Key Features

1 Ohm Stable 7000W Monoblock Subwoofer Amplifier - In Phase IPA7001D

Keep things controlled – helped by forced air cooling on the real bass monsters.


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. This design enhances the flexibility to connect multiple subwoofers to a system.

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.

Power Supply Important Info

Whilst this amp has standard connectors and similar functions to other mono amps, but the power requirements are much different. The IPA7001D will require a heavy duty power supply, preferably a second amplifier. This amplifier is not for rookie installations or for rookies to install. An amplifier's job is to provide enough power to move the speaker cone (with a power hungry speaker, they are harder to move, hence the bigger power output), if that power going to the amp drops or is intermittent, it could cause the amp to clip the subwoofer!

Wow got this running 2 x 12 trex and it bumps haha Now running 4 x12 at 1 ohm sounds amazing P.s this amp is huge

Alexey on 31/08/2021 5 star rating

I have had many amps over the years on my trusted Rockford woofers. I needed an amp which delivered power and was musical. My main issue was the amp had to be powerful and stable at 1 ohm. My last amp died and I decided to give this In Phase a go as it is excellent value for money. Is it good? HECK YES. I would say this amp is a good as my ROckford DSM 200 from back in the day. Love this amp, had it now for 6 weeks and it just sounds better and better. I am very happy.

    Car: Audi TT - 2006> (8J)

    Hi, with this amp would I need a car battery upgrade? I have an Audi TT 2020 model and it's currently running two IPA2001d amps on two 15" DB Audi xtint but I'd like to upgrade to the single amp

    A battery upgrade always helsp any system but ideally a Independent is best for the system with a power cap, or just start with a Power Cap
