4.1 પાવર કનેક્શન
Connect the included 12V DC power supply to the DC12V input on the amplifier. Plug the power supply into a standard wall outlet.
For automotive or motorcycle applications, you can hardwire the amplifier to a 12V battery system. Use the included PSU's wire and connector. Strip the wire as shown in the diagram below. The white wire is POSITIVE (+), and the bare wire is GROUND (-). It is recommended to install a 2 Amp fuse inline (not included) for protection.
