- 1). Check the subwoofer's housing and the immediate area surrounding the unit. Is the subwoofer dusty, or do you have clothes or other items draped over the unit? These can act as insulators, trapping heat within the subwoofer.
- 2). Double-check the wiring of the subwoofer if the unit was installed. If, for instance, an installation cable was improperly placed or grounded, this could cause excessive heat to build up within the unit.
- 3). Check the compatibility of your subwoofer and the other components. Sound speaker components are typically rated in Ohms---if the Ohm rating of your subwoofer is different from the rest of the components within the sound system, it can cause technical problems.
- 4). Consider how frequently you use the subwoofer. Like a computer or car, a subwoofer will always generate some heat while it's on. If you leave the subwoofer on for extended periods of time, excessive heat can be generated.
