I have already run 2 power cables from battery to trunk. one was going to be for amp and the other for a powered sub. Well the wires are 8 gauge, with 60amp fuse, which was fine when run last year. A friend of mine gave me a alpine pdx-5 amp, which requires a 4 gauge wire with 60 amp fuse.
my question is can I still run the 8 ga wire (since they are both 60 amp fuses), or if not can I use both wires and tie the ends together even though they are seperate wires?
Thanks
