I was reading the manual for my P200-2 amp, and it says RF recommends using 4 AWG wire for the power and ground leads. I was told by my audio techs that I could use 8 AWG. I'm confused now, because I want to power this thing right, but not go overboard. Do I need to use 4 AWG or 8 AWG? Are there drawbacks/bonuses to using a specific kind of wire (like, will the 4 AWG pull too much power from my car's battery and alternator)?
I've already checked on the amp's power draw, and RF recommends something like a 75 amp alternator to run the P200-2. My car's stock alternator is rated around 105 amps, so we're good on that front.

Id go with 8G, 4G is overkill for just that amp.
If you plan on upgrading amps, or more, 4G would be a good choice.
Also, the wire doesnt draw the current, the amp does - so you dont have to worry should you go with 4G. |

But for a 200RMS amp that may put out 300 in the end? As much as I like following the rules, some just seem to not be justified in the end for the amplifier but rather add ons.
If a P2002 needs 4G, then a P5002 would need 2G, and a P8002 would need 0G..
Ive run a P2002 and a P3002 on 8G, and it didnt fry any fuses or burn the wire so far as I could see. |

Depending on the price you can get it, remember, you can Never have to much power wire on tap. Larger wire = less internal resistance (albiet very minimal)

Price is the reason I'm asking about the wiring. I can get the 8G kit for under $60, but the 4G kit is over $100. Part of me just can't justify paying the same for the wiring that I did for the amp itself.
And bearing in mind here, the manual for the P200-2 is the same manual for all of RF's 2 channel amps.
Maybe I'll submit this question through the knowledge base, and see what RF has to say about it.

8G Kit $60 + 4G Kit over $100 = You're getting robbed!!! $40 extra for the 4G. Who are you buying from? I don't buy kits anymore. I buy my stuff separately.
From the manual:
NOTE: We recommend a 4AWG wire for use.....
I'm sure it'll run off an 8Ga wire. It'll probably run off a 16ga wire but you won't get much use out of it. |

I was looking at the kits through Best Buy's online store, cuz I got coupons. But even with my discount, the 4G kit is still over $100 (something like $110 shipped, if I remember correctly). Maybe I'll look around and see if I can find the 4G for cheaper somewhere else.

| Also if you use recommended Amp kit, save the UPC and it will automatically extend your Warranty for 1 extra year. (New equip only of course) |
