2 runs of 4awg power wire = to 1/0 ??

[cbrrocketrdr 10+ year member]

Since I have no money for a 1/0 kit but I want sufficient wire to support each amp and I have 3 full runs of 4g....Can I just run a run of 4g power from the battery to the back to each amp...and that'll basically be the same as running 1 line of 1/0 to a distro block to 4g out?

(3) 4 gauge will be a tad bigger than 1/0 gauge.

so each 4g run sufficient for an 800rms x 1 @ 2ohm sub amp and a 200rms x2 4ohm speaker amp?

yes but dont forget now you need 3 fuses up front so you dont burn your car to the ground //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

ill have a 1.5 farad cap (yes i know caps dont do shit, but it's there and it'll tell me the voltage) on the sub run...and a yellowtop up front

how (3) fuses....i'm doing 2 4awg runs from the battery and yes they each have a fuse block...sub will have 100amp and speaker run will have 60amp fuse..

Every 3 sizes = nearly double the size iirc

...ok soo back to my question i ONLY have 2 runs...where, how and why 3 fuses in only 2 runs??

forget comparing to 1/0G bc the question was answered that a 4g run to each amps RMS ratings would be suffiicient...im just lost on how or why you would be 3 fuse blocks....

I think he was refeering to where you said you have enough wire for 3 runs of 4 g.

 

[cbrrocketrdr 10+ year member]

ohh ok so then all in all im alright with what i have?

100amp fuse on 1 4g run to 800rms and

60amp fuse on 1 4g run to 200rmsx2 amp...

Depends, is that fuse block gonna be located 18 inches from the battery?

 

[cbrrocketrdr 10+ year member]

no ill have both blocks within 12inches from the battery and the cap on the sub run less than 6inches from the sub amp

 

[SocMunky 10+ year member]

well then yeah, I see nothing wrong with that then, other than having to run two sets of wire. Out of curiosity, how much more will it cost you to do one run of 0 gauge or so over the cost of 2 runs of 4 gauge? From what I understood you have not bought the wire yet?

no i have....i have 3 full Rockford 4awg wiring kits....and no i didn't spend a dime on them

reason for all this is bc i wanna make sure even the 4g for each amp would be sufficient otherwise id get rid of 2 and get a 1/0 kit...i wasnt sure if the sub amp would be borderline with say almost a 2g kit at least
