[ya it is a classic]

oh haha i get what your asking. i just spent like 10 minutes writing up a complete car stereo write up. i thought you meant car amplifier but your talking about amperage. just use a bigger wire. if im reading this correct you have 3 10 gauge wires that your are going to twist together thus making it like a 3 gauge? i dont know jame you need to rephrase your question
