Anyone install a high-output alternator in their Z?

Really nothing, just needed ring terminals and bolted it on. My install guy actually did it, while I stood around handing him tools. lol

It's been like 3y, so I don't remember too much, really.

To obtain full control of your OEM alt you can pull the IPDM wire (regulator control)
And it will always charge at 14v and should give all the amperage.

You should try this first to test voltage drop.
The replacement Alt will most likely be a 1 wire type however if it is a 3 wire just like the factory you'll need to pull this wire or the IPDM will control the alternator and give you the same issues.

And here I was thinking I was the only one doing a serious audio build in a z

You shouldn't need to upgrade the alt with just 1k..the stock alt did well for me with 2k..I didn't have optimum voltage but I was dropping into the 11s either..I'm running like 12k watts not with a 270amp and 2 lithium batteries

You're running 12kw in a 370Z?

Do share more info, please...
