Replace front Base Audio speaker with Logic 7

Hello audio lovers
I have the Base audio setup with the paper cone speakers at the front door.
I am looking to upgrade if possible just the mid speaker, I already fitted Hi-Fi Tweeters.

These Base audio speakers state 4ohms on the back so no guesswork here.

But there is no spec on the Logic 7 front door speaker 65136945412.

Can they be swapped without any issues.


Appreciate any feedback

I don’t see the benefit of doing it unless you get the amp too. I had the base stereo too and retrofitted the alpine kit + hifi coding. Big improvement.

I have the base audio speaker setup but aftermarket Pioneer stereo that pushes same power as the Alpine amp.

The door speakers and sub-woofer have really woken up.

I was going down the route of Alpine retro kit but for the price plus cost of coding its not really a great improvement.
You cant even choose a different EQ like aftermarket stereo.

The Alpine amp is not not that great as its not powerful enough to power any aftermarket subs with the 40w RMS

Yes, it will work without a problem! The logic 7 speakers will take a good bit of power as well when crossed over properly. If you are running full range on a deck you will be fine.

Sorry to jump into this, But could anyone answer this question for me, I have cic Idrive with DAB radio & base audio, I spoke to bmw about the alpine retrofit kit & they said it wouldn't fit my car because I have DAB radio, I would of thought the DAB module just fitted the back of the Idrive unit.

Any help would be appreciated.

Thanks

The Alpine retrofit has nothing to do with which head unit you have .
But its not very cost effective for what you get anyway.

Yeah the DAB module sits where the Alpine retrofit would go.
So its a matter of finding some other place to fit it.
Better to go with and aftermarket amp maybe in the normal stock amp position.

Specs for the speaker as far as speaker impedance are contained in the following links.
