I Think My M Sport Sound Quality is poor!
Guys
I used to have a Vectra C SRI CDTI on a 54 plate and the sound system in that car was really good. Now compared to my new baby 320D M Sport i dont think its really that good! I noticed this on my way home tonight with my favorite U2 song on 'One' What a song!!! Without changing head set what can i do to make it sound better??? Or can i get a custom fit head unit and new speakers?? Any advice would help? Regards Mark |

Well there's loads of options, the two most popular being the Alpine and Blaupunkt kits (look on the UK general technical forum, you'll see long posts about both). A fundamental problem is the lack of any tweeter in the system - solve by fitting either a separate tweeter (several posts on this - they fit in the "sail panel" on the front doors. The other option if you don't want to alter the trim is a decent 4" co-axial speaker. Another problem is the poor factory amplification that also doesn't have decent cross-over filtering.
The cheapest upgrade IMHO is to sound deaden the enclosures for the factory under-seat subwoofers keeping; tightens up the bass, makes it more musical, all for about £10 of dynamat/damplifier/skins sound deadening. I've done it to one side only so far - doesn't transform everything, but is a definite improvement. Combine it with some form of tweeters and decent amplification, it'll add up to nice sound! I'm personally trying a personal approach (different to most) with our recently aquired 320d SE Touring - Hertz DCX100 co-axials in the doors, plenty of sound deadening, and a 4 channel diamond amp to drive the subs and front door speakers properly with decent cross-over filtering. Give me a couple of weeks, I'll report the full set of results, but the couple of small bits I've done so far are very promising. I wouldn't bother with changing the head unit personally, too many things link in through it (steering wheel controls, trip computer, reversing sensors etc) - and most people are happy with the results given suitable amp and speakers. |

I've added a sub and amp in the boot. Definitely enhances the low range of the sound. But I agree that splits are required in the front for better high end sound.
