quick question on power wire ratings..

[touchdowntodd 10+ year member]

I have some 4g wire runnin from the front of my car to the back already for my air ride setup (64 galaxie convertible)...

the 2 - 450c vairs pull 40amps when both are on according to the meters..keep in mind they only run when needed, usually 2 times an hour or so for 3-4 minutes.. until i hook up the EDC lol..

so, i have the 4 gauge ALL the way to the trunk, and a dist. block that runs 8 gauge off that to each of the compressors.. overkill, but cool with me lol..

I have a MTX 2150x amp that im gonna run to my old school round solobaric 10" just to get a lil noise there.. I also have the 8g kit I had sittin around already that should be plenty for this amp (300 watts rms, but old school rating)..

how much do you guys think amp wise that the MTX will draw? 2 - 30 amp fuses are in the amp... so im thinkin 30-35 amps? or am i crazy? im not a crazy bumpin music kinda guy, volume wont really go above 60%

so... long story short... the 4gauge should be able to handle 80 amp or so draw from what i know, so can i just run 8g to the dist block for the amp? the reason I am asking is because I have the 8g sittin there, and eventually i wanna upgrade to some other audio stuff and ill run 0 gauge to the back for that alone then...

for now, amps adding up i would think i would be fine... but i know you guys are the masters...

ps - i could also run the 8g to the battery, but i wanna add another MTX amp soon (275 amp a friend has so 37.5 rms watts per channel) to run a couple front speakers, could the 8g from the battery handle the 2150x and the 275 MTX amps ok?

as you can tell, im on a BUDGET.. so sorry if it makes no sense to the guys that can just afford to run 0 gauge and call it a day

**** man... i mean i know im new.. but i searched, and read about 20 threads....

im just askin a simple question about load on a 4g wire...

i know the answer on this and every other board is "go to 0 gauge" ,. but we cant all afford to run more than we will ever need..

thanks for bumpin my topic, but a simple yes or no would have been much more benificial

0 gauge welding wire is cheap

Run the 8 gauge to the battery.

Run the amplifier on the new 8 gauge wire. When you add the 2nd amplifier, run the smaller of the two off the 4 gauge wire distro block.

You'll be fine.

Then, when you upgrade to 1/0... Rip everything out and start fresh, and do it right

I was really busy at work and i think my brain was sorta fried when I was thinkin bout this...

im thinkin im gonna go 4g or 6g to a dist. block in the back for the stereo shit only, im thinkin of gettin another old school MTX amp to run a pair of 5.25s .. something like the 275x to go with my 2150x... i like the old stuff, underrated and fun! ... even a 250x might not be bad,..

the 2150x has the preouts so i can go low filter for the sub, and it will preout the highs only for the smaller amp, atleast thats what i believe..
