Key Features

1 Ohm Stable 5000W Monoblock Subwoofer Amplifier **FREE AMPLIFIER WIRING KIT** - In Phase Car Audio IPA5001D

The New InPhase IPA range of amplifiers from InPhase is possibly one of the best car amplifiers available today. 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 1 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.

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.

I love this amp, it looks great and WOW it is powerful. My car has never produced so much bass. I am running this on my DB Audio Trex 15, all my friends think I have 2 subs when I only have one. Even my eyes rattle!
