{"product_id":"monoblock-class-d-amplifier-3","title":"Monoblock Class D Amplifier","description":"The Rockford Fosgate R750-1D is a monoblock Class D amplifier engineered to provide robust bass performance for your car audio system. This amplifier is specifically optimized for subwoofers, featuring an infrasonic filter to protect your system from ultra-low, inaudible bass notes. It delivers 250 watts RMS x 1 at 4 ohms, 500 watts RMS x 1 at 2 ohms, and a substantial 750 watts RMS x 1 at 1 ohm.\n\nIt includes a variable low-pass filter (50Hz - 500Hz at 12dB\/octave) and a variable Punch bass boost (0-18dB at 45Hz) for precise tuning. It also features RCA pass-thru outputs and accepts 4-gauge power and ground leads. The MOSFET power supply and cast aluminum heatsink contribute to its cool-running operation and durability.\n\nFor added control, the R750-1D includes an onboard Punch EQ and is compatible with an optional wired remote knob (Punch Level Control) for fingertip adjustment of bass impact. Its frequency response is optimized for subwoofers, ranging from 20Hz to 250Hz.\n\nInstallation requires 4-gauge power and ground wiring, which is recommended but not included. This model also does not have onboard fuses; an additional 60-amp in-line fuse is recommended when installing multiple amplifiers. The unit measures 9-1\/8\"W x 2\"H x 7-3\/8\"D.","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52872746336568,"sku":"R750-1D","price":299.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/monoblock-class-d-amplifier-3","provider":"MOTORMIA","version":"1.0","type":"link"}
