    Product Details

    Car amplifiers are the heart of a system and need be of the best quality available for your budget. All Inphase IPA car amplifiers are hand assembled and go through 35 different check points to ensure you get the best possible car amplifier today. 

    With One and Two OHM stable designs, trimode capability and clever protection circuits, these hand-built powerhouses will take anything you throw at them. Massive heat sinks with a high surface area to volume ratios and cast end caps to hide the wiring connections and keep things controlled – helped by forced air cooling on the real bass monsters. 

    The newly designed IPA8701D, IPA8704D, IPA9701D and IPA9704D now incorporate digital technology into their design, these amps are direct competition to the Pioneer GM-D amplifiers.

    The IPA series amplifiers are designed for performance in a performance build. So there is no speaker level input, these are designed to fit with an aftermarket headunit. But you do not need to panic, you can use a line out converter to fit this amplifier to your factory system. For fitting the IPA series amp to a factory system we advise using the In Phase SRCAPro or for higher performance, the In Phase SRC6.

    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 on the Monoblock IPA Amp and 2Ω  for the 4 channel IPA Amps. 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 50 Hz to 250 Hz.

    Small Footprint

    The IPA series amps are not massive slabs of metal/plastic. They are compactly designed ensuring easy fitting. 

    True RMS Power

    The In Phase IPA9701D/IPA9704D go through numerous check points to ensure you get the true performance you are paying for. 

    Stealth Design

    Along with the slim design, the blackout design of these amplifiers ensure this amp camouflages into your boot, the intimidating LED blue lights in a blackout area, will give your system that evil look
