    Do you mean turn on/off pop, could be tricky to solve

    Or do you mean like a hard knock sound, this could be the voice coil former on the sub bottoming out on the base plate. If this is the case then remove the sub and inspect the Spider to see if its torn or seperated from the basket.

    Sounds the same as my earlier topic, Saxo lad, but the noise is from the speakers :?

    Turn on/off pop is normally because the source is shutting down before the amp, so the amp gets a spike down the signal cable. Not all combinations of equipment do this in fact some are even intelligent in the fact they shut down the remote to the amp before shutting down the source, you're only talking milliseconds.
    To see if this is the problem you could try removing the remote wire from the amp while the rest of the system is powered up , be careful not to touch it to the amp casing tho.

    I remeber trying a trick with capicitors years ago but can't remeber how you wire them in :? Perhaps someone else will know

    I played about with the capacitor idea a while back in my ols astra, it did work, but can't for life of me remember how i did it now! I've also heard that it helps if you earth ur headunit to the same point as ur amps, i.e. run an earth wire from headunit to amp, not through normal connector block.....worth a try i think.
