This is the pin diagram for base commander sport stock radio.




I have a 2 channel amp so I only powered the front. cut the wires and used splices to hook the wires together. Keep the right and left + and - separated and in order.

The door speakers are hooked in parallel with the front 2.5" tweeters. Can not hear the rear speakers though they are still connected.

The stock dash speakers are tweeters.....

The amp instruction book says to hook a wire to the blue wire on the radio so it only comes on when the radio is on, but I don't know which wire to use. The hot wires are always hot....not switched....not sure where to connect.
