{"product_id":"mono-subwoofer-amplifier-3","title":"Mono Subwoofer Amplifier","description":"The Rockford Fosgate PBR300X1 is a powerful 300-watt mono car audio amplifier engineered for compact subwoofer systems. Its efficient design makes it ideal for vehicles where space is limited, such as trucks, sub-compact cars, electric vehicles, and hybrids, as it minimizes power draw from the electrical system.\n\nThis amplifier utilizes the Boosted Rail Technology (BRT) which is an ultra-efficient design that does not require a switching power supply to generate its impressive power output. It also features a variable hi-level DC offset turn-on circuit, allowing for easy integration into any OEM sound system. The PBR300X1 includes an adjustable 12dB\/octave Butterworth crossover, a selectable low-pass filter, and a variable 4-6 volt hi-level DC offset voltage input turn-on control for fine-tuning audio preferences.\n\nKey specifications include a power output of 75 watts RMS x 1 at 4-Ohms, 150 watts RMS x 1 at 2-Ohms, and 300 watts RMS x 1 at 1-Ohm. It boasts a frequency response of 20Hz - 250Hz +\/-3dB and a signal-to-noise ratio of 85 dB. The amplifier's compact dimensions (1.53\" x 4.25\" x 6.75\") allow it to fit into tight spaces. It requires a 10 AWG power wire gauge and a 16 AWG speaker wire gauge, with a recommended 30A fuse.\n\nInstallation considerations include ensuring adequate airflow around the chassis, especially in confined spaces, as high output levels can generate heat. Users should also check subwoofer impedance and wiring configuration, as the amplifier produces considerably less power at 4 ohms compared to 1 or 2 ohms.","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52872732574008,"sku":"PBR300X1","price":279.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/mono-subwoofer-amplifier-3","provider":"MOTORMIA","version":"1.0","type":"link"}
