    Question Pioneer H/U Problem

    I have a DVD/MP3 Pioneer H/U and everytime I change the source, ie: Radio to CD, or change from one preset radio station to another I get a thud from my sub. What could be the problem?

    Thanks

    Found this.....although says turn on turn off..thats effectively what your doing changing the source.

    Turn On/Off Thump
    Turn on thump can vary from a slight pop to a mind shattering, teeth rattling BOOM! This thump is caused by the audio circuitry stabilizing when power is applied. Most amplifiers and source units have muting circuitry that lasts a couple of seconds to allow these fluctuations to subside before passing a signal. However, if the amplifier un-mutes before the source unit or any other accessory, you better watch out. Here are some things to try if you have turn on thump.

    Verify that the amp has a good audio ground reference.
    Don't install the system so the amplifiers can be switched on when the source unit is turned off.
    If you still have thump, add a turn on delay module in line with the remote turn on wire to the amp.
    This concludes the section on turn on thump.
