This upgrade results in louder, cleaner, and more responsive audio.\n\nEngineered for superior sound quality, the KTP-445A boasts an exceptionally low noise floor and a meticulously clean signal path to eliminate interference, resulting in an 82 dB or better Signal-to-Noise Ratio at 1-Watt. It also features ultra-low distortion, with THD+N less than 0.03% at 1W and only 1% at its rated power, ensuring a crystal-clear and distortion-free listening experience across the entire audio spectrum.\n\nIts standout feature is its compact design, measuring just 7-7\/16” x 1-1\/2” x 2-1\/2”, which allows it to fit in tight spaces, often behind the dash, making installation quick and easy. The amplifier is equipped with direct plug-in connectors for select 2005 and newer Alpine head units, simplifying the installation process without requiring large power cables.","brand":"Alpine","offers":[{"title":"Default Title","offer_id":52686866284856,"sku":"KTP-445A","price":296.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660181161.jpg?v=1784877699","url":"https:\/\/store.motormia.co\/products\/45w-x-4-channel-class-d-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
