So I've been listening with the AlphaOne amp upgrade on my Hifi system for about 2 weeks now and while it is definitely much better than on the stock amp, it still feels like Im not quite there with how I want the sound.

I'm curious what have others done in regards to the speaker & sub upgrade? Is it worth going with the Alphaone speakers & subs to match? Theyre quite pricey... Any other decent options?

Also one thing I've noticed with the Hifi is that the sound is very front-heavy in the car as all of the speakers except the 2 in the rear doors are up front. It's not that bad but definitely lacks the "surround" experience without the extra speakers in back.

For g20 m340i is there any bracket needed or does everything come in the kit itself ?

BUT as others have mentioned the fake engine noise when accelerating is louder. Its honestly not that bad to me tbh but I'll get around to coding that out soon enough. Was it worth the $? Eh its pretty overpriced amp but the base HiFi system was seriously just not cutting it and I wanted something easy to install and plug & play... Might go for their speaker & sub setup from them to complete the set to really get the system where I want it.

Did the alpha one increase ur bass or did it many make the system overall louder

SO I have a bit of an update from my previous post.
To answer your question the AlphaOne amp alone did increase the overall system volume and helped out a lot, but the bass and system as a whole was still very meh.

I went forward and got the full AlphaOne speaker & sub upgrade for the HiFi system and I can say now that it is MUCH better than the base system. I still need to play around with the amp tuning but I am so much happier now than when I had the the base Hifi system.

The only thing as I mentioned in my previous post is that because all the system is in the front of the car (with only 2 midranges in the rear doors). It is a bit front-heavy sounding. But bass from under the seat packs a punch and overall gets way way louder. Now at max volume its actually too loud. On the base Hifi you could turn the volume to max and it would be way too quiet still. Unfortunately I don't have a harmon-kardon 3 series around to compare it too but I imagine this is better except for the "surround" sound part of the HK with all the extra speakers in back. Again it was pretty pricey and I'm not sure if its really worth the cost overall, but if you have the funds then I'd definitely recommend it.

I went with a pretuned match up dsp8 from allwoodsaudio.

I plan to add some underseat 2 ohm subwoofers if that’s not enough

I purchased the same from allwoodsaudio. The pretuned setup they provide can be improved upon a lot!

Who did u use to improve it ? Or did u learn how to urself ?

I truly think the HK system in the G20 is not as good as the Fxx. HiFi came a long way and I believe the difference in sound in the two is not that huge. Of course, if you compare it to the base audio system that comes in some 320i in Europe, that is totally mediocre.

The Focal will not sound 5.5 times better than the CDT, for the price.

I came from a 2016 GTI with fender as well. It was way better than the stock hi-fi system in my 330i. I ordered a match up dsp8 amp from allgoods audio eBay store. Install was easy with the battery in the trunk and the included wire harness was plug and play.

I tuned it using the base tune supplied by the seller and tweaked from there and it sounds amazing-def better than the fender system in my GTI. I did not change the speakers, and the stock speaker sound great. They’re clear Crisp and precise. I bumped up the under seat subwoofer gain a little bit and change the crossover which definitely improved the bass output, but was still missing those Sub bass notes.

I ended up adding a 500w Rockford amp using the line out on the dsp amp and bought a 12” ported Jl sub.

My sestem is now perfect one of the best I’ve had in any car. I will not change the stock speakers.
