Question What size power wire to use?

Hey all,

What size power cable should I use from the bat to my distribution block? I will either be running 1 Orion XTR 800.4 (100wx4) and 1 Audio Control amp w/epicenter @ 110x2. If I can't fix the Audio Control amp I will purchase another Orion XTR 800.4 (400wx2). I also have a Phoenix Gold EQ and Coustic 3 way xover.

I was going to run 4g and then split off to 4 runs of 8g. But now I just don't know. Maybe 0/1g with 4g going to the amps and 8g to the accessories.

The Orions have 3-20amp fuses. The Audio Control has one 30amp fuse I believe.

Any ideas? Experiences?

If you are planning to split off 4-8gauge wires from the block I would feed the block with at least 2 or 0 gauge cable. 4 gauge cable is twice the thickness of 8 gauge. 0 gauge is twice the thickness of 4 gauge.

Buy your wire from ebay. You will find amazing deals on great wire.

I think it is safe to say that 2 gauge would do you good with the setup you listed. If you end up purchasing the other Orion amp use the 0 gauge all the way back. Their amps love to pull massive amounts of current.

4 gauge should be sufficient for that amp load

My advice is to ditch the distribution block and just run 2 4ga. wires.
