Key Features

InPhase 1 Ohm Stable 1600 Watts Monoblock with Subsonic Filter - In Phase Car Audio IPA8701D

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 30 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 IPA8701D/IPA8704D 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 amplfiiers ensure this amp camoflages into your boot, the intimidating LED blue lights in a blackout area, will give your system that evil look.

Impressive amp, clear instructions
Pavilion on 26/10/2021 5 star rating

Got this amp to power my Vibe 12" Slick High Output Sub Box. The power output is INSANE! The tunability is equally as impressive. The logo has a cool blue LED that lights up when its on, and it's not too big. The instructions were very easy to follow and setup was very quick

Small and powerful
Papa J on 31/08/2021 5 star rating

  • Question: 12 September 2021
    Hi,
    Interested in running a pioneer tsa300d4 sub off this amp. the RMS will match perfectly at 2ohm, however I’ve read other people are running 2 500w rms subs off this amp at 2ohm? Can it be done?

    Answer: 
    Hi there,

    2 500W rms subs cant be run through this amplifier.
    Also, 2 of the pioneer tsa300d4 speakers will need exactly 800W rms at 1 ohm, only if connected in parallel.

    It is recommended to use an amplifier with a higher output than needed for better sound quality and experience. Please see below.

  • Question: 10 August 2021
    Car: VW Transporter - <2004

    can i run 2x Focal SUBP25DB 10inch at the 500w 2ohms output of this amp.
    4ohm & 4ohm at parallel equalling 2ohm

    Answer: 
    Hi,

    If you are connecting 2 dual voice coil speakers at 4 ohms parallel, it will be cutting it close.
    The below amp should give you much better output:-
