    Hi all thought i would try this forum aswell, my two front speakers are disorting at low volume sometimes sound ok othertimes terrible, they sound really bad when someone is speaking on the radio,

    Sometime when i have the stereo up loudish it seems fine, its really annoying do you think my speakers have had it, i did read a thread about checking the amp or something but can not find it now:uhm:, would i be best to take it to a specialist or are the speakers easy to source new if it is them what are broke, thanks Oski

    Ps i forgot to add it seems worse when cold, im sure it does thanks

    If it's the Bose system then likely cause is dry solder joints on the amp PCB, epecially if it gets better when warmed up. Resoldering the main joints on the amp usually does the trick.
    Very unlikely that it's the speakers, but could be a dirty connection to the speakers.

    Yes, the little black box with fins is the amp.

    Cheers,

    You have to partially release the boot trim to get the bottom bolt out. It doesn't just pull out.

    Ok as your looking in the boot ive taken the two cargo net holders off on the right and the front left one nearest too me, then i have un done like 4 star bolts and then have taken the trim off, ive also put my rear seats forward and taken boot matt out for more room,

    But the plastic around the amp is still not moving ive pulled it quite hard but fear braking it, is there any method too this or have i missed any hidden bolts?:confused: thanks Oski

    You need to release the 2 cargo anchors on the boot lip. Remove the 4 T25 screws on the boot lip trim and remove the trim. Remove the small plastic screw up inside the cubbyhole (behind the rear light cluster) Then the only thing holding the drivers side trim is a single metal spring clip just below the curve of the bootlip where it curves round the rear light (and the one remaining cargo anchor, but you can leave this in place). Aggressively pull the boot trim towards the passenger side to release the clip. The clip will remain in the bodywork, so pull it out and refit to the trim.
    The boot trim can then be prised away enough to give you access to remove the amp.

    Basically all the joints that aren't surface mount. Get a solder sucker from maplins which helps get rid of the old solder.

    Right i have done it it has definately made an improvement,

    i still have it to a degree, i wondered if it has made a difference as i took the amp out of my warm house into a stone cold car so the amp was warm allready if yo know what i mean as it clears up when the car warms up,

    i know a dry joint is prob hard to see but i noticed i had a few joints what looked very pitted, i will have a another go tomorrow to check i have not missed any etc, and i may take the door cards to check as speaker cineections as i have not yet done that, but i will try tommorrow morning and see if it was as bad seemed alot better still, thanks Andy a big big help,:beerchug:

    I've had the same problem (although it is only my front left speaker). I've taken the amp out and resoldered as per the diagram.

    It's exactly the same. Now what?
