Soundstream PN4.520D Picasso Nano Series 1040W Max Power 4-Channel Class-D Car Amplifier

Soundstream PN4.520D

The Soundstream PN4-520D Picasso Nano Amplifier seems too small to deliver real power—but size doesn’t dictate performance here. 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.

Built for cars, motorcycles, and tight installations, it mounts cleanly under seats or inside fairings—staying hidden while your sound system makes a strong impression.

Whether 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.

Thanks 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.

This 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.

And 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.
