AUDIO>> Need help on starting my upgrade with MB Quart speakers - BMW 3-Series (E90 E92) Forum

Camembert · 09-16-2010, 03:13 PM

Hello world

Here are the facts :

- I have the most basic OEM audio setup in my E90 confort : Business Radio, 2 front door 4" speakers, 2 underseat 8" subs, and 2 rear deck 4" speakers.

I find the sound very bad, huge lack of hig medium, low medium, poor bass, etc. This is my plan, changing items slowly but surely because I don't have the necessary budget to buy all in one shot :

1 - Change front door speakers
2 - Add a 4ch PnP amp to drive 2 front door + 2 subs
3 - Change 2 rear and / 2 subs

I'm not looking for an ultimate sound system, no big power, just a clear sound.

Somebody proposed me this : Mb Quart QWD 100 coming from a very high level set : MB Quart QSD210. No crossover filter, no tweeters, just the two 4" speakers.

Item is --> QWD 100 Midrange 4" (100mm - 4 ohm) Q Series Midrange Driver

The thing is that for the same budget I only can afford a very low end Alpine Kit (note that I was planing to adapt these 5" speaker on the door panel).

So here are my question :

- Is it possible to basically replace the OEM front door speaker with these Quart ? I don't know if impedance will match
- Is it a good idea? I know that tweeters will be missing but I prefer chosing later good tweeters and crossover filters than buying bad tweeters (I prefer to stay without tweeters rather than having bad ones).

At now I haven't bought anything, but I have to reply to the quart seller.

Thanks by advance.

Don't buy anything till you understand all your options.
There a lot of threads on people trying to modify the base 2010 system here
and all the other systems to don't buy anything till you understand the system.

OUps, I forgot to mention that it's a 2006 E90

Thank you for your help. I've already read all the threads before writing this. I have the base audio, being the 4x15w setup.
I need somebody to confirm that 4 ohm MB Quart would replace the stock 4" speakers. I think it would work.
