0 or 4 gauge

[hockey512546 10+ year member]

I need a 15ish foot run to the back that will be powering a Cerwin Vega EXL 1200D; won't be putting out any more than 800 watts from it. Wondering if 4 gauge power wire would be alright?

800 Watts/ 14.4 volts = 55.56 amps

Sound right?

4g would be fine.

8AWG would probably be just enough, but definitely go with 4AWG just to be safe. Not worth cheaping out on.

Dittos...4 gauge will do ya...never skimp on the wiring! //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

4 gauge would be okay but i would definitely go with 0 gauge you don't want to damage your electrical.

Ya i agree with every one else 4 gauge should be fine you may want to consider the future though... I you plan on upgradeing you may just want to spend the extra cash and go with 1/0 gauge. Here is a wire spec sheet for ya.

That's completely unnecessary.

Will be fine with 4g.

how so?

how so?

Because his system will be 55A; 4AWG can handle 120A-150A (Depending on the manufacturer). He could almost triple the power of his system and still be fine with the 4AWG. So why would he spend twice as much money on wire that he doesn't need?

true but u gotta take into consideration the distance he is running the wire as well as the future possibility of running more power. imo i would go 0 gauge, as i had a 700 rms amp that caused dimming and i was using 4 gauge.

It wasn't dimming due to your power wire, it was due to the charging system. I don't care what anybody says, you don't need 0AWG for 55A.
