Its mono-only configuration concentrates output to one speaker system, making it suited to powering a compatible subwoofer setup. The compact chassis helps it fit into a range of vehicle audio installations where amplifier space is limited.\u003c\/p\u003e\u003cp\u003eWith rated output of 1 x 1,350 watts at 1 ohm, 1 x 675 watts at 2 ohms, and 1 x 350 watts at 4 ohms, the ZD-1350.1D offers flexibility for matching a compatible subwoofer load. Its 15 Hz to 250 Hz frequency response and adjustable low-pass crossover support bass-focused system tuning. A variable subsonic filter and bass boost provide additional adjustment for the installed enclosure and listening preferences.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a PWM MOSFET power supply with Hifonics' Simpatico Coil Design to support stable power delivery through its output devices. Class D topology is used for efficient operation in a compact footprint. An aluminum heat sink is built into the chassis to help dissipate heat during operation.\u003c\/p\u003e\u003cp\u003eFor integration with a variety of source units, the ZD-1350.1D includes RCA inputs and speaker-level audio inputs. Its low-noise preamplifier circuit is designed to accept low-voltage signal from the source unit with minimal distortion. The input sensitivity is adjustable from 0.2 to 6 volts for proper gain matching.\u003c\/p\u003e\u003cp\u003eThe ZD-1350.1D is a practical choice for a subwoofer upgrade that needs a dedicated mono amplifier with built-in tuning controls. Secure molded, angled terminals help organize power, ground, and speaker wiring. DC Signal Sense can automatically switch the amplifier on when a signal is detected at the RCA inputs, reducing the need for a separate remote turn-on lead when that feature is enabled.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Class D Design:\u003c\/strong\u003e Provides a dedicated single-channel platform for compatible subwoofer systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Power Capability:\u003c\/strong\u003e Delivers rated output at 1-, 2-, or 4-ohm loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Crossover:\u003c\/strong\u003e Adjusts the bass passband from 50 Hz to 250 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Offers adjustment from 15 Hz to 40 Hz for system tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Signal Sense:\u003c\/strong\u003e Can activate the amplifier from a detected RCA input signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Includes remote bass-level control for convenient adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ZD-1350.1D uses a black compact chassis with an aluminum Hifonics heat sink for heat dissipation. Its RCA inputs are nickel-plated, high-temperature, and impact-resistant. Angled molded connection terminals are designed to provide accessible power, ground, and speaker connections while maintaining a clean wiring profile.\u003c\/p\u003e\u003cp\u003eInstall the amplifier on a secure surface with adequate ventilation and do not mount it upside down. The manufacturer specifies 4 AWG power and ground terminals, 12 AWG speaker terminals, and an external 80A fuse. Match the connected speaker load and power handling to the amplifier's rated output, then set gain, crossover, subsonic filter, and bass boost carefully for the system.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631937282118,"sku":"ZD-1350-1D","price":237.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/713IdTMXmgL.jpg?v=1784390136","url":"https:\/\/audiowatt.store\/products\/hifonics-zd-1350-1d-mono-block-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
