Would need to kow what kind of car you have to be able to tell you but a quick way to find out is to take a AA battery and hook up the neg and positive wire from the speaker to it to see which speaker it is. If you are trying to figure out which wires from the unit are for which speakers, then take a speaker's (one that you know the location of in the vehicle) wires and hook them up to a set of wires from the unit and adjust the fade (front, back, left, right) to figure out which position those wires are for. If this doesn't help any let me know what kind of car you have and I'll see if I can help further.

Toyota vehicles have a fuse in the kick for the amp and sometimes there is located under the hood ... This is the switch turn on for the amp ... And 1 of the fuses is most likely the memory or constant power. B sure to check all fuses ... I do not have AllData pulled up . If the fuses are all good the amp or radio may be bad ... Or both ... Be sure to check all the fuses ... Many times I get clients that say allthe fuses are good and it is still the first thing I check ..Usually is a fuse ..Good Luck
