As part of the Overdrive Series, this 4-channel full-range Class-D amplifier provides high output and thermal stability, while remaining efficient under demanding conditions.\u003c\/p\u003e\n\u003cp\u003eDesigned for car audio setups where power distribution, clarity, and space all matter, the OD4-1800 is optimized for running full-range door speakers, midbass drivers, or tweeter arrays. With Class-D topology, this amp minimizes heat buildup and power strain without compromising dynamic range.\u003c\/p\u003e\n\u003cp\u003eWith OEM head units or an aftermarket deck, the OD4-1800 amplifier supports both high-level and low-level inputs. This makes it ideal for daily drivers, SQ-focused setups, or bass-intensive builds needing clean front-to-rear amplification. Its small chassis design and MOSFET power supply ensure install versatility, while protecting circuitry against thermal overload, shorts, and voltage spikes.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2-Ohm Stereo \u0026amp; 4-Ohm Bridged Full-Range Operation\u003c\/li\u003e\n\u003cli\u003eMilitary Grade PCB w\/PWM MOSFET Power Supply\u003c\/li\u003e\n\u003cli\u003eDirect Short, Thermal, \u0026amp; Overload Circuit Protection\u003c\/li\u003e\n\u003cli\u003eHigh\/Speaker Level \u0026amp; Low Level\/RCA Input\u003c\/li\u003e\n\u003cli\u003e4g Power Wire \u0026amp; 8g Speaker Wire Outputs\u003c\/li\u003e\n\u003cli\u003eVariable 12dB High \u0026amp; Low Pass Crossovers\u003c\/li\u003e\n\u003cli\u003e12dB Bass Boost Increases Low Octave Harmonics\u003c\/li\u003e\n\u003cli\u003eCompact and Efficient SMT PCB Design\u003c\/li\u003e\n\u003cli\u003eIndependent Gain Controls for Each Channel Pair\u003c\/li\u003e\n\u003cli\u003eBridgeable Channels for High-Power 2-Channel Operation\u003c\/li\u003e\n\u003cli\u003eHigh\/Low pass Filters for Tuning Door, Rear Fill, or Component Setups\u003c\/li\u003e\n\u003cli\u003e4-Gauge Power Input Terminals for Stable Current Delivery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Rating :\n\u003cul\u003e\n\u003cli\u003eMax Power : 1800 Watts\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 2Ω) : 225 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 4Ω) : 140 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power Bridged (4Ω) : 450 Watt x 2 Channel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eTHD : \u0026lt;0.3%\u003c\/li\u003e\n\u003cli\u003eBass Boost : 12dB\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity : 200mV - 8.0V\u003c\/li\u003e\n\u003cli\u003eFrequency Response : 20Hz - 20KHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio : ≥100dB\u003c\/li\u003e\n\u003cli\u003eCrossover (-12dB\/Oct)\n\u003cul\u003e\n\u003cli\u003eVariable High-Pass : 120Hz - 3KHz\u003c\/li\u003e\n\u003cli\u003eVariable Low-Pass : 50Hz - 250Hz\u003c\/li\u003e\n\u003cli\u003eVariable Sub-Sonic : N\/A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSpeaker Impedance : 2Ω - 8Ω\u003c\/li\u003e\n\u003cli\u003eFuse Rating : 25A x 2\u003c\/li\u003e\n\u003cli\u003eDimensions (L x W x H) : 14.0″ x 7.25″ x 2.3″ (355.6 x 184.15 x 58.42)mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Power Acoustik","offers":[{"title":"Default Title","offer_id":47260608004284,"sku":"OD4-1800","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/0741\/6508\/files\/OD4-1800_03799ddf-26df-4c40-a4be-9cf3e3167fc4.jpg?v=1786443414","url":"https:\/\/11thstreetelectronic.com\/products\/power-acoustik-od4-1800-1800-watts-max-power-4-channel-class-a-b-full-range-car-amplifier","provider":"11TH STREET ELECTRONIC INC","version":"1.0","type":"link"}
