380 Amp chevy alternator mounted in a MK2 Jetta

[jockhater2]

Just have to finish up running 6 runs of 1/0 gauge. (3 power, 3 ground)
need 1 more battery (have 2 so far)

will be running 2 12" sundown z.3s on a 5k amp. (Exile Audio 5k)

I am surprised this isn't getting any love

[vwcrackerjack]

Sweet! Love custom DIY stuff.

Cool, but if it's true 1/0 AWG wire, 1 would have sufficed unless you are running it some crazy way around the engine bay.

Are you going to leave all them washers/spacers on there permanently, or measure it, and get something machined to have less of a chance for failure? Other than that, awesome move going with a giant alternator. Must have something big in mind if you require 380 amps.

I just did the Big 3 in mine, and my car actually runs smoother. I need to buy me a battery next.

I have a few quick questions as I am trying to learn. I see these SPL guys running multiple power and ground runs to on or two amps. Granted I know the amps like yours are huge, but what is the benefit of the multiple runs? I recently saw an adapter to run multiple 1/0 power wire into a single amp. In my cars I have never had more than one power wire running to the back and one run of ground both going to a fuse block. Asking so I can learn.

It is.

I am doing 3 runs of power. Because I will be running 5k. And want to over kill it with 1 extra run of wire.

Nope. The washers are perfect. Got lock nuts on there. So nothing is coming off.

The washers are nice because it was a tight squeeze getting those long bolts in there. I had to bend the metal under the air box.

If your looking into a 2nd battery.

XS Power batteries are on sale @ "audiosavings.com" with the promo code POWER.

I have all xs batts. A D3400, and 2 XP3000s

Good question.

The reason for multiple grounds. Is a difficult one. I am doing it because if you go to car audio competitions. Its how everyone does the set up. For every run of power wire, they have a run of ground wire.
From what I have heard, it "lessens" the resistance. But also. As everyone knows. Your ground wire is just as if not more important than your power wire.

Now. The reason for multiple runs of power wire. Is because wire has a limited rating. For instance.
KNU Concepts oversized OFC 1/0 gauge with 4,714 strands. Is rated for 350amps @ 17 feet.

Now my Exile Audio X5 draws in 500 amps of current. Which is why my amp has 2 power, and 2 ground 1/0 gauge inputs. So the amp does not get starved for power.

Now the reason you see guys have dual inputs made for the amps that only have a 1 power, ground inputs. Is because they will typically see a voltage increase of about 0.1 - 0.5 of a volt. And in SPL meterer'd competitions. Every volt counts. So they can puts the DBs up as high as possible.

Did I answer everything?

My set up is not for SPL. Mine is just my daily driver in my MK2.

That's fine, but as I said if it's true 1/0AWG wire, a short run can easily handle 350-400A. But hey, to each their own.

EDIT: Wait, I think by "runs" you were referencing wire from the battery back to the amps, I originally thought u meant from the alternator to the battery.

yes. You were confused at first. 3 runs of power/ground from the hood battery to the batteries in the trunk.

That is another reason why I am doing 3 runs. Because I already have to remove the seats/carpeting for the new runs. And cut into the firewall. So I am only doing this one time.

In that case it makes sense. You were speaking in context of the alternator so thus I was still on the alternator.

I definitely need a D3400, but I will be heading to Korea for a year in October, So that will be a purchase when I return home. I also went with Sundown, but not that much. My 2 SA-10s powered by a SAX-1200D shake the **** out of my package tray when the lows come. I couldn't imagine anything larger.

I can't either. I haven't heard a system as loud as what I am building. no one near me in wisconsin that I know has a loud one. But I am going to a audio competition in madison. So I will hear stuff that I will never achieve.
