OMG that guy is such an idiot.. amp racks dont make your car louder.. RUBBER AMP RACKS do!! duuh.. earth to noob audiophiliacs, RUBBER amp racks will allow the sound waves in your car to BOUNCE off the amp rack and onto your face/Termlab and hit you harder. its like you when you drop a rock off a one story bulding and the same rock off of the empire state building.. the empire state buldings rocc will catch more speed due to the distance it travels descending from the sky. like when the sound waves bounce off the RUBBER amp rack it will bounce 100 times harder and faster causing the decibels to not increase LINEARLY but EXPONENTIALLY. that is why speakers are made out of rubber. you morons!
