    What do you mean buy shake? Are you talking about vibrations caused by the woofer?

    Well if you have a fuel injected car you will have an electric fuel pump. All electric fuel pumps have a certain operating range, most cars are from 9 volts to around 16 volts, so when your bass hits your amp is drawing a lot of voltage and may be causing your electrical system to drop below its normal range which can cause your fuel pump to switch on and off very quickly, or your battery could be dropping a cell.
