{"product_id":"4-channel-power-amplifier","title":"4-Channel Power Amplifier","description":"The Alpine MRV-F340 is a versatile 4-channel power amplifier designed to elevate your car audio experience. It delivers robust power across various configurations, ensuring compatibility with a wide range of speaker setups. At 14.4V, it outputs 55W RMS per channel into 4 ohms (with 0.08% THD) or 65W RMS per channel into 2 ohms (with 0.3% THD). For even more power, it can be bridged to deliver 130W RMS x 2 channels into 4 ohms (with 0.3% THD).\n\nThis amplifier boasts a wide frequency response of 10 Hz to 50 kHz with only a –1 dB drop, capturing both deep bass and crisp highs. Its high signal-to-noise ratio of 100 dBA ensures a clean audio signal with minimal background noise. The MRV-F340 is equipped with an active dividing network, allowing for precise crossover point adjustment between 50 and 200 Hz with a 12 dB per octave slope. This feature enables fine-tuning of your system to match your speakers and listening preferences.\n\nInstallation considerations include a power requirement of 11–16V DC with a negative ground system. Due to the heat generated during operation, the amplifier should be mounted in a location with free air circulation, such as the trunk. The unit accepts input from both high-power and standard-power head units, with an input sensitivity range of 200mV to 4.0V. The speaker impedance compatibility includes 4 or 2 ohms in stereo mode and 4 ohms when bridged.","brand":"Alpine","offers":[{"title":"Default Title","offer_id":52686866809144,"sku":"MRV-F340","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660673781.jpg?v=1784877707","url":"https:\/\/store.motormia.co\/products\/4-channel-power-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
