Key Features

2 Ohm Stable 1200 Watts Digital 4 Channel Amplifier **FREE AMPLIFIER WIRING KIT** - In Phase Car Audio IPA8704D

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

Customer reviews

Sound is high quality
Vik on 11/11/2021 5 star rating

I haved used In Phase amps for many years but never teh digital range. Not been a fan of class D digital car audio but with limited space in my car I decided to buy the In Phase Amp. I am very pleased with the sound, sound more like class AB then class D. Great sonics, bass reproduction is very tight and clear vocals to dream off!

POWER
Josh Gadden on 27/11/2020 5 star rating

The Power really blows me away with this Amp, I have a Kenwood amp that i have replaced and both are teh same power but the In Phase just sound So much louder! I dont know why? it also sounds so much clearer, the bass is very tight and drops low. WICKED Amp
