It is intended for powering a pair of speakers or supporting a compatible subwoofer setup through stereo or bridged operation. With 2-ohm-stable stereo operation, it gives installers flexibility when matching compatible speaker loads.\u003c\/p\u003e\u003cp\u003eThis amplifier is suited to listeners upgrading beyond head-unit power and seeking adjustable control over low-frequency output. Its Class A-B design and full-range capability allow it to be used in systems focused on amplified speakers, bass reinforcement, or a combination of both. The selectable operating modes and adjustable controls help tailor the amplifier to the role it serves in the system.\u003c\/p\u003e\u003cp\u003eThe AT-3500S is rated for up to 3500 watts maximum output. A continuously variable low-pass crossover provides a 35 Hz to 160 Hz adjustment range for subwoofer-oriented setups, while the bass boost control offers adjustment from 0 to +18 dB. An included remote bass knob provides a convenient way to adjust bass level from the listening position.\u003c\/p\u003e\u003cp\u003eIts power section uses a MOSFET pulse-width-modulated power supply, and the amplifier includes soft turn-on operation. Nickel-plated RCA inputs and speaker-level inputs support connection to source units with either low-level preamp outputs or speaker-level outputs. The amplifier also uses a remote turn-on\/turn-off circuit for integration with a vehicle audio system.\u003c\/p\u003e\u003cp\u003eFor protection during operation, the AT-3500S includes thermal and speaker-short protection circuitry, along with power and protection LED indicators. Its heavy-duty aluminum-alloy heatsink is designed to help dissipate heat during use. This makes it a practical component for a properly wired, ventilated aftermarket audio installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Channel Design:\u003c\/strong\u003e Supports stereo speaker systems or a bridged mono configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Operation:\u003c\/strong\u003e Accommodates compatible low-impedance stereo speaker loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3500W Maximum Output:\u003c\/strong\u003e Provides a stated maximum-power rating for system planning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Crossover:\u003c\/strong\u003e Adjusts the low-pass point from 35 Hz to 160 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Bass Knob:\u003c\/strong\u003e Lets the listener adjust bass level from the cabin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e Helps protect against thermal and speaker-short fault conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AT-3500S uses a heavy-duty aluminum-alloy heatsink and a surface-mount amplifier format. Nickel-plated RCA connections are provided alongside speaker-level input capability. Power and protection LEDs provide at-a-glance operating-status feedback.\u003c\/p\u003e\u003cp\u003eInstall the amplifier on a secure surface with adequate airflow and keep it away from moisture and excessive heat. It requires connection to a 12V vehicle electrical system, including battery, ground, remote turn-on, input, and speaker wiring. Use stereo wiring with loads of 2 ohms or higher per channel, or use a 4-ohm-or-higher load when operating the amplifier bridged.\u003c\/p\u003e","brand":"Audiotek","offers":[{"title":"Default Title","offer_id":45614173618246,"sku":"AT-3500S","price":148.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/710ZJpJQ76S.jpg?v=1784359154","url":"https:\/\/audiowatt.store\/products\/audiotek-at-3500s-2-channel-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
