How bad will this hurt my electrical?

[chapo123]

its a 04 mercedes c230k. has a 120amp alt stock, with stock batt up front and a run of 4 gauge to the back batt which is a hc800 and 0 gauge from the back batt to the amp. its a t1000.1bd that i will be wiring at 1 ohm for 1639rms lol (birthsheet says so i was surprised too) and its going to be powering 2 12 lvl 3 dc's in a ported box. will it be that bad? and no i dont have the big 3 done. is it gonna be alot of voltage drop?

[cubs_fan0718]

U need to put 0ga from the front batt to the back batt IMO. yes ur gonna have some drop, how much i dont really know but it might not be much. I say run 0ga from front to back and when u get time 0ga BIG 3. The thing really is and someone might be able to answer it, are you gonna have enough elctric flow to keep that back batt happy without hurting it.

as well as the run of 4 gauge from the front to back. you are gonna get mucho dimming.

upgrade the grounds throughout and you'll be in decent shape

[chapo123]

the grounds are sanded down, im just hoping to get atleast 1200rms! the subs are 600rms so thats why lol you think ill get atleast that much?

ied take out the 4guage and add it to a big 3 for now, i think most stock auto's have 4guage anyways, my truck had less than 10guage ecept for alt to battery

i got a big 3 in 0guage and it helps with current flow, but doesnt help with voltage that much, mine stayed the same a lil bit with voltage drop and what knot but with the extra current flow it got louder

ied run 0guage from front to back, use that 4guage for temp big 3, and u should be good for now

i got a 950amp front battery, 800amp rear battery, big 3 in 0guage, 0guage from front to back, sanded down ground spot, and with a 1000rms @1ohm amp wired to 2ohm i still get dash light dimming every once in a while, and im running a 300w 2ch too

ied try this first, i kno rockfords make hella power but it takes power to make power too

[chapo123]

to be honost im scared to do the big 3 in this car lol, benz are so idk how to explain i dont really mind light/dash dimming.. i just hope i dont go any lower then 12.9... i never bump at idle or with car off. and i dont have a mids or highs amp so its just the t1000. and as for upgrading the 4 gauge, i just bought that wire lol so its prob gonna stay for a while.

[InfiniteRuckus]

there's no reason to be afraid of the big 3. it only allows the electricity to low more freely

[chapo123]

im not scared to do it, like in my sebring i just havent had time to do it in that car, but idk benz are just idk how to describe it

[tacomabanga1986]

i think 4guage is good for 1000w but ppl just run 0guage cause they kno there gunna upgrade afterward

my voltage drop is from 14.4-13.8, thats as much voltage drop as i get, never goes lower than 13.8, even at 1ohm wasnt lower than that

you should be good with what u got, you could wire the subs to a higher ohm load to see what kinda voltage drop that gives u and if it aint that much u could try to drop it to 1ohm n see what it sounds like

i had a mtx 500d 2ohm stable amp with a stinger 1f cap on 4guage wired to 1ohm with 2 15's and with my headlights on and on bright (the car was a 93 accord with 4 bulbs, i think 55w low beam and 100w high beams) at idle my voltage drop was 14.5v with no other electrical upgrades, i unno how tho

shit was mad wangin, i was useing 10guage speaker wire tho, and no mids n highs amp, and this amp does 775wrms @2ohm with 14.4v so i was doin a lil around 1000 i guess on 2 mtx 4500 1544's, lol around 400-500rms somewhat clipped goin to 2 250w rms subs lol

i think u will be fine bro, ied wire it to 4ohm if ur useing dual 4 subs and see what kinda drop you get, and if its not that bad try 1ohm n see what happins
