My Ride: 2003 E46 Convertible
E46 Replacement Speakers

Hi Everyone,

I just bought my first BMW and am new to the community (and cars in general). I have a 2003 e46 convertible with HK speakers. I want to upgrade my car's speakers - I've spent hours researching and it's very confusing. Can someone help me piece it together?

I'm looking to spend $300-$400 on parts, and have an electrical mechanic who could install for me. I listen to a lot of electronic music, so bass is very important.

If possible, I'd like to include a subwoofer, but that means I'll need an amp and can get very expensive. Do people know a good mid-bass I can use instead of a sub?

Here are the product I've been considering:

Door Panel: (I think this is only the mid-range, missing tweeter)


Lower Front Door:




Rear Speakers:

no options yet, looking for suggestions

If anyone has specific product suggestions and recommendations on amp/subwoofers, please let me know!

My Ride: 02' 325xi OrientBlue
I have just replaced my 325xi sedan's speakers with a component set for the fronts, and a 2-way coaxial set for the rears. Everything is SO crisp. For a sub I went with an Infinity Basslink which puts out more than enough bass for me. I prefer a more filling bass over an overpowering abundance of bass (I don't fit the stereotype for a 15 year old, at all But I do listen to a lot of electronic music. I'll give you the links for the speakers and the sub. I was not about to pay $700 for the BavSound kit (Sorry guys) because I felt like I could do better on my own. I kept the factory mids, as they weren't too bad.The install was somewhat involved compared to putting speakers in the doors of my dad's 1996 Civic, but overall it was relatively easy. I cut up the original front door woofer to make a bracket for the new ones (some side-cutters and 5 min) and for the deck, I just set them in the hole and used three little aluminum pieces and the original screw holes to sort of "sandwich" them in there. Overall very easy after you figure out what you want to do. I am in the process of installing a 4 channel Pioneer amp so they should sound even better, but they sound absolutely fantastic with the factory amp. I guess I should mention that I have an aftermarket head unit, but everything I did will work with the factory amp and head unit.

Polk speakers rock! Get the MM6501 if you want better bass.

My Ride: 04 330cic
I have about the same car as you (2004 vert) and found that with the rear there are not a lot of options. I used:

Woofers Etc. CDT CL-4SL Audio midrange super slim speaker


Parts Express #264-1002 Vifa OX20SC00 fabric dome tweeter


The CSL speaker is thin so it fits nicely in the little space that is in the rear panel. Unfortunately it is not exactly a bolt in so I sacrificed my current HK drivers to mount the new speaker. The mids were more than I wanted to spend but they do sound nice. The tweeters fit inside the original housing but you will need some hot glue to hold them in. Also these tweeters are really efficient. I added a series capacitor that was 10 uF IIRC, which should roll off at about 4k.

The most dramatic improvement was the addition of a sub in the ski pass. There is a lot of info on this forum about building these. It seems like most use a 10" sub but I used an 8" Kicker Solo-Baric since the minimum enclosure size was significantly less than what was required by the 10". It is powered with a Precision Power i650 and delivers enough bass for my listening. It is also a class D amp and so far to date I have not had any overheating. Prior to that I used a Boss class AB amp, which also worked great until it overheated. Took about 20 minutes at elevated volume. If you are mounting the amp in the trunk go with a class D.


I have attached a few pics of what I had to do to mount the rear speakers in the HK frames.
