4-Channel Car Amplifier

The DLS Performance Evolution PE4.150 is a powerful 4-channel class D amplifier, designed as the next step after the highly recognizable P series amplifiers from DLS. It combines strong performance with stable control and a sound that is open, balanced, and easy to use over time. The PE4.150 is built for modern sound systems and active solutions, where predictability and musicality are at least as important as output power.

• 4-channel class D amplifier
• 4x150W RMS at 2 Ω, 4x100W RMS at 4 Ω
• Bridge mode start at 2 x 300 W RMS at 4 Ω
• Stable and controlled power supply
• High-level input with Smart Load and automatic activation
• Adjustable high and low pass filters
• EMI optimized design for modern cars
• Compact form with high efficiency

The PE4.150 delivers enough power in a controlled and predictable manner. Speakers remain stable even when volume increases, offering better dynamics and a clearer structure in the sound image. This makes the amplifier suitable both for traditional front systems and for more advanced active installations.

The sound is tuned for natural reproduction. Details are clear without being harsh, and dynamics are present without being aggressive. The result is an open and balanced sound that works equally well at low and higher listening levels.

Integration into modern cars is a key design element. The high-level input with Smart Load ensures the amplifier operates steadily even with original systems that monitor impedance. Automatic power on and off simplifies installation and ensures the system behaves consistently in daily use.

With adjustable high and low pass filters, it is easy to tailor the amplifier to the speakers and system layout. The settings are logical and easily understood, facilitating quick adjustment and providing a result that is easy to fine-tune.
