My 2015 F56 MCS doesn't option with HK sound system, I found this on ecstuning, My A-pillar doesn't come with these speakers. Will this A-pillar with HK works on my car?

 

Hello,

You would have to tap into the stock wires and then run a crossover for the tweeters as the stock system does not have those. Also there is no dedicated line for output and sound is lower than the stock H/K.
You could flip all the speakers over to H/K but there is no upgrade system with wires, as the main harness and everything would have to be replaced, in the future we may have aftermarket system to upgrade from the base system.

 

You can buy some nice component door speaker replacements with tweeters. Add an amp and a Digital Sound Processor and if you feel you want big sound a 10" sub in the back. HK isn't anything special imo. Check out parts express dot com or other online vendors. I used BavSound speakers, but after much thought I realized I overspent and would have been better off elsewhere.

 

I wanted to upgrade the stock system on my 2017 F56 Justa but didn't like the look of component tweeters stuck to the dash. So I added these and am very pleased with both the look and sound.

 

This guy is selling his stock HK speakers

Not sure where you're located bu I have complete HK speakers, under seat subs and amp for sale. Let me know if you're interested.
But another route is doing full BAVSOUND stage 1 ($300) + Ghose subs (600) + Match Up 7BMW (800) for much better sounds (but cost $$$)

 

Does the Match Up 7BMW work with the HK speakers or just the stock system?

 

It works with both setup.

 

But how does that work though? I'm not much of an audio guy so not sure how the current stock speakers connect, or if a component speaker can be used without tweeters? Are amps big? I don't want to lose precious space. Will any aftermarket fit or would I need some special bracket or something?

 

Depends on if you have the HK system or the base set-up.

 

My F55 is a non-HK set up. In my case, my left speaker is going out, so I'm doing initial search on if there's a decent aftermarket speaker I can throw on there for relatively affordable price. sorry for the bombardment of questions lol

 

First thing is to swap speakers so you know if it is the speaker vs. the wiring or the head unit.

 

I have HK setup and switched to:

Front:Focal K1
Center/Rear: Bavsound
Subwoofers: Bavsound
Amp: Match Up 7BMW

Then, installed Bavsound front speakers to my wife's 2018 330i Non HK front. + later, added JL micro sub 8" with built-in amp.

So I'm pretty familiar with sound changes with these additional setup and my recommendations are:

1. If you like to listen music loud, keep the speakers and add an amp only.
2. If you want, more complete fulfilling sound but not listening too loud, get, Bavsound. it's only 300 (for Non-HK) and you will see some sale during Black Friday time. Bang for the bucks.
3. If you're missing base, just get external bass unit like JL Microsub+ 8". (I was pretty disappointed with Ghost Subs upgrades even after adding a Match amp).
4. If you want to be super cheap and get decent sound, just upgrade front speakers - Eton or Bavsound. (When I added front Bavdound speakers on my wife's 330i, I noticed much better sound instantly without any other upgrade)

You can stage them but 3+4 setup (or 2+4 setup) will give you the most bang for the buck setup.
