It delivers 4x130W at 2 ohms, with fully bridgeable channels for flexible 2- or 4-channel setups. Both high and low-level inputs are supported, and input sensitivity is adjustable to suit various audio sources. Total harmonic distortion stays below 0.1% at 100Hz, while the frequency response spans 10Hz to 30kHz for detailed, interference-free sound. Intelligent energy management keeps idle consumption at just 1A, making this a smart upgrade for any car audio system.\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eChannels:\u003c\/strong\u003e 4\u003cbr\u003e\u003cstrong\u003eClass:\u003c\/strong\u003e D\u003cbr\u003e\u003cstrong\u003eTotal Power RMS:\u003c\/strong\u003e 520 W\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) @ 4 Ω, 1% THD:\u003c\/strong\u003e 70 W x 4\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) @ 2 Ω, 1% THD:\u003c\/strong\u003e 130 W x 4\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) Bridged @ 4 Ω, 1% THD:\u003c\/strong\u003e 260 W x 2\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) @ 4 Ω, 10% THD:\u003c\/strong\u003e 90 W x 4\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) @ 2 Ω, 10% THD:\u003c\/strong\u003e 180 W x 4\u003cbr\u003e\u003cstrong\u003eOutput Power (RMS) Bridged @ 4 Ω, 10% THD:\u003c\/strong\u003e 360 W x 2\u003cbr\u003e\u003cstrong\u003eMinimum Load Impedance:\u003c\/strong\u003e 4 Ch: 2 Ω; 2 Ch (Bridged): 4 Ω\u003cbr\u003e\u003cstrong\u003eDistortion (THD) @ 100 Hz, 4 Ω, 70% Power:\u003c\/strong\u003e 0.1%\u003cbr\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10 Hz - 30 kHz (-3 dB)\u003cbr\u003e\u003cstrong\u003eSignal-to-Noise Ratio (A-weighted):\u003c\/strong\u003e 100 dBA\u003cbr\u003e\u003cstrong\u003eDamping Factor @ 1 kHz, 4 Ω:\u003c\/strong\u003e 170\u003cbr\u003e\u003cstrong\u003eInput Sensitivity (Pre-In):\u003c\/strong\u003e Selectable: 1.5 \/ 3 \/ 4.5 V RMS\u003cbr\u003e\u003cstrong\u003eInput Sensitivity (Speaker-In):\u003c\/strong\u003e Selectable: 3 \/ 6 \/ 9 V RMS\u003cbr\u003e\u003cstrong\u003eInput Impedance (Pre-In):\u003c\/strong\u003e 15 kΩ\u003cbr\u003e\u003cstrong\u003eInput Type:\u003c\/strong\u003e PRE IN RCA\u003cbr\u003e\u003cstrong\u003ePower Supply Voltage:\u003c\/strong\u003e 7.5 - 15 VDC\u003cbr\u003e\u003cstrong\u003eIdling Current:\u003c\/strong\u003e 1 A\u003cbr\u003e\u003cstrong\u003eIdling Current When Off:\u003c\/strong\u003e 0.05 mA\u003cbr\u003e\u003cstrong\u003eMax Current Consumption @ 14.4 VDC, 2 Ω:\u003c\/strong\u003e 27 A\u003cbr\u003e\u003cstrong\u003eRemote Input:\u003c\/strong\u003e 7 - 15 VDC (1 mA)\u003cbr\u003e\u003cstrong\u003eFuse:\u003c\/strong\u003e 30 A\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.33 kg\u003cbr\u003e\u003cstrong\u003eAdjustable Crossover:\u003c\/strong\u003e No\u003cbr\u003e\u003cstrong\u003eCEA Output Power @ 4 Ω, 1% THD+N, 14.4 V:\u003c\/strong\u003e 70 W x 4\u003cbr\u003e\u003cstrong\u003eCEA S\/N Ratio (ref. 1W output):\u003c\/strong\u003e 85 dBA\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":54094719451473,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/1406293103_AP4D_emo_800_505.png?v=1781799204","url":"https:\/\/shoponyxac.co.uk\/products\/audison-prima-ap4-d-4-channel-class-d-car-amplifier-520w","provider":"Onyx Auto Care","version":"1.0","type":"link"}
