Currently, I have a 4gauge wire running from the battery to a power distribution block mounted on my sub woofer enclosure. From the PDB, I have an 8gauge wire to the 1000watt amplifier. The 8 gauge wire is only 14" long. Also, I have a fuse at the battery, a fuse at the PDB and of course 3 fuses in the amplifier. Will this 8gauge wire be sufficient to run the amplifier at max capacity? Also, with the 1000watt amplifier, it is connected to 2 600watt subs, what gauge speaker wire is required to get the most out of the amp and these 2 subs? All wattages are RMS! The amp actually puts out 1015 watts RMS as the paperwork from Fosgate states.
