tacomabanga1986 Posted November 29, 2011 Report Share Posted November 29, 2011 a ground run might ease the drop hell i drop in the 12's with 1000wrms and 2 batterys with big 3 in 0guage do u have 1 run of 0guage going from front to back? maby a second run of + and a run of neg might help it a bit most 0guage is rated @ 300amps but if alt aint supplying and your pulling more current then theres not much u can do, what is your batteries resting voltage after beating on the system?

ChevyBoy95 Posted November 29, 2011 Report Share Posted November 29, 2011 you should do 2 runs of 1/0 just due to the fact depending on how long the run is you might not be getting 270 like you should. The rating on 1/0 (250-300amps) is the amount before it can start to melt and heat up really fast, that's what fuses are for. Do a second run of 1/0 and see how it goes, if you still get a big drop add another battery.

tacomabanga1986 Posted November 29, 2011 Report Share Posted November 29, 2011 http://www.powerstream.com/Wire_Size.htm Maximum amps for power transmission 1/0 150 i think your being misled, this is for ac voltage, dc voltage is much different 0guage in home wire is different from 0guage in car wire, most is aluminum, or copper coated aluminum like what is on light poles, when it means power transfer it goes by light pole to home, thats why they put 4/0 to power a home with, 200amp main with 302amp peak wire gives u some room to compensate with surges and what knot that is a different formula than what we use, this goes by air convection and heat resistance because with ac current u have alot more resistance at higher voltages so u get alot of heat and what knot, if u take a 220v drop cord and roll it up and plug it up to something, then use it for a while u can feel the heat it puts off hope this makes sence Quote here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit Link to comment Share on other sites More sharing options...

Bmike Posted November 29, 2011 Report Share Posted November 29, 2011 (edited) what brand/type of wire are you using, another run would help ,more batteries would help too, but your gonna have drop until you meet your power demand, which means you'll need another alt. any time your pulling more amps then your making your gonna have drop, no matter how much wire or batteries you have.

Wicks Posted November 29, 2011 Report Share Posted November 29, 2011 I've got experience being dinged for quoting this spec: http://www.powerstre...m/Wire_Size.htm Maximum amps for power transmission 1/0 150 These numbers are for "power transmission" in a home environment which relies on AWG and NEC rules which are VERY conservative because you're dealing with house fires if overloaded. "Power transmission" basically means an RMS continuous current for an extended amount of time. If you ran 150A through 0 gauge cable for an hour, it would get warm. Car amplifiers are fed off of DC voltage, but they do draw current mostly in pulses, unless you're playing a LOT of test tones. Since the current is pulsed DC, you can stretch that rating quite a bit. Since the wiring is in a car, there are outside air cooling abilities which aren't available if the wire was used similarly in a house wall that's insulated. The lead acid Duralast/marine batteries may be affecting the system too. Wet batteries hold a TON of charge but they can't release it as fast as an AGM battery (XS Power). Wet batteries will also have higher series resistances which will add to the drop. As stated previously, more wire runs and maybe adding or switching to AGM batteries should help. Bigger/more alternators would also help so you're not so reliant on batteries.
