Connect the chassis ground to clean bare metal close to the amplifier, set the input level from minimum, and tune crossover controls carefully to avoid distortion.\u003c\/p\u003e","brand":"HIFONICS","offers":[{"title":"Default Title","offer_id":45776302342335,"sku":"ZG-1200-1D","price":106.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/6252\/4351\/files\/51HjiCgPgvL_13c78bf9-760d-433e-ab79-5c4dda8b40d8.jpg?v=1782490476"},{"product_id":"hifonics-zg-1200-2","title":"Hifonics ZG-1200.2 2-Channel Class A\/B Car Amplifier","description":"\u003cp\u003eThe Hifonics ZG-1200.2 is a two-channel car audio amplifier designed to add substantial external power to a speaker system or a compatible subwoofer setup. It is a Class A\/B model with stereo and bridged-mono operating options, making it suitable for a range of upgrade paths. Use it when a factory or aftermarket receiver needs more output capability than its built-in amplifier can provide.\u003c\/p\u003e\u003cp\u003eIn stereo operation, the ZG-1200.2 is rated for 300 watts RMS per channel at 4 ohms or 600 watts RMS per channel at 2 ohms. It can also be bridged to deliver 1,200 watts RMS into a 4-ohm mono load. These configurations allow it to support two speakers, two subwoofers within its impedance limits, or one appropriately matched bridged subwoofer.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a PWM MOSFET power supply with Hifonics Simpatico Coil Design to support stable power delivery. Its Class A\/B architecture is paired with a low-noise preamplifier circuit and a stated 10 Hz to 22 kHz frequency response. Variable crossover controls and bass adjustment help tailor the amplifier for full-range speakers or a subwoofer-focused installation.\u003c\/p\u003e\u003cp\u003eIntegration is practical for both aftermarket and factory audio systems. The ZG-1200.2 provides RCA inputs along with speaker-level inputs, so it can accept either low-level preamp signal or a factory speaker-level signal. RCA outputs are also provided for passing signal to an additional amplifier in a larger system.\u003c\/p\u003e\u003cp\u003eBuilt for conventional vehicle installations, the amplifier uses an aluminum heat sink and angled connection terminals for accessible wiring. LED power and protection diagnostics help identify operating or fault conditions, including overload and speaker-short protection.
