Question
i was attempting to put a 80 watt amp to a 12 in sub in a 98 taurus but ran into problems 1. does the factory stereo have rac hook ups to make my life easier? 2. my amp has high input as well as low can i use that if q1 is no? 3. will the 80 watt amp push a 12 or not my previous answers from people have been mixed? 4.best to place amp near sub or away or d/m? a quick answer would be great as i would like to do this soon thank you  

Answer
this is for all FORD TAURUS and MERCURY SABLE  
the radio is not at front that is only the ac unit with the radio controls,
the radio is in the trunk  left side behind the carpet, there you will find, the speaker wires

if you install a hi and low, with remote, you will get 2 rca jacks and the blue wire to tun on the after marquet amplifier

use this device
