Remote Wire Amperage?

[hazardous0388 10+ year member]

quick question on my next wiring scheme:

im going to be running 8 gauge wire directly from the main battery to a "switch" then to a distribution block that will feed all of the subwoofer amplifiers. my question is what amperage switch should I purchase? 20-25 amps?

Thanks

Dustin, this is what i used when i had 4 amps in the old cavalier supermod car.

I took 4ga to that switch, then from the switch 4ga to a "ground distribution" block.. and ran 14ga from that to each amp. ground distribution block.>>>> NEW GOLD GROUND DISTRIBUTION BLOCK FOR A CAR AUDIO AMP : eBay Motors (item 230424069284 end time Feb-13-10 00:54:07 PST)
