The Power T500X1br 500 Watt mono ultra-compact amplifier is built on Rockford Fosgate’s patented Boosted Rail technology that sips current while retaining a storage reserve for extended bursts of power. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.
