I accidentally purchased a few LCI M3 speakers thinking they were Logic 7. The car had full logic 7 wiring to the center dash and rear doors and I made an incorrect assumption. The speakers I got are bronze in color rather than the normal L7 silver. They are also 4 ohm which won't match the L7 2 ohm speakers I already have. The M3 speakers will go on ebay and I will purchase the correct ones.

My question is regarding the subwoffers. They looks like L7 but the part number on the sticker is not BMW. Realoem say part number should be 65137838907 and 65137838908 . Thoughts? I am inclined to just sell it all on ebay as M3 as M3 parts sell for a little more than normal parts.

Which speakers did you buy? I may be interested in some/all of them.

Forgot to post the pictures. The ones I will probably sell are the 1 center, 4 rear deck and 2 subs. Ignore the silver speakers.

The speakers are rare individual audio speakers and the subs are stock hifi. I am putting in F series speakers in my car this week and will have my full logic 7 speakers and subs for sale.

Thanks for the offer and also pointing me in the right direction. As expected, 752 speakers and amp are different part numbers than 677 L7. The good news is 752 and 677 share the same wiring diagram. In the end, all I really wanted from that parts car was the complete L7 wiring harness as that difficult to find on ebay.

For those that are curious. The M3 sub is slightly larger than the base E90. It is 5 ohms and the base E90 is 2 ohms.

You would need a cross over & a special harness to make the front door speakers work

the subs are from individual audio system too

The good news is I did not get any of the M3 door speakers. Just center, rear deck and subs. Those are going on ebay soon. Not sure how to price them as there are not many others for sale.

The amp has some very thick wires going to it. This system looks to be high power but 4 rather than 2 ohms for all speakers including the subs. They probably dulled it a bit to make their $1900 upgrade sound better.

Sorry to burst your bubble, but the speakers you have connected to the tweeters are not rear deck speakers. At least from my experience they are not.

The part number for the rear deck speakers is 65137838915, which is the same as the center channel. Those particular speakers have a tweeter mounted in the center.

I'd check the part numbers.

Front door - 65137838905
Rear door - 65137838916
Front door tweeters - 65139217909

I pulled them from the rear deck myself. Here is what reaoem says http://www.realoem.com/bmw/enUS/show...diagId=65_1756
