It is designed for systems that need more output flexibility than a head unit's built-in amplifier can provide. The amplifier is rated at up to 1800 watts maximum power and supports stereo, bridged, and tri-mode system configurations.\u003c\/p\u003e\u003cp\u003eThis Class A\/B model is intended for listeners building a basic speaker upgrade, a subwoofer-focused setup, or a mixed car audio system. Its 2-ohm-stable design gives installers more options when matching compatible speaker loads. The full-range design also allows it to be used beyond dedicated bass duties when configured appropriately.\u003c\/p\u003e\u003cp\u003eThe AT-1800S provides a continuously variable low-pass crossover and bass-boost adjustment for tailoring low-frequency output. An included remote subwoofer control gives the driver convenient access to bass-level adjustment from the cabin. Variable input gain helps match the amplifier to the output level of the connected source unit.\u003c\/p\u003e\u003cp\u003eFor source integration, the amplifier offers nickel-plated RCA inputs as well as speaker-level inputs. This supports use with aftermarket receivers that provide RCA preouts and with systems that need a high-level input connection. A remote turn-on\/turn-off circuit is also included for coordinated amplifier operation with the vehicle audio system.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a MOSFET pulse-width-modulated power supply and includes thermal and speaker-short protection circuitry. Power and protection LED indicators provide a quick operating-status reference. These features make the AT-1800S a practical component for a planned car audio upgrade when matched with compatible speakers, wiring, and source equipment.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Channel Class A\/B Design:\u003c\/strong\u003e Supports stereo amplification for speakers or a bridged configuration for a compatible load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Stable Operation:\u003c\/strong\u003e Accommodates compatible low-impedance speaker wiring configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1800-Watt Maximum Rating:\u003c\/strong\u003e Provides the manufacturer-marketed maximum power figure for system planning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Bass Control:\u003c\/strong\u003e Lets the driver adjust subwoofer-level output from the cabin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Supports speaker-level wiring and RCA source connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection and Status LEDs:\u003c\/strong\u003e Helps identify power status and protection activation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AT-1800S uses a heavy-duty aluminum-alloy heat sink to support heat dissipation during operation. Its Class A\/B amplifier architecture, MOSFET power supply, and front-panel control layout are designed for conventional mobile-audio installations. Power and protection LED indicators provide visible status feedback.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a dry, ventilated location with clearance around the heat sink. Connect it through either the nickel-plated RCA inputs or speaker-level inputs, then set gain, crossover, and bass-boost controls to suit the connected speakers or subwoofers. Confirm final speaker impedance and bridged or tri-mode wiring with the amplifier documentation before powering the system.\u003c\/p\u003e","brand":"Audiotek","offers":[{"title":"Default Title","offer_id":45614105002054,"sku":"AT-1800S","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/719mwjbqZCS.jpg?v=1784358992","url":"https:\/\/audiowatt.store\/products\/audiotek-at-1800s-2-channel-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
