Blast off with In Phase amplifiers, featuring advanced features like bass boost, variable subsonic filters, crossover networks, two-ohm stable designs, and more. Connectivity is great with RCA inputs and outputs and cast end caps that organize wiring. Plus, the massive heat sinks and tri-mode capability provide powerful, custom sound. Get a four or two channel design with a potent MOSFET power supply for single-amp or pavement-shaking solutions. Unmatched quality and power - the IPA range from In Phase is possibly the best car amplifier available. All of our amps are hand-assembled and go through 35 checkpoints for maximum performance. Our amps feature Subsonic filters to power your desired frequency range, Line in/out for multiple amplifiers, and dual-layer circuit boards. Experience true RMS power for a great sound. 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, Juice'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 2 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.
