RP-4500.1D | Monoblock Car Amplifier



The RP-4500.1D is the most powerful monoblock subwoofer amplifier in the distinguished and highly reputable "RP series" from Skar Audio. Designed for the audiophile seeking a competition grade amplifier with high performance results, all at a reasonable price. The RP-4500.1D was designed to handle abuse; featuring four way protection circuitry (thermal, voltage, speaker, and DC short), keeping your amplifier safe while in the lanes or playing at full tilt for hours on end. This amplifier is stable running at a daily 1-ohm operating which allows for maximum power output.


Featuring massive 1/0 AWG inputs, the RP-4500.1D can be fed optimal levels of current from the thickest of power cable. This amplifier comes with a remote subwoofer level control and bass knob allowing the user full control over their bass from the front of the vehicle. This makes for a great amplifier when looking for serious power to get your system loud, and will work great on a single subwoofer around 4,500 watts RMS or a pair of subwoofers around 2,250 watts RMS each. Class D Circuitry design. Stappable: Yes.
