    Question Sounds cuts out randomly when Sub attached

    Setup info: Sub connected via SUB pre-out on HU and Front comp's amped vis the Front Pre-out on the HU (lots of wires going to/from the boot, lol) Rears directly wired (not amped). Both AMPS have independant live fused feeds from the battery, and are seperatly earthed also.


    If I Disconnect the Sub its fine, but when connected and with the volume at any level all sound will randomly cut out (although CD will carry on spinning/playing). It will stay silent for anywhere between 5 seconds and 60, then it could be anywhere from 1 second to 60 before it goes silent again.

    I'm guessing a fault in the SUB AMP is causing the HU to go into protect mode or somthing?

    I should add this is a recent fault and was previously working fine, but happened before my recent head on 'tap' with a post, so is not a result of this low spead, slam panel bending, bumper breaking, bonnet denting impact.

    I would check the signal / remote wire for any breaks between the HU and amps, making sure they are connected 100% as this can often send equipment into protect mode.

    If thats 100% check the earths havent came loose over time or anything, and also the wiring at the rear of the HU itself (again no breaks etc)

    If the above doesnt sort it then its equipment failure along the line.

    to me it sounds like its clipping the signal
    try turning your gain down a little, may be too high
    check earthing points too. soldering the wires is a good idea to ensure good connection.
    does this happen only when its loud or quiet aswell?
