The KPX300.4 is Kicker's answer. It's a weather-resistant four-channel amplifier only 3-5\/16\" wide and 8-1\/2\" long, so it fits under motorcycle fairings and in tight side-by-side dash cavities.\u003c\/p\u003e\u003cp\u003eIt delivers 75 watts x 4 at 2 ohms or 45 watts x 4 at 4 ohms, and it bridges to 150 watts x 2. That's enough to run fairing and saddlebag or Tour-Pak speakers together without taxing your charging system. Selectable high-pass crossovers (60\/80\/100\/120 Hz) and independent gains protect small speakers and help keep vocals clear through a helmet. A wide input range lets it connect to factory or aftermarket radios.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBest for:\u003c\/b\u003e Harley touring bikes, Can-Am and Polaris side-by-sides, golf carts and any space-compromised install.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePairs with:\u003c\/b\u003e Kicker Harley speaker kits, PSM handlebar speakers and KMXL powersports speakers.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: 75W x 4 @ 2Ω; 45W x 4 @ 4Ω; 150W x 2 bridged\u003c\/li\u003e\n\u003cli\u003eDynamic power: 350W\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz–20 kHz\u003c\/li\u003e\n\u003cli\u003eCrossover: 60\/80\/100\/120 Hz high-pass, 12dB\/oct\u003c\/li\u003e\n\u003cli\u003eDimensions: 3-5\/16\" W x 1-11\/16\" H x 8-1\/2\" L\u003c\/li\u003e\n\u003cli\u003eWeather-resistant; 2-year Kicker warranty (per listing)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eWill the KPX300.4 fit under my Harley fairing?\u003c\/h3\u003e\u003cp\u003eIt is built for fairing installs at 3-5\/16\" x 1-11\/16\" x 8-1\/2\".
