I have an international and I've been working on putting my radio in. Got everything working, but I have a question on wiring the speakers. The trucks only have a left and right speaker connection. I wired the two rear speaker wires from the radio into the truck speakers. The front speaker wires aren't connected to anything right now. Would it help or doing nothing at all to spice the radios front and rear right speaker wires together, and the front and rear left speaker wires together, and connect that to the pair of speaker clips on the dash of the truck? The truck has four speaker, but only a left and right connection on the dash.
