2 ohm woofers?
 

A friend gave me speakers as a birthday gift. The right rear woofer is toast. I think. No sound from the tweeter too. I pulled out the speaker. How does it come out? The entire assembly can't be one piece.

2 ohms? Yea, the replacement two way speakers will not work. Especially being 4 ohm. Could the radio have bad outputs to the entire door? I feel like trying a used woofer before deciding to upgrade or begin replacing the radio too. :dunno:

That's weird yours are 2 ohm when I did mine they where 4 ohm , all I did was cut out all the original speaker to be left with the outer shell then fitted these speakers to the shell soldering the connectors to the original pins to retain the factory plug.

Interesting. Mine are 8 ohms.

There is no problem with going higher in ohms, the volume might be different but you just adjust the fader. Do you have the DSP or Business system ?? If the tweeters are in the door as well then it's entirely possible that the crossover is right at the tweeter so the same wiring would feed both.

Mine has a business system. No DSP. I'll have to plug it into another door to check its operation. I do need to reinstall a fixed OEM LF regulator. The Chinese one has worked well but it's too slow. I can check that speaker's resistance on that door woofer. I too thought they were 4 ohm. It's why I accepted the speakers. I did try the 4 ohm speaker. At full fade rear and right, it barely cracks a sound. It's why I suspect bad wiring or radio output. The entire panel was not taken off. I couldn't figure out how to get the shade screen off. It seems to be under the small window pillar.

Thanks dazzasgotav8. I can cut the cone leaving the metal ring attached. The ring gives a mounting point.

What is the actually speaker size? The new ones are 5-1/4" 2-way speakers. The brackets provided do fit OEM mounting holes. However, the panel does not fit properly. Fitting a new speaker into the OEM mount is better.

2 Ω power resistor in series will ohm match 2 Ω to 4 Ω. Find the crossover if there's a tweeter in the same door almost always the source of random loss of sound one driver. Especially if there tweeter still outputs but no woofer.

I`m guessing speaker original size must be around 6 inch as the ones I fitted are 6 1/2 inch , if you have a BM54 factory amplifier I know they suffer from losing channels its fitted down next to the battery in the boot.

Did none DSP and non big woofer X5s have an amps installed? I'll have to pull the cargo cover and take a look. I don't remember seeing one. I'll be installing the OEM towing harness and module soon. I'll check.

I think the amp/radio box(s) is in the trunk and the MID in the dash that looks like the radio is actually only a display.
There is probably some really good info and wiring diagrams in the TIS or Bentley manuals.

Amp for the Business/non-dsp sound system is in the left cubby, in the trunk. Note that if you need to start chasing wires from the amp to the speakers (at least on mine) they change colors somewhere in route to the doors.
