What guage wire?

Ok....I got everything I need and ready to get installing except for my wires, ect.  I got a pyramid 1000 watt amp.  I am replacing my current speakers with new ones.  What all do I need now?  And What guage wire should I get?  No where in my manual did it say anything about what size to use.  Thanks for your input.

if you're only wiring one amp at 1000 watts then a 4 gauge would be fine. unless you plan on upgrading in the future. 

everything you need piece by piece:

1 battery terminator, 1 fuseholder, fuses (get a couple extra), grommit to seal the hole in the fire wall, power rings for a secure connection,4 gauge ground and power wire, fused distro block(if you plan on adding another amp) incleded in most wire kit's

speaker wire, speaker connector's, a 1 farad cap(if you want it to run smooth), Rca's

Match your ground to your power wire. Make sure you use a central grounding configuration as well.

It is important that the ground wire is the same as the power wire.

Think of it this way since the ground completes the electrical connection... If you have 2 bottles of water, one 1 oz and one 2 oz, then obviously you couldn't put all 2 ounces of water from the 2 oz bottle into the 1 oz bottle. 

The same thing happens when you use a 4 gauge power wire and only an 8 gauge ground (remember that when gauges are concerned, the lower the number the larger the diameter of the cable). Think of the 4 gauge wire as the 2 oz bottle, and the 8 gauge wire as the 1 oz bottle.

I have always been told that you always want to make sure that your ground and power wires are the same gauge, like Velocity said before.  You could use two eight gauge grounds as well (equilivant to a 4 gauge).
