Message: <blockquote data-quote="jarance" data-source="post: 33867" data-attributes="member: 21"><p>The woofer sound were a bit distorted for my rear and front speakers.Open it up and found the foam surround for the speaker were corroded and breaking into pieces.This was due to aging similar to the roof cloth of our rideBought a replacement 1 speaker from BA for around RM180 for testing (could be less) as shown below.<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/Selectresize_00012_zps959075e8.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/Selectresize_00012_zps959075e8.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Replaced the speaker and test it. Found that the bass was lacking after the new speaker was installed.Investigate further on the lack of bass and found that the original speaker were rated at 2 ohms instead4 ohms. :banghead: Google a bit and found that there are some website that sell the foam surround for the speaker.One place was simply speaker which sell it plus load of information on DIY.<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/2013-04-29_123528_zps291e9768.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/2013-04-29_123528_zps291e9768.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>order the part for about RM112 for 2 pieces, glue and instruction manual.This is what I got in the mail after 2 weeks of waiting..<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/Selectresize_00016_zps2fa9457b.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/Selectresize_00016_zps2fa9457b.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Did the DIY for the rear speakers. After replacing, the bass sound is so much better. Here is a picture of both the speakers after the foam surround is replaced.<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/Selectresize_00019_zpsbfd43c13.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/Selectresize_00019_zpsbfd43c13.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Note: the foam was slightly bigger and have to trim a bit. Z4 speaker is slightly different from E46 speakers.Since my front speakers is also damaged, I decided to search for a alternative and look for a generic foam replacement.Found another place uneeksupply. The foam dimension advertise meet to the existing speaker dimension.<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/Selectresize_00024_zps36fe3403.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/Selectresize_00024_zps36fe3403.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Foam Surround specification<a href="http://s122.photobucket.com/user/pbjy/media/E46%20Speaker%20DIY/2013-04-14_123741_zpsd6727571.jpg.html" target="_blank"><img src="http://i122.photobucket.com/albums/o271/pbjy/E46%20Speaker%20DIY/2013-04-14_123741_zpsd6727571.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>As the price was relative cheaper, I decide to order 2 sets in order to save on some shipping cost.The package came after 10 days. On checking, found that the outer dimension is actually 158mm instead of 156mm.I have to trim about 2 mm off the foam in order to fit it properly. Did not buy the extra glue as the glue from simply speaker is enough for the repair of 8 speakers.Note:The refoaming take practice. I have to redo one of the speaker as I did not centre the foam properly.The sound was horrible when I test it. So a cheap alternative to better sound other than replacing the original speaker is to refoam it. :rock:</p></blockquote><p></p>
