so wat do ya think

help me please thanks

Answer 1

4 gauge will support a true 1800watts RMS, or about 250 amps, for a distance of about 2 feet.

I would recommend at least 2ga or 1/0ga.

Also, batteries will only help to slow down voltage loss. If you amp is using more power than your alternator can produce, eventually you will deplete your available voltage and/or overwork your alternator.

You can find a graph of recommended power wire size at the link below.

Answer 2

Answer 3
