I can’t find any detailed information for any of the Canton systems, let alone in the Enyak. However, the spec’s for the sub I believe to be 5″ in diameter, 2 x 8 ohm double voice coil and 200Watts peak, which in real terms is somewher between 130-150 RMS Watts (continueous power). Whils’t not head banging, it should be more than noticeable, especially with 600w peak power available across the system.
I still believe there is a power issue at the amp or a connection issue… Comparing the sound to another car, let alone a different model is poor. RMS voltage is the equivulent to DC voltage and can be measured by a multimeter, to give the approximate power. for example RMS value is 10V (ms) the power disipitated by that load is 20W.
