{"product_id":"400-watt-4-channel-amplifier-1","title":"400 Watt 4-Channel Amplifier","description":"The Rockford Fosgate PM400X4 is a 400 Watt, 4-channel amplifier engineered for demanding motorsport and marine environments. It utilizes advanced Class-A\/B topology for high dynamic power and exceptional sound quality, with a conformal coated PC board to protect against dust, UV, temperature, water, corrosion, and vibration, aligning with Rockford Fosgate's Element Ready™ standard.\n\nThis amplifier is ideal for versatile audio configurations, including 4-way front-stage\/rear-fill or 3-way front-stage\/subwoofer systems. It offers an on-board Punch EQ with up to +18dB boost at 45Hz and 12dB\/octave Butterworth crossovers (high-pass\/low-pass\/all-pass) adjustable from 50Hz to 250Hz, allowing for precise audio tuning. Features like C.L.E.A.N. Set-up with input\/output clip LEDs, muted turn-on, and high-level input capability with an Auto Turn-On circuit facilitate easy integration and optimal performance.\n\nBuilt with a cast aluminum heatsink and Dynamic Thermal Management (DTM), the PM400X4 efficiently dissipates heat. It also includes protection features such as over current, short circuit, and NOMAD (real-time analog computer) to safeguard against speaker wire shorts and low impedances. The amplifier is CTA-2006 compliant, ensuring its power ratings are accurate.\n\nSpecifications include 50 Watts RMS x 4 @ 4-Ohm, 100 Watts RMS x 4 @ 2-Ohm, and 200 Watts RMS x 2 bridged @ 4-Ohm. It operates on a 9-16 VDC range and requires an 8 AWG to 4 AWG power wire gauge and a 60A recommended fuse. The unit dimensions are 2.38\" x 7.76\" x 11.03\".","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":52872746565944,"sku":"PM400X4","price":519.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/400-watt-4-channel-amplifier-1","provider":"MOTORMIA","version":"1.0","type":"link"}
