will this have any effect on a aftermarket amp that i am wanting to install for a subwoofer?.... also any suggustions on what watt amp would work the best? Thanks
i believe that yours prolly has the same amp that mine had...it was in the back on the right side just above the tire well....real pain in the neck to get too
my speakers with the hu and stock amp went crazy...got loud at volume lvl 10 when the hu went up to 50....speakers died real quick lol...i believe they do make harnesses to bypass the stock amp
i went the hard way and ran new wires for all the speakers.
Wes post what all your wanting to do so we can give you suggestions, are you wanting to amp your speakers? what kind of subs are you thinking of? Whats your buget/ how much space are you willing to give up to sub(s) are you want sq/spl/sql?
