In Phase Car Audio IPA9701D Amplifier – 1 Ohm Stable 2400 Watts Monoblock with Subsonic Filte

• TRUE RMS POWER – (500W RMS x 1 @ 4 ohms, 800W RMS x 1 @ 2 ohms, 1200W RMS x 1 @ 1 ohms). All In Phase IPA in-car amplifiers go through numerous check points to ensure you get the true performance you are paying for
• STEALTH DESIGN WITH AN EDGE – A slim enclosure and the blackout design of the amplifier allows the unit to be camouflaged into your boot, whilst the intimidating LED blue lights will give your system that evil look
• IMPROVED CIRCUIT DESIGN – In Phase's new digital amplifier circuit senses its internal temperature and automatically moderates input level accordingly to prevent circuit shutdown. 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
• VARIABLE 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
• EASY FITTING AT HOME – The IPA series amps are not massive slabs of metal and plastic so their compact design ensures simple DIY fitting
