InPhase 2000 Watts RMS Monoblock amplifier - In Phase Car Audio IPA2001D

InPhase IPA2001D

InPhase amplifiers are made to rock your world. With great muscle also comes refinement. Advanced features such as bass boost, fully variable zero to 60Hz subsonic filters and crossover networks with different frequency bands for highpass and lowpass, you will always have full control. Connectivity is excellent with high level as well as RCA inputs and a pass through RCA output to feed more amps, without needing multiple runs of RCA cables.
With 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. All the amps may be bridged for even more power into one channel.
Four and two channel designs, all with potent MOSFET power supplies, cover every need from single-amp whole system solutions, all the way to pavement-shaking power mania. There is always a high quality InPhase amplifier (or two) that’s just perfect for your hunger for power.
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.

The IPA range of car amplifiers gives you the true RMS power to power your system. Some of the amazing features of the new Inphase IPA range of amplifiers have a Subsonic filter so you can adjust your amplifier to deliver more power to the desire frequency range, which mean more power to your speaker. Line in and line out so you can run as many InPhase amplifiers as you want one a single RCA cable. Dual layer circuit boards for improved sound quality and low resistance from internal parts give you a smaller and yet more powerful amplifier.

    Hi i bought 2 inphase subwoofers 12" 3000w with 1000W RMS
    Also i bought from you a Inphase 2001D Amplifier.

    I would like to know what capacitor do i need for my setup to run easy ? Thanks


    ideally for every 1000w we would recommend a 1 farad cap so for yours we would recommend a minimum of a 2 farad ideally more if possible

    JW2D Power capacitor 2.4 Farad High performance Digital voltage displace
