InPhase IPA1601
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.

My amp gave up and I was unsure as to what one to buy. Gave these guys a call, they were really helpful and directed me to this amp, which I bought. The sound is really clear, it is much more powerful and honestly it sounds great. Definitely recommend this amp and Car Audio Centre

Gareth on 13/02/2012 5 star rating

I've had this amp for a few years now and am bored at work so thought I'd do a quick review of it:) Sounds great-in that it just makes music louder, I can't perceve any difference in tonality brought in by the amp. Used on subs of comps this has plenty of power, finesse and headroom. Build-like a brick you know what, it's been in 5 cars over the last few years, spent a while in the garage and generally not been treated too well-some scuffs on the top of it, but otherwise still firing on all cylinders Reliability-never let me down-wish I could say the same for the 5 POS cars I've owned in the time I've owned this!

    Car: VW Beetle - 1998>

    My car is a 1973 Beetle.
    What size in line fuse do I need on the power supply for the IPA 1601 amp? There's nothing I can find in the documentation.



    A good quality 80a glass fuse should be ok for it
