There are two ways to connect any FAST compatible Tube, EITHER using the FAST System or by connecting to the positive battery terminal of the battery like any other installation. Again, this is an EITHER/OR situtation.
The FAST System was developed and designed to make installation a breeze. Due to the amplifier design of the FAST Compatiable Tubes, amperage draw is quite low, allowing for a safe and secure power connection at the headunit using the factory wiring harness,
