Aftermarket alternator

Does anyone know where I can get an high output alternator for a 2020 530i 2L?
Maybe JS Alternators though they don't list a 530i specifically. That engine comes in a 430i. I would check to see if it is the same part number from BMW. If so, they have some really high output alternators for the 2.0L in the 430i.

These guys are top-notch.

Just input the info on this page, online, and they will get right back to you with the options that will work - really good customer service and pricing that is also very good.


I don't see what is driving this need, system-wise.

Whey are you of the mind that you need a HO Alt?

Yea I tried asking about that because I know that have the same motor but they kept telling me something was different about them.

I wanna put a 2000w rms subwoofer in with a 3200w amp do you not think I need a HO alternator?

No, I don't.

Using the stock electrical system, adding a 2nd battery to help the primary should suffice. I have a potential 3.5k to 4.5k system, on a stock 110A alt, utilizing a GloweVoltage Series 1 lithium setup, never bats an eye.

Here are three options that will handle what you're trying to accomplish.

GloweVoltage series 1, 2.


Currently out of stock, but they run out regularly, so email them to see if you can pre-order.

These two are quite good, and the 2nd one listed has all the distribution facilities built in.

S-5 $499


Another of that series, the S6, is a great open-box buy $494.00.


The PWR-S5 is the one with all the built-in wire distribution $600


Least expensive option $399


It's not all about the potential amperage draw; it's more about real-world, daily driver draw on steroids, if you will. Watch this video on what to expect, and then see if you think that Limitless is going to serve your needs.



It's not a difficult upgrade, and I have wiring diagrams to boot.

This is the basic idea, I'd be happy to draw one up specific to your needs.

Okay, thank you for the information I'll use this when I get to setting up my system. I have an auxiliary battery in the front and my main battery is already trunk so I should just wire the extra to the main right ? Should I upgrade the other to batteries or no?

Okay, no worries.

You would run it in parallel with the 2nd battery.

Since the GloweVoltage, the Titan8s, and the Limitless all charge at virtually the same voltage as the lead acid (unselaed or sealed AGM)batteries in place already, you don't even need to use an isolater.

Okay are the wires on the right of the third batteries for ground. And power to the amp or both run to amp ? Thank you for the information also should I do the big 3 or should I be fine ?

Do your installation. Get a voltage display. A small LCD type display. See what your voltage is like. If it starts going into the 12v range then you want to start beefing up your electrical.

As Doxquzme has said, you might be surprised how well your system does on a relatively stock setup.
