In Phase IPA5001D 5000W Subwoofer Amplifier

The In Phase IPA series of amplifiers is quite possibly the premier choice for car audio today. Every amp is hand-assembled, with 35 different checkpoints ensuring top-tier quality. And with 1-ohm stability, trimode capability and smart protection circuits, they can handle any job. Plus, massive heat sinks and high air-to-volume ratios bear the brunt of the work, while cast end caps keep everything neat and orderly. Forced air cooling on the ultra-powerful models ensures maximum performance. British Design - All In Phase amps are designed in the UK utilising over 30 years of audio experience to create a sound that is right for you. Improved Circuit Design - To prevent circuit shutdown, In Phase's new digital amplifier circuit, senses its internal temperature and automatically moderates input level accordingly. Stable, durable circuitry lessens the risk of high input power for the unit to achieve 1 Ω connection. This design enhances the flexibility to connect multiple subwoofers to a system.Low Pass Filter - For extra flexibility, a variable LPF makes audio frequency more adjustable according to subwoofer characteristics and personal listening preferences. The LPF is adjustable from 30 Hz to 250 Hz.
