It can drive front and rear speakers from four channels or support bridged channel pairs where a system calls for higher output. This makes it a practical choice for listeners replacing low-power factory amplification or building a multi-speaker system around an aftermarket source unit.\u003c\/p\u003e\u003cp\u003eRated output is 150 watts RMS per channel at 4 ohms and 300 watts RMS per channel at 2 ohms. For systems using bridgeable channel pairs, it is rated at 600 watts RMS x 2 at 4 ohms. Its 10 Hz to 22 kHz frequency response supports full-range speaker applications as well as filtered subwoofer-duty channel pairs.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a Class A\/B architecture with a PWM MOSFET power supply. An aluminum heat sink helps dissipate heat, while the integrated electronic crossover lets the installer direct appropriate frequencies to connected speakers. Variable high-pass and low-pass filtering provide useful control when combining component speakers, coaxials, or subwoofers in one installation.\u003c\/p\u003e\u003cp\u003eSignal integration is flexible for many aftermarket and factory-radio upgrade paths. The ZG-1200.4 provides RCA inputs, speaker-level inputs, and a 2-channel or 4-channel input-mode selection. Its 0.2 to 6V input-sensitivity range allows the gain structure to be matched to the source unit rather than used as a volume control.\u003c\/p\u003e\u003cp\u003eThis amplifier fits well in a system that needs one chassis to power four speakers, or two speakers plus a bridged subwoofer channel pair. A selectable full-range, high-pass, or low-pass crossover arrangement helps tailor the output to the connected drivers. Proper impedance matching, secure power wiring, ventilation, and careful gain setup are important for reliable operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Design:\u003c\/strong\u003e Powers up to four speaker channels from one amplifier chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Outputs:\u003c\/strong\u003e Supports two bridged 4-ohm channel-pair outputs when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass A\/B Amplification:\u003c\/strong\u003e Delivers full-range amplification for speaker-system upgrades.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters help match output to drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Signal Inputs:\u003c\/strong\u003e Includes RCA and speaker-level input options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum Heat Sink:\u003c\/strong\u003e Helps manage heat during installed operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ZG-1200.4 uses an aluminum heat sink, angled molded connection terminals, and nickel-plated RCA input connections. Its PWM MOSFET power supply is designed to provide stable amplifier power, while onboard LED protection diagnostics monitor overload and speaker-short conditions. The amplifier measures approximately 14.25 inches long, 8.25 inches wide, and 2.375 inches high.\u003c\/p\u003e\u003cp\u003eMount the amplifier on a secure, dry surface with sufficient airflow and keep it away from moisture. Use 4 AWG power and ground connections, a 50A fuse, and 12 AWG speaker wiring at the amplifier terminals; the main power cable should be fused within 18 inches of the battery. Disconnect the vehicle battery before installation, set gain low before initial setup, and use 4-ohm loads for bridged operation.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631954092102,"sku":"ZG-1200-4","price":253.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51QfslKLfSL.jpg?v=1784390541","url":"https:\/\/audiowatt.store\/products\/hifonics-zg-1200-4-4-channel-class-ab-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
