Question about Car Audio & Video
What dose ACC, BU, P.CON & SP. OUT stand for?
The ACC (accessory or ignition) is for the red wire which is 12 volts only when the key is on or in the accessory position
The BU (back up) is for the yellow wire that get 12 volts all the time, even with the car turned off. It keeps the memory for the clock and preset radio stations.
P. CON (power continue) is a 12 volt output for turing on your power antenna or to turn on an external amplifier.
SP. OUT (speaker output) you have 8 of these all color coded. The white and grey are the front speakers with the solid color being the positive and the black stripe is the negative
The green and purple are for the rear speakers with the solids being the positive and the black stripe being negative.
i hope this clears it up for you, let me know if you need more info. have a great day :)
