ASD cannot be disabled on idrive 8 yet, which is what the 2023 M3 has.

The included diagram with the Match speakers does indicate the default configuration for the BMW installation will be 4 ohms, which I know is not ideal, but at least my ears can tell the difference from a sound perspective.

The GF has a X3m40i with HK, might try either bimmer tech or bav sound in that as a comparison down the road.

2ohms woofers are for HiFi systems, 4ohms woofers are for E9x HK systems, 8ohms woofers are for F3x/G2x HK systems.

Suppose I will need to keep an eye on things then, as I do like to listen to my music loudly. 🤞

Looks like the only other 8ohm option for plug and play is bav sound. 🤔 I imagine due to the added resistance there will be a noticable decrease in sound. Is that a safe assumption?

Running the Booster (the amp that powers the woofers only) with less than 8ohms resistance will make it unstable, and could eventually fail if its current draw exceeds OEM limits for extended periods of time.

Bavsound, BimmerTech and Integral Audio offer 8ohms replacement woofers for HK systems.

Appreciate the feedback. I cannot find the speaker specifications for the integral audio woofers to confirm their resistance and the bimmtertech site says the best they get to is 7ohm.
I am a little worried trying the bavsound as they received pretty meager reviews from forum members.

IMO, add an aftermarket amp to the Match woofers that you got - an AudioControl ACM-2.300 will work without a LOC requirement with the Booster, and it will protect the Booster while making the Match woofer sound much louder and deeper.

Just as an update, the Match subwoofers sound like they handle the bass, but interesting situation unfolding in my vehicle. The drivers side seems almost like its getting little to no bass, and the passenger side seems to be getting TOO MUCH bass and the whole area is rattling. I am having crutchfield send me out a replacement set to test, but these might not be as plug and play as they suggest (also as Technic pointed out, resistance could be a factor). Just sharing so others don't have to go through what I am.

If the replacements do the same thing, I will order from BavSound and see how they compare to OEM.

Bavsound subs suck. At normal listening volumes they are much quieter than stock. So you get WAY less bass at normal volumes.

You have to be at 70% or more to actually hear them. And at that point they are louder than stock. But unless you listen to music at 70% or higher, you will loss low end bass at normal listening volume.

Now if you AMP them, then I could see a benefit. But if I was to do it again, I would just add a trunk sub and be done with it.

[dasmikechen]

Okay, embarrassed update😳😳, the Match speakers had little white spacers to use to offset the speaker from the factory grille. Did not notice this, but now I have them in there and it sounds really good again. Granted the resistance may not match so be careful, but it sounds damn good for my 2023 not having the ability to run a trunk sub!

Did you break them in for 12 hours?

Hasn’t been my experience at all swear to god I’m not sticking up for them lol. They offer a full refund, and I’ve had mine out a couple times for a warranty claim and to tighten the screws. If they were worse than or equal to stock I would’ve gotten my money back.

They do suggest some different EQ settings in case you didn’t try that. For real though, my seats vibrate and I have the bass turned down low-to-mid iirc

Yes I bought them used from another member.

I wasn't disappointed with the loudness. I was disappointed that I had to turn them WAY up to get the bass out of them. So while they are louder, they have a higher resistance which means you have to crank them up to get bass out of them. Which WAS louder than stock.

But listening to music at partial to low volume had much less bass than OEM. I dont really listen to my stereo at 65-85% volume. So for me (and a few others who had the same experience) they where not a fit.

I played the same song at the same volume with both the stock subs and the ghosts and the bass was lower than stock. It was tight bass. Punchy. Not nearly as rolling bass as stock. Its not until you get well pass 50% that they start to shine and over take the OEM subs.

At least that was my experience.

Does anyone have solid EQ settings for a 23' iDrive8 system?

[redbullfan]

So installed the ghost subs in my x3m and they sound much tighter. There's not more bass then stock but it's just right imo. Still breaking them in hopefully they get better

I took the buyer of my 2012 Audi A4 Wagon for a drive in my G80 last weekend. The first thing he told me was that the Audi's B&O sound system is much better and he's 100% right

Agreed. I have a 2014 S4 until I get my M3 delivered, and the B&O sound I have destroys the HK in the M3.

It can be disabled with BimmerLink. Just toggle ASD to off and you're done.

There's one caveat though: You have to do this with every restart of the car.

Looks like BAV is doing a 22% off Inflation Sale until Nov 28th for those interested thought I'd share. Cheapest I've seen for new, just add to cart no code necessary.

I may do the Amp upgrade soon but none of the options have been certified for the G8x that work on the G20. It will likely work but someone needs to take the hit first before I dive in.

Dumb question -- can you control sound settings of an after market system in iDrive?

Absolutely.

I have an external Amp powering my ghosts (which I'm effectively using as midbass) and that Amp passing through a signal to a powered jl 10.

Setting gains and xover points is done on the amps, but the factory eq still remains very much effective.

Fwiw, I'm very very happy with my setup, feel no need to go further. The stock speakers can very much hang once you fix the bass / midbass

Been following this thread since inception and didn't have high hopes but as someone who loves LOUD bass, I wanted to share my opinion on the speakers:

It's very hard to notice the improvement at lower volumes, but at the same time, the volume is low so I don't know if that is surprising. I am with those who have made this complaint that I'd love to have even more at low volumes.

At around 70% the bass is VERY noticably better. I am BEYOND impressed based on others (BIGWORM's review specifically) that it would be ngligible for the money. I really like the sound now. I still wish I could throw a sub in the trunk, and will if I ever can, but this is way better than stock for those on the fence and don't want a trunk sub.

I had to buy a t50 torx bit and the back bolts were just a LITTLE hard to access with the seat all the way forward, but other than that it was really easy to install.

I have a 2023 and just added a JL 12w3 in a custom fiberglass enclosure in the left pocket of my trunk and it works great. What does ASD have to do with adding a sub to the trunk?

Your fake exhaust note will now play also through your sub if you don't disable it.
Yeah my G82 sounds like a V8... gotta turn it off one of these days.
