    Hi ... I've put up with the poor audio from my 5 Series BM for over a year now & have decided to "upgrade" in some shape or form
    The main problem is lack of bass (!)
    As I see it there are 2 possible fixes ...
    1) New head unit - I was amazed what a difference a £250 Alpine head unit made in my last car (Astra) & when I then put it in my wifes car (Clio) The Clio in particular went from no bass to decent bass - the Alpine is 4x40W I believe
    2) Wiring a sub & amp into the existing setup
    I would prefer No2 as the existing head unit is an integral part of the front dash etc but dont really want to waste my money if there wasn't going to be a significant improvement - subs seem to come in all shapes sizes (& prices!) - what would I need & how much would I have to spend to see a decent improvement (What would fitting cost ?)
    TIA ... Paul ;)

    Have you considered upgrading the speakers that are already fitted?

    Upgrading the head unit is simple enough but with head units these days producing some serious wattage the original speakers may not cope too well, and if the frequency response of the original speakers doesnt reach deep enough for your tastes then supplying them with a cleaner and more powerful signal really wouldnt improve the situation very much.

    Its only my opinion but if upgrading bit-by-bit I'd go..

    1- Speakers
    2- Headunit
    3- Sub

    Kev - apparently doing anything to the speakers in my car is a real @rse!
    I have decided to do the head unit first (after advice from a selection of local ICE specialists)
    I was going to spend about £200 but have taken a fancy to the Alpine 9812 & it is over £250 :eek:
    Anyway as with all my upgrades I'm sure I'll get round to the speakers (& sub) but a decent head unit will be needed to get the best out of whatever changes I make ...
    Paul ;)

    Remember the cardinal rule 4 x 40 or 50 watt head units output nothing like it. The majority output between 12w and 15watts (if you are lucky). Most if not all headunit will play 20Hz to 20 Khz so that points to the speakers. If you are getting little of no bass, then I would bet my life that new speakers are the answer.

    A sub will help but you need decent kick up front to lock the sub to your front soundstage.

    Most door speakers at 5 and 1/4" or 6 1/2" speakers so the job should not be too hard. Getting the door car off should not be too difficult either if you can find a resource for it. :D

    Samhain - thanks for the input - as I said in my initial post a good quality HU in my last car (& now the wifes) was a vast improvement over the stock HU
    The BMW Business CD/Radio is noted for its lack of power & my new purchase professes to have 60w x 4 so even allowing for your comments above on rated output there should be plenty!
    I anticipate adding a sub - I like bass! - although I dont want the car to be heard before you see it (if you get my drift!)
    IF it transpires I need to upgrade my speakers too AFTER adding a sub then I will only do so if they can be fitted in the existing housings (of which there are THREE in the front doors / pillars
    I'll post again when the HU is up & running & you can all tell me "I told you so" :nono:
    Paul ;)
