Hi

I've just fitted some decent speakers into my 2 door 6N1. They've really highlighted the loose rattly bits in the doors and I've had them apart a couple of times, tightening everything and packing bits out.  The drivers door still has an annoying buzz that seems to be coming from up near the handle. This is intermittent, which is making it hard to pinpoint.

Both doors need some sort of padding between the speaker/door pocket panel where it fixes to the main panel. Maybe a thin bead of silicone, allowed to set, might do the trick.

My question is, " Are there any known, common vibration points in the 6N doors" ?

There must be many people that have upgraded their 6N door speakers and had to deal with this.

I've had a search and not been able to find anything here on the forum. Maybe I was using the wrong search words.

Any help or pointers gratefully received.

Cheers

 

Don't have a 6N, but I glued some sound absorbing sheets on bottom half of the metal door skin of a Skoda Octavia to stop a buzz after I upgraded the speakers to big ones from TheLoudest.

 

This looks better than the foam stuff I used which was left over from a computer tower...

Thanks for that.

 

I've found a couple of sources of buzzing rattles. The speaker grill being the main one.

I've ordered some sound deadening material. some foam tape and some cloth loom tape, all to help deaden the rattles and improve the sound quality.

When this stuff arrives, I'll be dismantling the door and anything that makes a noise when you wiggle or move it will be getting padded out or fixed down.

Any sections of the door, the trim or speaker mount panel that make a highish, light sound when tapped, and bigger flat areas will be getting covered in the sound deadening material.

 

Just to add to the pool of knowledge here, I'll post my results and anything else I might learn along the way.

 

This has made me wonder how many speakers I have written off as dud when it was vibration in the housing.

After applying sound deadening material to the door cards, the speaker mounting pods, a little bit of the door pockets and every tinny sounding bit of the doors, they are a fair bit heavier and sound very good quality when you shut them now.

I stripped the door down and set about tapping and thumping to identify every bit that could cause a rattle or buzz of any sort.

I wrapped cloth tape round bits of wire, a spring on the window mechanism. Popped out plastic bits like screw hole fittings and stuck cloth tape on the door and popped them back in.

I stuck foam tape all around the door pockets where they touch the door card. I dismantled the mirror adjustment switch and re greased the springs and anything else that rattled in there. Then added some foam tape on the contact points for when it was popped back into the door handle.

I packed out bits of the window motor with high density foam and lashed it to the drivers door with a heavy duty cable tie, as it was a non OEM replacement that was missing a mounting bolt hole.

They were little bits of metal in the bottom of the door from a broken door lock. They had to come out as they were rattling.

Anything that sounded even remotely suspect with a thump or a knock was padded out, lashed down, stuck down, replaced or bulked out with sound deadening material. Which I highly recommend by the way. The sticky stuff that is silver on one side and is some sort of heavy, butyl rubber, squishy stuff, that you squash down with a roller.

This was enough to do both doors with some left over.

 

The end result is nothing short of amazing. They dont even sound like the same speakers. The improvement in sound quality at all frequencies is pretty bloody impressive. I cant believe it and I wonder how many speakers I have written off in the past when it was just lightweight, loose, buzzy bits in the door or shelf.

I was promised these speakers would be a big improvement over the standard items and when I put them in, I was disappointed.

After the sound deadening and rattle treatment, they have certainly delivered, in a very pleasing way.

I hope this helps some folk who might be looking at the same issues I had.

 

 

 

What are the speakers?
