Make sure source grounds are as short as possible and connected to
bare chassis metal, not to factory radio ground. Beware of dash

proper connections and routing. Try another cable routed In a
different location In the vehicle. If unable to cure problem, take

right speakers. If bass Is more prominent when turned to either side,
check speaker wiring for proper positive and negative connections.
Reverse connections on one speaker If necessary.
