OK now we have most of the wires in place, we can wire up the amp.
Connect the power cable from the battery into the spot on the amp that has one of the following markings (do not connect it to the speaker positive):
Connect the 16 to 18 gauge wire into the spot that says:
Connect the 3 foot, 10 gauge wire to the one marked (do not connect it to the speaker negative):
Connect the other end of the ground wire to a nearby bolt that connects to the body of the car.
Connect the speaker wire to the + and - marked for speakers on the amp. There may be 2 channels. If there are 2 channels and you can bridge your amp, do it. I won't explain bridging but its easy and you can Google
Connect the other end of the speaker wire to the + and - on the speaker box. Try to make sure that the + from the amp is connected to the + on the speaker, and the same with the -.
