The speaker Mineral Insulated Cable should then be installed. This is a twin run of unshielded wire, may most likely quite deep. The power that will be seemed to drive the speakers will determine the required gauge of cable. When wiring up any speakers make sure they are wired right round or if you will invert the phase which could cause cancellation and a reduction in sound at certain frequencies. By this I mean make confident that positive gets to positive and negative to negative for any speakers. If you are just wiring one subwoofer then this isn't as critical as you'll be able to usually invert the phase using the amplifier may solve difficulty.
OK, so you've all of the wiring in hand, capable to go. The time has come to disassemble parts of one's vehicle. First, figure out where your wires is run. It's my job to run my Power wire about the same side of your vehicle as the battery. In addition usually run my RCA cables along the center of this vehicle.
