I already have an aftermarket radio/DVD player installed. It plays low as if the factory amp is not bypassed. How do I do this myself? I found the two plugs leading from the factory amp. One is with the amp and the other is with the amp bypassed (from what I was told). FIRST QUESTION: Which plug is with the amp bypassed? The one with less wires coming from it? How would I connect the plug with the amp bypassed to my aftermarket radio? My radio currently is connected to the plug that matches the plug "with the amp". How would I conect i to the plug that bypasses the amp because they can't plugged into the same connector. Please Help!
