Despite its ultra-compact chassis, this amplifier delivers up to 520 watts of RMS power, optimized across 4, 3, or 2 channels depending on your configuration needs.\u003c\/p\u003e\n\u003cp\u003eBuilt for cars, motorcycles, and tight installations, it mounts cleanly under seats or inside fairings—staying hidden while your sound system makes a strong impression.\u003c\/p\u003e\n\u003cp\u003eWhether it’s the front or back seat, the PN4-520D slides into place with minimal clearance, leaving room for ventilation. Even after extended high-volume playback, this amp stays cool and stable, eliminating common heat issues seen in other compact class D models.\u003c\/p\u003e\n\u003cp\u003eThanks to integrated high-pass and low-pass crossovers at 80 Hz and a subsonic filter ranging from 10–50 Hz, your music stays tight, distortion-free, and full of clarity—regardless of source.\u003c\/p\u003e\n\u003cp\u003eThis amplifier is engineered with real-world usability in mind. It uses a true MOSFET PWM power supply, avoiding the pseudo-tech found in lower-end models. Combined with Class D circuitry, it ensures efficient output without compromising fidelity.\u003c\/p\u003e\n\u003cp\u003eAnd when using a factory or stock radio, the PN4-520D doesn’t require a remote wire. Its Automatic Hi-Level Signal Sensing Turn-On detects speaker-level signals and activates the amp instantly—making installation simpler and more intuitive.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-Compact 4-Channel Class D Amplifier\u003c\/li\u003e\n\u003cli\u003eApplying new concept \"Low-Heat Producing Circuit\"\u003c\/li\u003e\n\u003cli\u003eMOSFET PWM Power Supply \u0026amp; Thermal-Safe Design\u003c\/li\u003e\n\u003cli\u003eHigh-Level Sensing with Automatic Turn-on\u003c\/li\u003e\n\u003cli\u003e80Hz 12dB\/oct HP\/LP Crossover + Subsonic Filter\u003c\/li\u003e\n\u003cli\u003eBridgeable Channels for Subwoofer Use\u003c\/li\u003e\n\u003cli\u003ePerfect for Under-Seat or Motorcycle Fairing Installs\u003c\/li\u003e\n\u003cli\u003eNI 4Gauge Input Block Type Power Terminal and 4Gauge out Speaker Block Type Terminals\u003c\/li\u003e\n\u003cli\u003eSMD Technology, Double Sided FR-4 PC Board\u003c\/li\u003e\n\u003cli\u003eUltra Slim Size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePicasso Nano Series 4-Channel Class-D Amplifier\u003c\/li\u003e\n\u003cli\u003ePower Rating:\n\u003cul\u003e\n\u003cli\u003eMax Power : 1040 Watts\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 2Ω) : 130 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 4Ω) : 100 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power Bridged (@ 4Ω) : 260 Watt x 2 Channel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity : 200mV - 6.0V\u003c\/li\u003e\n\u003cli\u003eTHD : \u0026lt;0.1%\u003c\/li\u003e\n\u003cli\u003eFrequency Response : 10Hz - 300Hz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio : 104dB\u003c\/li\u003e\n\u003cli\u003eOperation Voltage : 9.0VDC - 16.0VDC\u003c\/li\u003e\n\u003cli\u003eBass Boost : N\/A\u003c\/li\u003e\n\u003cli\u003eBass Boost Frequency : N\/A\u003c\/li\u003e\n\u003cli\u003eCrossover (-12dB\/Oct):\n\u003cul\u003e\n\u003cli\u003eHigh Pass Filter : Fixed 80Hz\u003c\/li\u003e\n\u003cli\u003eLow Pass Filter : Fixed 80Hz\u003c\/li\u003e\n\u003cli\u003eSubsonic Filter : \u003cspan\u003e10Hz - 50Hz\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eFuse Rating : 30A x 2\u003c\/li\u003e\n\u003cli\u003eDimensions : 9.25\"L x 8.25\"W x 2.75\"H\u003c\/li\u003e\n\u003cli\u003eRemote Gain Control : N\/A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Soundstream","offers":[{"title":"Default Title","offer_id":47260614820028,"sku":"PN4-520D","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/0741\/6508\/files\/PN4.520D_00da29fd-d9dd-4f7c-bb8d-97254c485e4e.jpg?v=1786443558","url":"https:\/\/11thstreetelectronic.com\/products\/soundstream-pn4-520d-520w-4-channel-class-d-picasso-series-compact-amplifier","provider":"11TH STREET ELECTRONIC INC","version":"1.0","type":"link"}
