genas1de Posted September 30, 2009 Report Share Posted September 30, 2009 I saw this mod somewhere else... and they'd popped out the two circular sections behind each of the speakers. Here, have a look.... http://forums.m3cutters.co.uk/showthread.php?p=90543 I take it they do this if you have the HK upgrade factory fitted???

M3BIMMER Posted September 30, 2009 Report Share Posted September 30, 2009 I dont think ive ever heard a rattle to be fair though i will keep this mod in mind just incase, think i will do it properly without tennis balls, Link to comment Share on other sites More sharing options...
RickyZ Posted November 18, 2009 Report Share Posted November 18, 2009 The sub is only on the Harmon Kardon set up It is in the ski hatch in the middle of the rear seat back http://www.realoem.com/bmw/showparts.do?mo...hg=65&fg=20 dicky, Is this only for the convertibles or did u mean for the e36 its in the seat back. I have the harmon kardon in mine and the 'subs' are in the rear shelf. Link to comment Share on other sites More sharing options...

Wayne D Posted November 21, 2009 Report Share Posted November 21, 2009 Glad some one dug up this thread, the rattle in the bak of mine is doing my head in... I was going to book it into an Audio shop to see if there could see the problem, no need now tho.. Link to comment Share on other sites More sharing options...
scorcher Posted August 12, 2011 Report Share Posted August 12, 2011 Yay - did this today after a 3 hour drive with horrific farty bass from the sub. 75p spent on three ex Wimbledon tennis balls and it sounds soooo much better! Now really need to fix that front speaker Link to comment Share on other sites More sharing options...
eazyoner Posted May 15, 2012 Report Share Posted May 15, 2012 is this worth doing if you dont have a hk set up but an aftermarket boxed sub in the boot? Link to comment Share on other sites More sharing options...

eazyoner Posted May 22, 2012 Report Share Posted May 22, 2012 Well a combination of that and removing the hk sub plates to do the tennis ball mod Has made a huge difference..no rattle anymore so sound is much better and allows more bass into the cabin from the boot Link to comment Share on other sites More sharing options...
David M Posted May 8, 2021 Report Share Posted May 8, 2021 (edited) Thanks very much for this. I Googled this in desperation, as the shelf rumble on my 330ci was driving me up the wall. It took 20 careful minutes and problem completely solved. Thanks again!. Edited May 8, 2021 by David M Link to comment Share on other sites More sharing options...
