The big 3 caused more harm then good?

Holy fack balls......

1. The alt doesn't do 240 amps...period. At idle I would bet around 70 amps tops. Hot....and 1400 rpm....maybe 150.

2. No matter what you think, or how you think......less wire is never better......PERIOD.

3. I have seen plenty of industrial electricians who can't do jack in a 12v world with a stereo. He could work for NASA building navigation circuits and not know how to properly wire a stereo.

4. Most of the guys in here gave ya the right advice....either take it or leave it. Don't argue.

Only because you did it more wrong than right

where are you checking the voltage from, is the meter at the alt the front batt or the amp?

why cant i go past page 3?

was your system louder with the added wires than the factory wires, was it the opposite? or you did you notice any change? Also what kind of batteries are you running? There's soo many other factors that may be the problem, it cant be your conclusion that defies proven science.

Something's definitely not adding up here for you either way OP, I'd get a second check somewhere else as suggested on your actual alt output under load... You are running a 2k amp, & a pretty descent one at that... I'm running a 2.5k amp on STOCK electrical without issues, my stock GM alt only does 85 amps too (On a Good day with optimum conditions to boot) lolz

Not arguing, just explaining. So if you're going to be a *****, don't respond.

I honestly do not know the brand of battery. (it is nothing special). But I do know the specs. The battery specs are CCA: 615 AH:70. I also understand that at idle the alternator will not put out a bunch of power.

That is the same question my buddy asked, but I really didn't notice it being that much louder. Also on the factory volt gauge on chevy's it reads 9 for the lowest, 14 in the middle, and 19 at the end. Mine will sit I think at about 12.5-13 when playing full blast while driving.

**** I have an idea!!! Ill make a video of me doing the install and we will see what you guys have to say!

So, exactly what I explained, but not as accurate?
The amp is always going to demand the same amount of power based on input voltage regardless of wire size. Whether it gets that or not determines output power.

Well see he didn't seem to understand your plan english so I thought I would try some even plainer english.

I did the big three myself, I would never pay someone to do such a thing lol. We used 1/0 Aluminum lugs. With 1/0 wire.

Do not use aluminum Lugs for this connection, Those are not sufficient. even if coverred, and I'm guessing they are not. Those will rust, are not sufficient conductors. Use a proper terminal loop. Solder for best connection.

You think my problems are from aluminum lugs? The only reason I used those and not copper is because they were free from Nucor Steel. Anyway I think my problem was addressed and solved early? I do not remember who but they said with the bigger wires it allows my system to pull the amps it needs. So that is way im getting bigger voltage drops and that's why I posted. But then you have other people saying that the reason you are getting bigger volt drops is because you did it wrong. lol Which one is it!!!

I'm just advising not to use the aluminum lugs, they'll work but not optimal, and over time they will not hold up.

Oh okay gotcha! I didn't want to use them, but it's hard to pass up free products. Where do you buy your copper lugs?
