    Hi guys and gals i got a problem with the sound in my car. its been doing it for a few days now i think its a bose system in my car where the front speakers run off the head unit and the rears and box are amped,
    it seem to be turning on and off ive looked and checked the wires behined the unit and all are fine,,,,,,

    Its like this when i turn left it goes off when i turn right it comes on when i pull away it goes off and when i stop it comes on but saying that its gone off now and has not come back on ive looked at the box connection and rear door speaker connections and all is fine is there any where else i can look
    Cheers gareth

    ps the reson for the title is it almost killed me swerving today on a gravel trail trying to get it to work almost rolled it so wont do that again lol

    On the Bose system all the speakers are separately amped, none run off the HU.
    Is the HU turning on/off or just the amp?
    It won't be anything to do with speaker connections if it's effecting all speakers, if all the connections are good then it's most likely the Bose amp giving up due to dry solder joints. If you can use a soldering iron it would be worth running new solder into the main joints on the PCB, suck out the old stuff first with a solder sucker. This works pretty much everytime with intermittant problems on Bose amps.

    Im not sure whats in there to be honest i know that when i changed the head unit from the original one to the one i have now i had to buy a block with wires from halfords to connet the rear spekers and rear sub to the unit and there is nothing on the speakers. my car is an avant if it helps and on the left hand side behind the panel there is a sub. and its just the rear speakers and sub

    Disconnect it all and run fresh cables to the rear speakers from the headunits output. My old Avant had the factory rears bypasses and I built a box from MDF which housed the 12" Kicker sub and a pair of Kenwood 6x9 speakers in their own individual enclosure in the same box running off a 4 channel amp for the 6x9's and the sub and a second amp running the front speakers. Not ideal but it was all kit I had lying about so apart from the MDF and cloth it didn't cost me a bean.
