This bike got one of our powerful 4-speaker builds, built around the combination of our new SinisterSound 6.5" midbass speakers and Hertz Audio 6x9s. 🏍️

Up front, we installed two of our new SinisterSound 6.5" midbass speakers, paired with a set of Hertz Audio 6x9s in the rear. The entire system is powered by two Cicada Audio FLX700.4 amplifiers, giving these speakers the power they need to really bring the midbass to life. 🔊

Four speakers, two amps, and plenty of power behind them for the kind of heavy midbass we’re looking for. 🔥
