Its single-channel configuration concentrates output into a dedicated bass channel, making it suited to installations where low-frequency performance is the priority. It provides selectable power ratings for 1-, 2-, and 4-ohm subwoofer loads.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for drivers building or upgrading a vehicle bass system with a compatible subwoofer or wired subwoofer group. Its mono-only design keeps system planning straightforward when using a separate amplifier or factory power for full-range speakers. Speaker-level inputs can also help integrate the amplifier into systems without a traditional RCA preamp output.\u003c\/p\u003e\u003cp\u003eThe ZD-3350.1D uses a PWM MOSFET power supply and Class D topology, combining high-output bass amplification with a relatively compact amplifier footprint. An aluminum heat sink is used to help dissipate heat during operation. The amplifier also includes soft-start turn-on and protection diagnostics for overload and speaker-short conditions.\u003c\/p\u003e\u003cp\u003eOnboard controls provide practical adjustment for a subwoofer system. The variable low-pass crossover operates from 50 to 250 Hz, while the subsonic filter adjusts from 15 to 40 Hz. A variable bass boost control provides 0 to 12 dB of adjustment, and the built-in bass control supports convenient level adjustment.\u003c\/p\u003e\u003cp\u003eInstallation-focused details include nickel-plated, high-temperature, impact-resistant RCA inputs and angled molded connection terminals for power, ground, and speaker wiring. DC Signal Sense can turn the amplifier on when it detects a signal at the RCA inputs, eliminating the need for a remote turn-on lead when that setup is appropriate. A wired bass remote is included for accessible bass-level control after installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDedicated Mono Channel:\u003c\/strong\u003e Focuses the amplifier on subwoofer and low-frequency applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass D Design:\u003c\/strong\u003e Delivers efficient mono amplification in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Lets you set the upper frequency range sent to the subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Subsonic Filter:\u003c\/strong\u003e Helps limit very low frequencies below the selected cutoff.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC Signal Sense:\u003c\/strong\u003e Can activate the amplifier from an RCA input signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Provides convenient adjustment of bass level from the cabin.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ZD-3350.1D has a black Zeus Delta chassis with an aluminum heat sink, molded connection terminals, and nickel-plated RCA inputs. Its end-panel LED protection diagnostics provide visible status indication for overload and speaker-short protection. The amplifier uses a compact digital Class D layout intended to conserve mounting space compared with larger traditional amplifier designs.\u003c\/p\u003e\u003cp\u003eUse this amplifier with a subwoofer or subwoofer wiring arrangement that presents a supported 1-, 2-, or 4-ohm load. The manufacturer lists 2 AWG connections for the 12V and ground terminals, 12 AWG speaker-terminal wiring, and an external 175A fuse. Mount it securely with adequate ventilation, run appropriately fused power wiring directly from the battery, and set crossover, subsonic-filter, gain, and bass controls to suit the connected subwoofer system.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631946489926,"sku":"ZD-3350-1D","price":386.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71TcjZWw7XL.jpg?v=1784390344","url":"https:\/\/audiowatt.store\/products\/hifonics-zd-3350-1d-zeus-delta-mono-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
