amp kit guages

[dek86]

How much power does a 4 guage and 8 gauge amp kit handle?
Thanks,
Danny

8 Gauge is usually 150-350Watts
4 Gauge is usually 350-800Watts

not true, the amount of power has nothing to do with wattage, but instead ampheres.

And the guage depends on how long the wire is...

this is what my MECP book says about it
iasca's recomended MINIMUM wire gage size

first number is current in ampheres. Second number is wire guage to use..

Also, you're gonna have about 15ft of wire, you'll have a slight voltage drop using 4 guage if you go over 16ft, I did, got 2 guage and had full voltage traveling through, now I have more power and had to switch to 1/0 guage wire with a distro block

up to 4 feet total amp draw

Most KITS have the numbers I have posted, but for more info. on car installs, wiring, etc check out www.teamrocs.com and then go to "technical" theres lots of info to check out.

LOL ohh thats funny guage is how thick the wire is not how long it is sorry i might of miss understood you but guage is thickness not feet

chevyh8r,
Yes, length has a lot to do with voltage drop. Gauge must be increased with longer runs.

member02,

Amperage and wattage are directly proportional when voltage is held constant. IxE=W And wire length really means nothing in a vehicle since all lengths would be under 20' anyway.

I was just saying guage has nothing to do with feet

I read my own post and I'm pretty sure I mistyped in some way or another, but the numbers below it are correct, I meant to say the guage is the thickness not the length, I honestly don't know how I said this...

 

[chevyh8r]

alright its coo i just diden't want to get that dude confused.

0 gauge, 00 gauge I never heard of them I thought it was supposed to be 1/0 2/0 etc...

 

[member02]

weeeeee!

00 and 2/0 are basically the same thing, the first number just dictates the number of 0's

it get's ridicuolus to a point... 4/0 which CAN be had (very expensive) is nearly 2 inches thick

I've actually found 6/0 once online... something like $30 a ft

 

[davesexplorer2]

those large cables can be found industrially, and I think very high powered welders use them too. A few SPL'ers that I know use 2/0 guage, thats a little extreme for a normal person........
