Bimmer-Tech - Amp Upgrade - Base Stereo Only (F3x / F8x)

MSportTune2 · 01-20-2017, 05:49 AM

I am very pleased to know many more have attempted to upgrade the mediocre base system.
I did my base stereo upgrade back in Dec 2015 and was on my own then as nobody attempted to add a center channel
as far as I can tell from researching the forums.
Anyway, my sound system is a full 16 speakers Bavsound system including ghost sub powered by BimmerTech amp.
I recently got all my 4 doors soundproofed and then added a Hertz active sub DBA 200.3 as I find the bass still lacking.
With a full tune after all this, I am really pleased with my completion of a 4 year wish to upgrade my sound system.

Just sharing what you can do to take it up another notch. Cheers!

So you also added tweeters in the rear doors and midranges and tweeters in the rear deck? Which amp do you use?

I used the Bimmertech amp and then connected all the rear deck speakers to the rear door channels as recommended by Bimmertech. No choice as my initial work was getting all the HK speakers hooked up.

My system sound good to me seating infront and behind so that was my plan so my kids can also enjoy good sound seating behind.

So there are 2 speakers going to 1 amp channel?
Example: left rear door and left rear deck?

All the gongs and stuff are normal. No problems there.
I have only listened to 2-3 songs in the parking garage, so I haven't got a real experience yet.

Only thing I wonder about: I think the small harness bypasses the ASD and just picks up the signals there. I'm not sure, but I don't notice any engine sounds coming through the speakers any more. Maybe I'm imagining things

I will ask bimmertech if the harness bypasses ASD or not. They should know

I have checked with bimmertech and they said this harness will delete ASD function... i wish they could come up with a short harness while keeping the ASD working

GeertB · 02-07-2017, 02:19 PM

I haven't got a reply from bimmertech yet...
I think it should be possible, because all the signals are there... I hope to hear from them soon...

Just wondering if you ever hear their reply?

GeertB · 02-24-2017, 12:19 PM

Yes I heard from them. ASD is bypassed. They say it is not a good idea to keep the ASD with the bimmertech amp...
But you can keep it of you really want I guess.

I told them that if i really want to keep the ASD function and take the responsibility of the outcome, would they still make a harness for me, and never heard from them back....

GeertB · 02-25-2017, 07:59 AM

Sometimes they are a little slow to respond, but just keep sending emails

If they answer, they are helpful.

ASD is very loud with bimmertech amp. Sometimes will cause speakers to rattle unpleasantly too.

I added the harness to delete the ASD after adding bimmertech amp. You can also code out ASD with Esys.

Hei,

I hope you are all good. I've read all the pages of this thread multiple times. Why? Because i've decided to upgrade my audio system too.

Right now i have the base system, 6 speaker and i want to make a little upgrade. I managed to get the HiFi amp & speakers for a very small price so i decided to go for it.

Today i've spoke with someone who can help me installing the amp harness (the rest of the job i can do it myself) and he told me that it's 99% sure that if i cut the dashboard i will not find the space and system to mount the speaker.

From what i've seen in your picture everything it's there, only that the dash it's not cut ...

I don't know if he said that because he don't want to do complicated things (already said i will cut it myself) or he is right ... i wanted to ask a second opinion.

My car is an F31 from 10/2013. What do you think? Thanks

Lancelot · 05-06-2017, 01:42 AM

You want the center speaker right?
All I can say is I cut the dashboard and everything was there.
I don't think they would bother making multiple molds for the dashboard insides just because of Hifi/No Hifi.

Yeah. I think the same. i even looked on multiple ebay listings of dashboards with the central speaker and not and all looked the same on the back.

I will cut it and worst case if i don't have the speaker hold i will put the grill and that's it.

Any advice on cutting the dashboard? I ordered some sharp and small knifes from ebay like GeertB used.

Thank you Lancelot.

Thank you Lancelot.

To be honest it isn't a walk in the park, the space is cramped there making operations 10x more difficult than if the windshield wasn't there. Take your time and be patient. You've got about 10mm of foam followed by 2mm of hard ABS plastic.

I wonder if a small rotating saw could make the job easier.

Yup, already armed with patient for this job.

I was looking for a dremel like that too but don't know if it helps so much since the cut it's not perfect straight. And the "blade" it's larger than the cut for the 4 legs of the grill.

Tavicu · 05-12-2017, 07:03 AM

GeertB or Lancelot do you still have the tenplate for the cut? It will save me some time

GeertB · 05-15-2017, 12:07 PM

I don't know how to attach a file on a message here on the forum...
But can you PM me your email address? Then I can send it by email.

Tavicu · 05-20-2017, 08:51 AM

Hi,

Thank you! In the meantime i managed to speak with Lancelot and get it

I've attached it in case anyone is looking for it.

I hope you don't mind. If you do tell me and i'll remove it

GeertB · 05-23-2017, 02:23 AM

no problem

Tavicu · 06-19-2017, 08:02 AM

Hei guys. Another success story

Today i managed to make some holes in my car

)

I've bought a lot of shits to make the hole, a dramel, a thing that you can use drills at 90 deg and some small drills. The truth is you only need a modelism knife (http://www.ebay.com/itm/122409198211) and patient.

It took me ~ 4 hours because i had a problem.

I bought a LCI speaker grill because it has better grip and my car is Non LCI. The thing is on the top left hole you have a pice of plastic which will make you sweat

but with patience, a drill and a screwdriver you will be able to dig into it

You will see in one picture that the corner didn't want to fit until i cut the plastic.

I've attached a photo with the composition of the dashboard (last picture). As you can see there are 3 layers. The "leather", a foam and a pice of plastic/hard cardboard.

At the beginning i've cut only the leader and foam. Left the "nice" part at the end :P. Again, all you need to cut it is that sharp knife.

Again, thank you very much guys for the support and the template.
