No, because the Tube is not being powered by the headunit. There is absolutely no difference in performance, the FAST System allows for power (and signal connections) at the headunit instead of at the battery simplifying installation. Either way, you are using the vehicles electrical system to power the onboard amplifier of the Tube.
