Hello All,
I did not see a post that had all of the speakers involved in the project so i thought i might start one.
Firstly, thank you to SirSchwag, Lippy et all,for all of the help with me so far.

FRONT DASH TWEETERS
So we know about the tweeters. BURM AMT's can go in with mods to the dash holes...but have a different impedance, so that needs to be considered. The Rear BURM tweets will replace the front BOSE ones, but you need to transplant the caps, shave male connector tab. Getter done

So lets move onto the other drivers:

CENTER: Can anyone confirm the impedance of the BOSE and BURM drivers? Also, has anyone gained access to this center speaker ? Does that center panel just pop off around the SC? If so, how ? Anyone have a diagram of the clips ?

FRONT DOORS (Mids) this looks like it is a straight swap, same impedance, no caps to add, remove door panel, Getter done
FRONT DOORS (Woofer) Can anyone confirm the IMP on both of the stock BOSE and BURM drivers ? Are they physically a straight drop in ?

REAR DOORS (Tweets) Straight replacement, no CAP required . Pop off panel, Getter done
REAR DOORS (Woofer) the Burm Rear woofers look and cost is different to the front woofers. Does anyone know the IPM of the BOSE driver and the BURM driver for the rear ?

SUB, undiscovered country as far as a speaker swap.

Wow. Quite an undertaking. Curious, I have the Burmester and love it, how much did all the speaker parts cost? Did you buy through Suncoast? Also, why did you not consider an aftermarket option like Focal or jBL? Also, the speakers are tuned electronically for those brand if speakers (Bose settings for Bose speakers), so how would it sound with the Bose EQ and speaker settings with another brand of speaker, much less a Bose amp driving a Burm speaker? The Burm system is a much higher wattage system and good, high end speakers need a lot of power to drive them and make them sound good.

Chose BURM mostly because the fitment is direct, factory fitment. I acquired some speakers directly from a most excellent forum member , mentioned in this thread.
Others can be had from Suncoast. I partially agree on "tuning" of the speakers for the subs, the mids maybe as well. As for the tweets, if you use the same HP filter Cap, that should be the same...but better Not sure if anyone else has changed the MIDS/SUBS.
We forge on.

I shall be watching this closely... Godspeed and good luck!

This is currently how I am running my Bose sub. The Image Dynamics ID8 fits with a spacer and the enclosure has enough volume. Sounds much better than the stock driver.

 

[Teddis]

Mangotango,
An amazing contribution, thank you !! Glad it sounds better. I am sure a better quality driver (not paper i.e. BOSE) will sound and last longer.
Do you still have the original SUB Driver ? If so, could you possibly measure its resistance, and diameter ? We can then add it to the "known" BOSE SPEAKER list.

Great work ! Where in Canada are you ?

 

[mangotangoe]

measures 1.7 ohm.
Right next door in niagara.

 

[Teddis]

Thanks , so confirmed it needs a 2 OHM replacement.
What was it like to dig out the enclosure, and the speaker ? Novice , or off to the shop

Niagara ! Cool , have you done any other audio Mods to your Mac ?

 

[vandit]

Teddis- admire your audiophile enthusiasm. These are one of my favorite threads. I love music and audio equipment.

Question I bave yet to see u address- how do you account for the probably double the amp output to the speakers you are replacing ? Can you add an extra amp? Those speakers need wattage

 

[Teddis]

Hi Vandit,
So far I have only replaced the tweeters, they measured the same DC Resistance..I am not sure if the sensitivity is similar to the Bose as we do not have data on the sensitivity of the BOSE or BURM drivers. In my limited audition of my new burm tweets, they are cleaner, I have reduced my treble setting, for me, thats a good sign. If we used Focal,etc, we would have sensitivity data.....but what good is that if we do not have the BOSE data, to know if we are a close match. again, factory fitment/OEM is why i chose BURM.

I agree this can be a problem. I am making sure however that at least the IMP matches so the AMP does not see a different load. Can any of the top electrical guys comment on the sensitivity "match" concern ? I may do one at a time and see if there is a volume/quality issue....I doubt it personally. I think the speaker is just replicating what it is sent.....and the BOSE amp has enough poooop to drive it.
thanks

The swap of driver for the sub is an easy diy. The dual coil 4 ohm driver was wired as a 2 ohm load. No modifications to the enclosure are required.

I have replaced my front tweeters with a set of MusicCarNW Dynaudio and removed the front center speaker. No plans for any change to rear speakers but will eventually change out the front door speakers. Would love to install a DSP processor to tie everything together and get a nice front stage.

 

[Teddis]

Great news on the disassembly. I will do this next as I ponder the mids and woofers in the doors.
Say, how did you gain access to the centre channel ? I think you said you removed it ? did you measure it at all man ?
thanks

 

[mangotangoe]

Here is the bose center speaker. Cant remember clip positions, but center dash panel came out fairly easily. I found a diagram somewhere.
speaker is 4 ohm

 

[Teddis]

4 OHM is great news. The Burm is as well.
We move on.

My sub is under surgery as we speak. Stand by.

 

[Teddis]

Following Mangotangoe's lead, I will be installing the Rockford Fosgate P1S28. Its local and meets the requirements. I will post up some pics and a review early next week.
I am not expecting to have a huge impact on the SUB sound. More so I know it is a quality driver, and not made of paper cones

 

[Teddis]

So my Sub speaker swap is complete. This is a very simple DIY project. From only a little listening so far it sounds great, the Bose did not sound terrible.....its just not well made....see pictures. More reviews once I get this little driver worked in a bit.

 

[USCGTS]

I now have replaced the tweeters, center channel and sub driver. I have noticed a pretty decent sound improvement. The cheapness of Bose speakers is shocking.

Now the next step is the door speakers, they are on the way. I am seriously considering the B amp. I just need to learn how the car HU learns it has B equipment, PWIS or is it a different HU altogether. Obviously not buying a new HU. Would a B amp work with Bose software and how would it sound etc is the issue.

For those in Southern California I have a friend who is an expert at this and works only on high-end cars so if you ever wanted this done give me a PM and I will shoot you his info.

We just did a great LED lighting upgrade in my Macan that illuminates my speaker grils ( like Audi/MBZ) and does a phased tun on from front to back of the Macan, pretty cool. Lots of colors etc etc. As well as a built in radar/Lidar/Jammer system with installed display in the mirror. Our next project is a HUD that we have working only need to build a custom enclosure.

So he is very good.

 

[Teddis]

Great update USCGTS.
You are breaking new ground here man with HU alternatives. That you have access to PIWIS is fantastic.
Keep us posted man !!!

 

[Teddis]

Just completed the rear Burm tweeter swap. I can confirm that there is a cap in the OEM Bose tweeter.
That needs to be transplanted to the new Burm tweeter. Fits perfectly and plays nice. No extended listening experience yet.

 

[Teddis]

So with more driving/listening time in now, here is what I can report.

The Rear tweeter upgrade has made a HUGE difference for me, here is why....and this may vary for others.

I sit with my Drivers Seat all the way to the back, long legs. so, my head its actually closer to the rear door tweeters than the dash !! These new drivers made this very apparent as they became, not louder....but more apparent and in the stage.
I also reduced Treble a bit more to my liking. super happy with this. As others have stated, this is the best bang for the buck BOSE driver DIY upgrade.
