Retrofit Harmon Kardon speakers upgrade

I’ve managed to get hold of a used Harmon Kardon speaker system without the wiring loom.

The kit comprises of :
2 subs
6 mids
6 tweeters (incl. 2 door mounts)
1 front centre dashboard with clip on
1 amp

I’ve done a bit of digging around for the wiring loom For the g30 base system(without the tweeters) on my 530e and was advised that hypothetically the wiring loom used on the f10 and f30 should work on the 530e. So I ordered one and will be retro fitting it.

I am also looking into coding so will need guidance from you experienced members before I have someone install the kit.

09.02.19 I have received the H&K speaker and amp set and I have ordered the wiring loom for the f10/f30 which includes the MOST cable, awaiting delivery in around 1-2weeks

Wow, that's going to be an interesting project, I assume you will need to get to the back of the head unit to get a feed out to the Harmon amplifier, then run new wiring? Or is there already a wiring feed from the head unit to the rear load area where the amp will be fitted?

Either way good luck, should be a nice upgrade.

I also have the base system and I have just purchased some Eton B 100 W components speakers to fit in the front to help improve things a bit. Just need to pick up the tweeter covers from BMW then I have all I need to do it, except the time!!

Funny that your trying to put in a HK speaker system while everyone is trying to take them out for something else. What is your current system? Does it have a amp in the trunk?

That will be a massive upgrade. I had the base system as well, but fitted HK speakers instead (Two tweeters in the rear, two in the front and the four midranges). Now the sound is crisp and clear, very much unlike the base-crap system.

Hi GaSelle,

As it happens, I collected my tweeter covers from BMW this morning and as the weather was nice and I had a cancelled appointment, I decided to change the speakers this afternoon. Expected to only get one door done today but it was far easier than expected and had both installed successfully within 2 hours!

You are right, there is a marked improvement in clarity and air with the Etons in the front, I am very pleased with the results.

I hadn't considered changing the rear shelf speakers as I didn't think there would be much audible difference from the drivers seat. Did you try the front upgrade first then try the rears separately to see if they were worth doing, or did you just change everything in one go?

I swapped them all in one go; the ones in the parcel shelf are quite easy too. The only "hard" part is to get the grills removed without doing any damage to them.

Ok thanks. I may well swap the rears too at some point; I popped a rear cover off earlier today to have a look and it looks really easy - that hardest part, as you say, is gently prising the cover off to do it!

I have the base system on my G30 as well. I'm really disappointed in the audio quality... I was surprised that a premium brand as BMW can deliver a car with such a poor audio system.

I'm happy to read that you have the same audio system...

However, I'm planning to upgrade my car with the Eton B100W front speakers and the Eton B100XCN center speaker, but do I have to install an amplifier? Or can I just replace the speakers with Etons? Of course I have to buy the tweeter cover somewhere but I want to be sure that they will work on my base audio system without installing an amplifier. Do I need something some special wires or all they all included in the Eton package?

Thank you!

Hi, and sorry for the delay in reply, I don't get on here very often!

Yes, you can upgrade the fronts with the Eton component speakers at the front (B100W) and you have the option of two different types for the rear I believe... a search on the Eton website will tell you which ones you can choose.

You can simply replace the speakers without having to add an amplifier.

As for the front centre speaker... if you have the base system (ie. no tweeter covers near the internal area around the door mirrors), then you do not have a separate amplifer and you do not have a centre speaker. There are simply two front door speakers, two small subs under each front seat and two rear shelf or ceiling speakers (G30/G31).

I have only replaced the fronts with the B100W's and that is a nice worthwhile upgrade. To get any better than simply replacing the front door and rear shelf speakers will get complicated and expensive, as you will have to fit a dedicated amplifier. The amplifier you currently have is not a separate unit; it is integral to the head unit in the dash board.

For the money, the B100w is a good upgrade, but you will need to get some tweeter grill covers from you BMW dealer so you can fit the tweeters. Have a look at the Bavsound G30 installation video; it tells you everything you need to know.

Good luck.

Thank you for replying! Have you installed the B100XHP passive crossover as well? I've contacted Eton with the same question, if it's feasible to connect the front door speakers without installing an amp, and they replied that I have to install the B100XHP as well. This filter should filter the bass signal out of the audio signal. I'm not really convinced that it's required.

I went away for 4.5 months traveling and just got back. I'm itching to get this system in and the idea is to keep it as oem as possible with minor tweaks of course for optimal results.

I've contacted my vehicle sound engineer and he is going away for a few weeks and once he gets back then I should be able to book him in.

I also bought the wiring loom needed to connect the system which will run from the head unit (dashboard) all the back to the new H&K Amp as the base system has no dedicated Amp hence the need for the hiring loom to connect all the speakers and the new Amp.

This will require some work and I suspect a day and a half minimum.

I'm also considering getting sound insulation shields on the doors and under the car seat woofers.

I'll be sure to post pics when the project starts.

Great thread about speakers. There should have been a sub-woofer in the rear shelf behind the back seats. I'd love to add a HK sub-woofer there. Would you have to update the car software for this?

You are comparing apples and oranges. The OP is in the UK and I believe their base system is a lot less than that in the US. So an upgrade to an HK system is a major upgrade.

Exactly. As mentioned further above, what you refer to as "base" must be what we call "Hifi". EU Base is two full tone speakers in the front doors, two in the back and two underseat subs. No external amp.

Hifi, which is optional, adds tweeters, external amplifier etc.

Where did you source the wiring loom needed for the "full" HK upgrade?

I've got a friend who works in Auto Audio installations and he ordered it for me. As it happens I bought two in the event I accidentally make an error. Providing the first one goes alright, I'll sell off the 2nd set. I've just not had the opportunity but as soon as I do I will update this thread.

I have been meaning to start this install and after installing the WiFi antenna/ WLAN aerial a few days ago.

I was feeling confident after that install so I embarked on starting the upgrade my BMW Basic audio system (6 speakers) to the Harman Kardon audio system (15 speaker + AMP) that I bought second hand earlier this year starting with the driver side front door and began to pull the door apart.

I found the clips holding the door weren't as strong as I hoped and some broke off whilst pulling the door off.

The tweeter cable is was not only too short but there was no connection on the wiring loom for inserting the tweeter cable, unlike some of the videos on g30 audio upgrades, I suspect it has something to do with the basic UK / European models vs the Asian and North American models which have start with the Hifi system (door tweeters).

I ended up having to modify the tweeter cable and cut into the stainless steel cables and attach some old BMW wiring (copper alloy) on both ends by soldering it on covered by heat shrink tube. (I'll see if I can take some pictures)

The original cable connector would then clip onto the mid speakers on the door.

The other issue I had was though the seller on fleabay advertised as a g30 compatible kit, the tweeter covers are not even though they look very similar.

I did manage to swap the old Mids with the HK mids which were held with 3 torque screws.

I'll update this thread as I progress.

Well I've hit another snag.

The rear doors, not realising, don't have the speaker cut outs (H&K and B&W setup have mids and tweeters embedded into the door cards) so I'll have to either find a leather specialist who will cut into the door cards or I may have to source door cards with speaker cut outs.

I'm also inclined to think that the rear doors won't have the wiring loom either.

I will attempt to swap the parcel shelf speakers, easy enough you think but just getting one of the headrest off to get clear access to the speaker covers was hard enough, using the plastic pry tools I tried the covers but left it for another occasion with daylight.
