B&O center (dash) speaker replacement guide request

[NGOT8R]

I forgot to answer your question about running a speaker with a larger magnet OP. Yes, there’s plenty of room to do so.

I think 4 from 8 would just make it louder.

Oh man; I don't think any of us want a louder center speaker. Ha ha. We better find an 8 ohm one then, for the system to remain stock; just with better sound. And yes, if I find something, I'd post a link. And please do the same, since I'm not very good at searching. Ha ha.

Excellent news; thank you very much for all your great help . Now time to search. Ha ha. I'd only have to source the blade terminals, especially the little one, which is not common. With RadioShack now gone (at least here), I'll probably have to order them online, and pay a ton of shipping. Oh well.

Ok, I went ahead and sacrificed my B&O center speaker for the good of mankind. Here’s another option. Get yourself some red 18-22 gauge male and female bullet connectors (two of each to make up both speaker leads). Crimp the male bullet connectors onto the ends of the B&O speaker plug and crimp the female bullet connectors onto the ends of two short pieces of wire (can buy a foot of black 18 or 22 gauge wire at your local hardware store). Solder the black extension wire to the new speaker terminals and you won’t have to try and locate those hard to find mini spade connectors. See mock up pics below for visual reference. Note: I am using blue bullet connectors and white wire for the example, but you will need red ones for the job.

Thanks a lot for your help, brother. But you actually gave me a better idea: Just solder the black wires to the new speaker, and problem solved, no? That way the new speaker can be disconnected from the connector the same way as the stock one. Having said that, I'd have to get some flux, since I don't have any. And the solder I have, supposedly with it, it's absolute crap.

But my project is quickly souring :(. Just hung up with Crutchfield, and they don't carry anything 8 ohm in 3-1/2". Actually the guy told me I was wrong, that the B&O center speaker is 2 ohm 25W, and I told him my brother NGOT8R has an identical car to mine (2019 Bullitt), both with B&O standard from the factory, and I believed him more than Crutchfield. Ha ha. Need to try google one last time, but nothing came up. And yes, if we go 4 ohms, it'd make the speaker louder, and no way any of us want that . Will keep you guys posted.

Yep, you could certainly solder them to the new speaker. Thats the best way to do it anyways IMO. For those that don’t have soldering equipment though, the spade connectors (and/or bullet connectors, should need to extend the wiring), would be the best bet.

Yeah, Crutchfield gets it wrong sometimes. When I ordered my PAC Audio AmpPro from them, they told me that it didn’t fit my Bullitt. They were wrong, it sure does fit. A member on here just asked me about the AmpPro a few weeks ago and I directed him to Crutchfield. Shortly thereafter, the member told me that he checked and Crutchfield told him it wouldn’t fit his B&O Mustang. I reassured him that it would fit and told him that Crutchfield just wasn’t aware.

While I don’t physically have one of these speakers in hand to measure, I did remove the factory speakers in my previously owned 2019 Chrysler 300 to replace them with aftermarket tweeters and they were 3 1/2 inch speakers. The mounting ring and speaker looked identical to the Bullitt center channel speaker. If I were looking to upgrade my speaker, I would feel comfortable ordering any of these 3 1/2 inch speakers from this page that show to fit a 2019 Chrysler 300. I actually believe they will fit with no modifications needed.

Look here:

3.5 speakers

I want to know about putting a resistor in line and what would that do to the circuit, maybe something like this:

https://www.mouser.com/ProductDetail/Vishay-Dale/RH0254R000FE02?qs=41svs21nsHDQOrMME1keRA==

Add a 4 ohm resistor to a 4 ohm speaker in series to make 8 ohms?

 

[Mike Pfeifer]

I came across this, so might be a possibility.

That was one of the 4 Crutchfield lists for B&Os, but they're wrong. Those are 3 ohms, so even worse than 4. Ha ha.

Look here: 3.5 speakers

Okay, added 8 ohms, and excluded paper cones, and there are 11 left. However, some are 'drivers', 'full-range drivers', and 'full-range speakers'. What the hell do we need? Ha ha. Here's the link with those 11: https://www.parts-express.com/conem...ldiameter/3~1-SLASH-2?order=pricelevel12:desc

Finally, adding a resistor should work, but you could mess up the speaker, and I haven't done any soldering since I was en engineer at Rockwell International making Hellfire missile sensors, and B1 bomber navigation boards back in the 80s. Ha ha.

The center speaker is 8 ohm?

 

[FreePenguin]

The center speaker is 8 ohm?

I think it’s 4ohm
I can’t remember. I know tweeters are 8

 

[Elp_jc]

The center speaker is 8 ohm?

Yep! 8 ohm/12.5W. NGOT8R posted a picture of the label on the first page.

 

[Matthewstorm]

This was the only 8 ohm 3 1/2 Crutchfield lists.

What about this one?
