Stock replacement for blown 4” Base stereo speaker?

I have a blown left side 4” speaker on my base stereo (the lame 6-speaker one with no amp).

Can anyone recommend a cheap replacement? Not looking for an upgrade at all, just a working pair. I understand it will need to be a 4” speaker with the triangle shape mounts or adapters. I looked through the list but those are all upgrade speakers designed for high power amped systems.

Just need to “fix” my base system. Thanks in advance!

Look on the on the buy/sell section here or on ebay .
Better to source a stock one that will fit.

When you say base do you mean the stereo that
came with your car or stereo , Hi Fi or Logic7 .

The only year and a half the no pay for it system was
the base stereo system in the US was 2010 to 2011.5.

I have a set of two hifi speakers from my 335i (upgraded to Logic 7 mids). I can sell you one for $20 plus shipping to your location, from Atlanta GA. The hifi speakers are 2 ohms, so they should work. I should point out that the hifi speakers have bigger magnets than the non hifi mids, so you might be better off buying the set (I'll sell that for $35).

Mods, If you need me to remove the prices, I'll do so immediately.

I've read that; as I understand it, the tweeters and mids are connected in series; the hifi tweeters are 4 ohms, and since the output of the amp is stated as two ohms, this means that the mids are 4 ohms. EDIT - I'm wrong, please see below...

They are not (tweeter mid)in series they are in parallel in a Hi Fi 676 option.
I have repaced mine I know this to be true.

Base system has door speakers in parallel with the floors.
There is a component that splits the frequency between them.

The static resistance measurement on a Hi Fi door mid is 2 ohms.
And it measures as 2 ohms at the amp connector.

The above document was generated by MusicarNW regarded as one
of the best BMW stereo shops on the West Coast.

I have no seen one install that puts tweeters in series with mids
or anything else.

My mistake, then. Strangely enough, the Logic 7 mids sound much better than the hifi mids even though there is twice the resistance (unless they're also two ohms?). It must be because they're much more sensitive (I assume).

The ohm ratings are right in the documents.

Got it. I reread the docs you attached and it all makes sense now. I appreciate the help - I'm way more familiar with the E46 HK setup, as I was in a 330ci for close to 6 years, so I'm still learning the intricacies of the E9X platform. Thanks!
