I am planning on upgrading my system with new amps. I am currently using 4g wire and a 150a fuse in the power line. I am wondering if i will need to upgrade my power and ground wire. I plan on purchasing 2 Planet Audio AC1500.1M amps. The amp requires 4g wire, but since i will be running two of them will i need to move to a bigger wire, and will i need a bigger fuse? or will my current wiring work. thanks in advanced
Bigger wire would be needed if running two of those amps. Run 1/0 gauge from the front then to a distribution block where you can break off into two 4 gauge wires. The ground can be done the same way. You'll want your ground to be 1/0 gauge as well.
