I've got 1/0 gauge wiring and if i run this along my rear deck quot;speaker wireswill this cause noise?im not talking about the RCA cables.
if its for a short distance it shouldnt, if its like the whole length of the car its possible
Since the power wires in the car carry direct current (DC), it shouldn't interfere with the speaker wires. If the wires carried AC, there could be interference.
Yes, it's ok. In fact, it wouldn't matter if it were RCA and the power wire, that's a myth. I quote, Technically, running your RCA wires and power wires shouldn't cause any problems and can be dubbed a myth. However, a lot of people will disagree. For induction between power and signal wire to occur, a form of AC (with some current) must be introduced on the DC power wire. The added signal through the power cable doesn't have enough current to do this. Alternator whine comes from poor (or damaged) filter circuits in the HU. A induction type filter to the HU is an easy cure.
