Features and installation details

Picasso Nano Series 4Ch Amplifier

True Power in a Compact Chassis

Meet the Soundstream PN4‑1000D, part of the highly regarded Picasso Nano Series, designed to bring serious output in a form factor that defies expectations. Built for modern drivers and tight installs, this 1000-watt Class D 4-channel amplifier delivers clean, full-range audio whether you're running a factory head unit or a high-end aftermarket setup.

Despite its small size, this amp hits with real force. It's the perfect fit for under-seat or trunk setups in sport compacts, sedans, or even motorcycles and UTVs. What you sacrifice in space, you gain in clarity, control, and raw, consistent output.

Engineered for Clean, Controlled Sound

Thanks to a Pulse-Width Modulated MOSFET power supply and Class D circuit design, the PN4‑1000D maintains efficiency even at high volumes, reducing heat build-up and distortion. Whether you're powering a set of door speakers or bridging to a pair of subwoofers, this amp maintains sound integrity across all four channels.

Output Ratings:

• 140W x 4 @ 4 Ohms RMS
• 250W x 4 @ 2 Ohms RMS
• 500W x 2 @ 4 Ohms Bridged
• Max Power Output: 1000W

Flexible Install & Factory Integration

Don’t want to run a remote turn-on wire? No problem. The PN4‑1000D includes Automatic Hi-Level Signal Sensing Turn-On, allowing for seamless integration with OEM factory radios. Just connect via the high-level inputs, and the amp activates the moment music plays.

You can mount it under the front or rear seat and still retain enough airflow for proper ventilation. Even after extended high-volume sessions, the amp stays cool and consistent.

Built for Daily Abuse

The Picasso Nano is more than a small amp — it’s a full-featured solution:

• Adjustable Crossovers (High & Low-Pass): 35Hz–250Hz, 24dB/octave
• Input Sensitivity: 200mV–6V for easy signal matching
• 2 Ohm Stable and 4 Ohm Bridgeable
• Protection Circuitry: Thermal, overload, short-circuit

Unlike other so-called "compact amps" with weak internal components or inflated specs, the PN4‑1000D uses genuine, reliable MOSFETs and grounded Class D engineering. That means cleaner sound, longer lifespan, and zero gimmicks.

Why Choose the PN4‑1000D?

• Fits tight installs without compromise
• Works with stock or aftermarket head units
• No overheating after long sessions
• Zero distortion at high volume
• Trusted by pro installers and daily drivers
