I've had a look at their website now..... it is missing an external amplifier as far as I can see. This means you are still driving everything off the headunit which is only 15W RMS plus ordinary quality and not enough power to drive the subwoofers.

Plus now with 4 ohm speakers instead of 2 ohm, it's only half as loud.
