R4F | 1000 Watts RMS / 2500w MAX - 1Ω Stable Full Range Monoblock Car Amplifier

Looking for a Low Frequency Amplifier that checks all the boxes, your quest is over. Introducing the TORO Tech R4F, a Micro Sized Low Frequency solution for both competitors and audiophiles alike. The R4F Mono Block Amplifier features a MOSFET power supply to ensure an inexhaustible stream of voltage under all conditions and utilizes a Class D design enabling high efficiency and cool running without the use of cooling fans. With competitors and audiophiles in mind we have designed the R4F to remain stable with as little as 1 Ohm loads for maximum power output.  Inside you’ll discover a Class D PCB layout that includes built-in auto sensing turn on function for those vehicles lacking RCA output, a selective Bass Boost EQ for fine tuning plus soft delay remote turn on/off circuitry that eliminates pops and clicks. Our inclusion of differential input switching allows for twisted pair or single end RCA connections to eliminate all noise that can occur from different source units or due to
