What gage of power wire should i use to wire my amp?

Question

The max watts is 1800. At 4 ohms its 500 RMS. Should i use 8 or 4 gage?

Answer 1

Its always good to use the biggest wire gauge you amp will accept. Go with the 4gauge

Answer 2

4 gauge with a 100 amp fuse and a 1 farad capacitor would be a big help when it comes to supplying power.

Answer 3

if this is the kenwood 9103D or 9104D run a 4 gauge. I have the 9103D with a 4 gauge power wire. Runnin at 2 ohms for 900W RMS. I ran a 12 gauge power wire at once becuase i was broke, and it blew the fuse quickly. haha. Im using a 100 Amp fuse with a 4 gauge wire.

Answer 4

Get the biggest you can. 4 gauge or bigger. If you lay the groundwork right the first time, you won't have to rip out the interior of your car when you want to upgrade the amp.

Answer 5

GO WITH THE 4 GA ON A 100AMP FUSE.
