Precautions
Use the subwoofer only in a dry and well-ventilated area.
To ensure effective performance, this subwoofer is recommended to be used in an ambient temperature
of at least 5 ° C.
To supply power to the subwoofer, use a 12 VDC power supply, the negative terminal of which is
connected to ground. Before connecting the subwoofer, make sure its power requirements match the
vehicle specifications.
To ensure safe movement, it is recommended to set the volume on the sound reproducing system so
that it does not interfere with all the noise of the surrounding traffic.
Warning
The technical capabilities allow the SW-T20A / T25A / T30A subwoofers to create high sound pressure
levels. It is recommended that you select an appropriate volume level for your audio system.
To ensure safety, it is extremely important to securely fasten the subwoofer enclosure in the trunk of the
car (when securing the subwoofer with screws, you will have to drill holes in the metal parts of the car;
make sure that this will not damage the fuel tank or other structures).
