Easier said than done. Modern (ish) BMW are really picky when it comes to their systems especially on the electric side. I still haven’t figured out how to run a second battery without the whole car screaming.That amp should work, you need to add an 2nd battery and isolator you good to go.
That ground zero is likely their higher quality Korean built offering. You would want to purchase dual 4 ohm woofers so that you could wire them up to a 1 ohm load to that amplifier. If the price tag doesn't scare you that would be more reliable and abuse tolerant than the full bridge one I mentioned.I found this amp from Ground Zero : https://www.crowncustomscaraudio.co.uk/products/gzia-1-1500d-iridium-mono-amplifier
Lets put to the side the price, what does it mean by output power for 1Ω and 2Ω ?
And another cheap amp I found at a big auto store in UK is this: https://www.halfords.com/technology...el-1500w-bridgeable-car-amplifier-626430.html with a RMS power of 170W but 1500W peak, which I don't understand how that goes to be honest.
That's good to hear, at least I can get this off my chest, though the spec sheet shows power values of 1800-2000W which I don't actually understand what they fully mean, but I guess if I don't turn it up it won't draw maximum power. I will upgrade the charging system eventually since I'll be adding aftermarket accessories.1200-1500W amplifier should be OK on factory charging system.
The 10'' subs I have are rated at 2x 2ohms each, won't I be able to wire them to that GZIA 1.2000D?That ground zero is likely their higher quality Korean built offering.

It is very probable that 4 channel is lying about its output power (what else are they lying about?) I would avoid. It may be something you would consider to power your door speakers but generally you will want a mono amplifier to run subwoofers.
This is true. For around 10$ you can buy a simple LED voltage display so that you can keep an eye on how your charging system is keeping up as you go. You may not be able to go all out for very long at one go depending on what sort of music you use and some other factors over which you'll have no control.I guess if I don't turn it up it won't draw maximum power.

The whole dual 2 ohm woofer thing is a bit worrying though. Your impedance options there are 0.5 ohm or 2 ohm. Few options exist for either. I suspect B2, Alphard, or Ground Zero sell an amp that's the same board as the old Sundown SAZ1500D (which should function at .5 ohm) but I don't think any of those brands are going to warranty half ohm operation, and for good reason, it is very torturous on semiconductors.
Only option I see that is readily available in UK market that makes rated power at 2 ohm would be the Kicker 1200.1
1200W x 1 @ 1Ω – 14.4V1200W x 1 @ 2Ω – 14.4V600W x 1 @ 4Ω – 14.4V The CXA1200.1 Mono Amplifier is built for affordable power and performance, thanks to an optimized circuit layout and the high-grade internal components. This mono CX-Series Amp is now one-ohm stable, giving you even more wiring...www.crowncustomscaraudio.co.uk
I've had good results in the past running previous generations of their 1200W amps, they've been known to make solid reliable amps that will perform as advertised for a long time.
If it's not too late to get dual 4 ohm subs that'll give you a lot more choices, otherwise, I don't know as you're going to do better than the Kicker to get 1200W into 2 ohms. If all else fails see if you can call up one of those dealers and ask him if they have anything that'll get you 1200-1500W into either .5 or 2 ohm.
They had some for cheap on one of those sites you linked so that won't be an issue.Yeah, I've seen voltage displays on all my friends' cars with subs in them, will definitely get one of those.

I certainly can't read Romanian, but any of those woofers should have dual 2 ohm and dual 4 ohm coil options. Have you confirmed yours are the dual 2 ohm? If so you should try to exchange them for the dual 4 ohm, otherwise that Kicker amp will make 1200W into the pair of dual 2 ohm woofers and would be a simple solution if you're not married to the idea of some other amp.
You have the dual 2 ohm coils. You must exchange them for dual 4 ohm model or go with an amp like the kicker which is rated to make its power into 2 ohm final load.I don't really mind what amp I'll get, even though I would have loved to have everything from the same brand, but the amp won't be visible anyway.
I got this snippen from the spec sheet of the subs I have, not really sure what to look for since it shows the Impedance at 2 x 2 ohms and Re (which I don't know what it means) at 3.86 ohms:

And translating the specs from that Romanian website, the last line says: "It is equipped with 2 coils, which can be connected in 4 Ohm or 1 Ohm; "
You have the dual 2 ohm coils. You must exchange them for dual 4 ohm model or go with an amp like the kicker which is rated to make its power into 2 ohm final load.
If you're OK with the price that would be a good match. If you ever buy dual 4 ohm subs and an additional battery and/or more powerful alternator later it will give you more power. That amp will only make 1200W into the subs you have if you wire them to 2 ohm so into your subs that will be good for you.However, I found an amp from GZ with 1300W stable at 2 ohms called GZIA 1.2000D, but with a power of 2000W, will this still work on stock battery and alternator?
