If any of y'all are any good with car stereos, i think some of you are, i could use some advice as i am thoroughly confused. So my buddy gave me an old radio to replace mine that went out back in november(3 months sans radio SUCKS!!) and i wired it up, red wires to red, yellow to yellow and black to black. Nothing, checked all my contacts and my ground, still nothing.
So i called up another buddy who has installed stereos for a number of our friends and asked his advice, his advice worked but has left me confused as it contradicts all i though i knew about electronics.
What he told me to do was take both yellow wires and both red wires and twist them all together, all four! I was under the impression that one set was positive and the other negative... that being the case shouldn't this splice job have left my radio a smoking wreck?
What am i missing here? Does the ground complete the circuit?
