Engineered to deliver serious full-range power from a remarkably small footprint, this amplifier pushes a solid 60 watts RMS per channel at 4 ohms, and up to 90 watts RMS at 2 ohms. For those requiring even more power for larger speakers or subwoofers, the APEV-400.4 is fully bridgeable, allowing you to route 180 watts RMS to two channels. Measuring just under 6 inches in length, this micro-sized amplifier can be easily tucked away under seats, behind dashboards, or inside motorcycle fairings, making it the perfect solution for cars, trucks, and powersports vehicles with limited installation space.\u003cbr\u003e\u003cbr\u003e\n\nDespite its small size, the APEV-400.4 is packed with the tuning capabilities and protective features expected from a full-sized amplifier. It features built-in 90Hz High-Pass and Low-Pass filters, giving you the control needed to cleanly separate frequencies and ensure your component speakers or subwoofers perform with maximum clarity and zero distortion. Adjustable input sensitivity (0.2V to 3V) allows for seamless integration with both factory and aftermarket head units. Furthermore, the amplifier includes robust circuitry with 9V undervoltage protection, ensuring stable, reliable performance and safeguarding your audio investment during demanding electrical loads.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003eKey Features\u003c\/b\u003e\u003cbr\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eUltra-Compact Class-D Design\u003c\/b\u003e: Highly efficient digital topology delivers massive power from a micro-sized chassis (5.9\" x 3.05\" x 1.97\") that fits almost anywhere.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBridgeable Output\u003c\/b\u003e: Can be bridged to provide a powerful 180 watts RMS to two channels, perfect for driving a pair of subwoofers or high-power components.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBuilt-In Crossovers\u003c\/b\u003e: Features dedicated 90Hz High-Pass and Low-Pass filters to easily tune your audio signal for optimal speaker efficiency and crisp sound.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eAdjustable Input Sensitivity\u003c\/b\u003e: Variable gain control from 0.2V to 3V allows for precise level matching with a wide variety of aftermarket and factory radios.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFull Range Audio\u003c\/b\u003e: Reproduces the entire audible spectrum (20Hz to 20kHz), making it versatile enough to power tweeters, midrange drivers, and subwoofers alike.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eAdvanced Protection Circuitry\u003c\/b\u003e: Built-in undervoltage protection (9V) automatically protects the amplifier and your vehicle's charging system during voltage drops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cb\u003eSpecifications\u003c\/b\u003e\u003cbr\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eAmplifier Class\u003c\/b\u003e: Class-D Full Range\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eChannel Configuration\u003c\/b\u003e: 4 \/ 3 \/ 2 Channels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eRMS Power @ 4 Ohms\u003c\/b\u003e: 60 Watts x 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eRMS Power @ 2 Ohms\u003c\/b\u003e: 90 Watts x 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBridged RMS Power @ 4 Ohms\u003c\/b\u003e: 180 Watts x 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFrequency Response\u003c\/b\u003e: 20 Hz – 20 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCrossover Filtering\u003c\/b\u003e: 90 Hz HPF \/ 90 Hz LPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eSignal-to-Noise Ratio\u003c\/b\u003e: \u0026gt;80 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eInput Sensitivity\u003c\/b\u003e: 0.2V – 3.0V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eOperating Voltage\u003c\/b\u003e: 9V – 16V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eDimensions\u003c\/b\u003e: 5.9\" (L) x 3.05\" (W) x 1.97\" (H)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Audiopipe","offers":[{"title":"Default Title","offer_id":67861397012629,"sku":"APEV-400.4","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0482\/2174\/9397\/files\/APEV4004_2.jpg?v=1792275956","url":"https:\/\/lifeafterbass.shop\/products\/audiopipe-apev-400-4-full-range-class-d-transistor-car-amplifier-4-x-90w-rms-2-ohm","provider":"LifeAfterBass","version":"1.0","type":"link"}
