{"product_id":"4-channel-amplifier-2","title":"4-Channel Amplifier","description":"The Rockford Fosgate T400X4ad is an ultra-compact, 400-Watt 4-channel amplifier built on proprietary Class-AD technology with Constant Power to deliver consistent output across various impedance loads (100W x 4 @ 4-Ohm or 2-Ohm, or 200W x 2 bridged @ 4-Ohm). This high-efficiency design makes it ideal for vehicles where space is limited, such as hybrids, electric cars, trucks, motorcycles, and side-by-side UTVs.\n\nThis amplifier features flexible integration with both low-level and high-level inputs that include an auto turn-on function. The top-mounted controls provide easy access to the built-in 12dB\/octave Butterworth crossover (switchable high-pass or low-pass from 50Hz to 250Hz), a Punch EQ boost circuit (+18dB @ 45Hz for bass or +14dB @ 12.5kHz for treble), and C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) input\/output clip detection with indicator LEDs for simplified setup. It also includes differential inputs to eliminate noise picked up by signal cables.\n\nFor reliable operation and longevity, the T400X4ad employs a 3-stage thermal lock extrusion with dual fan forced induction for cooling, alongside real-time thermal and protection circuitry. It requires 8 AWG power wire and 16 AWG speaker wire, with a recommended 60A fuse (not included). The compact dimensions are 1.6\" x 4.3\" x 8.3\". Rockford Fosgate offers a full 2-year parts and labor warranty.","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52663526129976,"sku":"T400X4ad","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687614089.png?v=1784327726","url":"https:\/\/store.motormia.co\/products\/4-channel-amplifier-2","provider":"MOTORMIA","version":"1.0","type":"link"}
