It can be used to power front and rear speakers independently or configured for two bridged channels with compatible 4-ohm loads. Its full-range design makes it a practical option for multi-speaker upgrades where an aftermarket or factory source unit needs more output capability.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building a clearer, more controlled speaker system without using a large chassis amplifier. It provides manufacturer-rated output of 170 watts per channel at 4 ohms or 335 watts per channel at 2 ohms. For bridged applications, it is rated for 675 watts per channel across two channels at 4 ohms.\u003c\/p\u003e\u003cp\u003eAdjustable high-pass and low-pass crossovers allow the ZD-1350.4D to be matched to the role of the speakers it powers. The crossover ranges from 50 Hz to 250 Hz with a 12 dB-per-octave slope, helping separate bass and higher-frequency duties in a system. A built-in bass control is also provided for output adjustment.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a PWM MOSFET power supply with a Simpatico coil design to maintain operating voltage through the output stage. Its Class D topology and aluminum heat sink support efficient operation in a compact enclosure. A low-noise preamplifier circuit is designed to accept low-level source signals with minimal distortion.\u003c\/p\u003e\u003cp\u003eFor installation flexibility, the ZD-1350.4D supports four-channel, full-range, and bridged operation modes. DC Signal Sense can turn the amplifier on when a signal is received at the RCA inputs, eliminating the need for a remote turn-on wire when that setup is appropriate. LED diagnostics provide illuminated indication for overload and speaker-short protection conditions.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Design:\u003c\/strong\u003e Powers four speakers independently or supports two bridged channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Operation:\u003c\/strong\u003e Delivers up to 335 watts per channel at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Electronic Crossovers:\u003c\/strong\u003e Helps tailor frequency ranges for speakers or subwoofer applications.\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\u003ePWM MOSFET Power Supply:\u003c\/strong\u003e Supports stable power delivery through the amplifier circuitry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED Protection Diagnostics:\u003c\/strong\u003e Provides visible overload and speaker-short status indication.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ZD-1350.4D has a black compact chassis with an aluminum heat sink for heat dissipation. Its RCA inputs are nickel-plated and specified as high-temperature, impact-resistant, and erosion-resistant. Secure molded terminals are angled for access and organized power, ground, and speaker wiring.\u003c\/p\u003e\u003cp\u003eUse 4 AWG cable at the power and ground terminals, a properly fused direct battery connection, and a secure bare-metal chassis ground. The amplifier uses an external 60A fuse and accepts up to 12 AWG speaker wire at its speaker terminals. Select four 2-ohm-or-higher speaker loads for individual channels, or use 4-ohm loads when bridging channels; install in a secure location with adequate ventilation.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631938363462,"sku":"ZD-1350-4D","price":321.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71cSYI7YY7L.jpg?v=1784390176","url":"https:\/\/audiowatt.store\/products\/hifonics-zd-1350-4d-4-channel-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
