It provides dedicated amplification for front and rear speakers along with a low-frequency channel for a subwoofer. This makes it a practical option for vehicle audio upgrades that need both cabin sound and bass without adding separate amplifiers.\u003c\/p\u003e\u003cp\u003eFor full-range channels, the S91100.5D is rated at 90 watts RMS x 4 at 4 ohms or 150 watts RMS x 4 at 2 ohms. Its subwoofer section is rated at 150 watts RMS x 2 at 4 ohms or 250 watts RMS x 1 at 2 ohms. The front or rear full-range channels can also be bridged to provide 300 watts RMS x 2 at 4 ohms, while the subwoofer channels can be bridged for 500 watts RMS x 1 at 4 ohms.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a full PWM power supply and full-range Class-D topology to combine multi-channel output with a compact 2-inch-tall chassis. It has a 10.0 to 17.0 VDC operating threshold and an idle-current specification of 0.7A. Its measured specification set includes 0.03% THD at 1 kHz and 4 ohms, plus an A-weighted signal-to-noise ratio of -96.7 dBA at full power.\u003c\/p\u003e\u003cp\u003eSystem tuning is supported by selectable full-range, high-pass, and low-pass crossover modes for channels 1 through 4. Variable high-pass and low-pass crossover adjustments cover 35 Hz to 350 Hz at 12 dB per octave. A variable bass boost and phase control allow the low-frequency output to be adjusted for the subwoofer installation and listening preferences.\u003c\/p\u003e\u003cp\u003eThe S91100.5D works with aftermarket head units through RCA connections and can also accept speaker-level input for many factory-radio integrations. Its input configuration can accept two-, four-, or five-channel input arrangements, and selectable REM, DC-offset, and VOX turn-on modes add installation flexibility. A wired bass remote is included for convenient subwoofer-level adjustment from the cabin.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Channel System Power:\u003c\/strong\u003e Runs front, rear, and subwoofer channels from one amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Range Class-D Topology:\u003c\/strong\u003e Delivers efficient multi-channel amplification in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stereo Stability:\u003c\/strong\u003e Supports compatible stereo speaker loads down to 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Channel Capability:\u003c\/strong\u003e Allows higher-power configurations with 4-ohm bridged loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Signal Integration:\u003c\/strong\u003e Accepts RCA or speaker-level input signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Enables convenient adjustment of subwoofer output level.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe amplifier has a black Stroker Series enclosure with a top-mounted illuminated logo, top-access controls, and status\/protection indication. Its full PWM supply, 4-layer PCB construction, and compact layout are intended for vehicle audio installations where space and heat management matter. The chassis measures 14.1 x 7.25 x 2.0 inches.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely to a solid vehicle panel or amplifier rack, with adequate ventilation and access to its controls and connections. Use a properly fused power lead within 18 inches of the battery, match the ground-wire gauge to the power wire, and keep signal cables separated from power wiring where possible. The amplifier accepts up to 4 AWG power and ground cable, while the manufacturer manual specifies a minimum of 8 AWG and lists a 90A battery fuse rating for this model.\u003c\/p\u003e","brand":"Cerwin Vega","offers":[{"title":"Default Title","offer_id":45616069705798,"sku":"CER-S9750-1D","price":564.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51dhARrQlnL.jpg?v=1784368513","url":"https:\/\/audiowatt.store\/products\/cerwin-vega-s91100-5d-5-channel-class-d-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
