JP 23 AMP: 2300W RMS MONOBLOCK Amplifier

The JP23 might be the most overdone, 2300 watt amplifier ever to hit the market. R&D in Las Vegas, NV & Dunnellon FL with the brightest minds historically in-car audio dating back to the late '90s thru the 2000s AND TODAY. We took the old school approach of building a quality amplifier, heavy heatsink, and quality hardware. Then we applied what our basshead clientele wants with technology, durability, and features for both competition and daily use.  

Inside the JP23 is a fan cooling the output side; and Bass Knob with voltage and temperature meter.

The JP23 was born into production; this is Down4sound's 1st amplifier, and each amplifier is serialized for 1st, 2nd, and 3rd editions.


The warranty doesn't mean we cover it if you hook it up wrong or launch it out a potato launcher or someone dropped it or if your ex comes by and steals it. It also doesn't cover you feeding it the wrong voltage distorting it malfunction, or you submarining it in your vehicle. This Version IS NOT Marine Grade.

There is an Optional half ohm warranty, in the options above, which protects you for .5 ohm hook up for 1 year.

Amplifier Dyno Sheets: 

Amplifier Dyno Numbers are an Idea of power you'll be getting from the amplifier. The JP23 does above rated above power the two testers; that's a plus; most music is played at about clipping, so the uncertified test numbers are significant as bass tuned setups today are played to about clipping anyways. We highly recommend 14.4v - 14.7 volts to get the most from this amplifier; 14.4 is okay, but if you're trying to JAM 14.8v. Install the JP23 and Hear the music :-)

    This product definitely does the job it is Intended for and is definitely underrated I do wish the efficiency was better but it is definitely worth the money planning on getting another one when I get my high output alternator and better subs
