E51 No sound from rear speakers

#1
Hi, recently purchased an '05 rider and been playing music via my phone and rear aux ports however im only getting sound through front speaker by passenger glove box! This is the same if I use the in built radio. So is this likely to be a setting I can adjust/button I need to press or something more serious 🤔It's a non Bose system which I intend to replace with a pumpkin head unit I have laying around soonish anyway so if I need to pull things apart to look closer, now's the time!

Cheers,

Sam

I imagine if there is no sound coming from the rear at all that the speakers are dead.

I know this is a problem with the E50's, and I'm sure the 51 have the same speaker cones made out of paper.

Ok, thanks Karl. I'll look into some replacements after checking out the current ones. I'll have a look on here re sizing, removal and install but pretty sure I've read somewhere it's a pain in the arse job!

Yeah, it's easier to check the wiring behind the head unit before you go poking at the speakers. It could be that a previous owner has butchered the wiring (not uncommon). But most likely it's the speakers that are dead.

With yours being an E51, rear speakers are 5.25" front speakers are 6.5".

Do you have the separate woofer in the door card and tweeter in the A pillar (front) and near the reading lights (in the rear)?

Thanks for the sizes. Not sure tbh as not with the vehicle at the moment so will check in a bit. Take it the tweeters would be fairly easy to spot though and is there a particular door the woofer is more likely to be situated in if there is one? Do you think this could be another reason for the problems then?

No, just wondered. The separate woofer/tweeter set up seems to be more robust than just having a coaxial speaker in the door card.

The door card speaker will be in the same location regardless of whether or not you have the tweeters. The tweeters will be obvious as you'll see them on the A Pillar that runs up along the side of the windscreen. If you don't have front ones, you won't have back.

I was just curious because if you have the tweeters, then it would suggest there was a wiring fault, more than a speaker fault. If you do have them, it would be unlikely for both the tweeter and the woofer to fail together.

Ok. So after another check (although in the dark) I seem to have tweeters in front pillar's but not back. There is(minimal) sound coming from rear speakers and also the passenger side tweeter but you literally have to have to have your ear right up next to them to hear them, regardless of fading/balance/volume settings.

So effectively, i currently have a fully working passenger door speaker, totally dead driver's door speaker and driver side tweeter and library issue rear speakers and passenger tweeter.

Hopefully when I pull it all apart some dodgy wiring/loose connection surface
