JP 23 AMP: 2300W RMS MONOBLOCK Amplifier V1.5

VERSION: 1.5 features a thick PLEXI BackPlate; we also UPGRADED a resistor to make the amplifiers even more unbeatable. ⚡⚡

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 fans turn on at 120 degrees or when the amplifier detects electrical stress and excessive heat during playtime.


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.

Amplifier Dyno Sheets: 

Amplifier Dyno Numbers are an Idea of power you'll be getting from the amplifier. The JP23 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 :-)

    JP23 Amp

    I am amazed at the quality of this amp. It delivers good clean power and makes my sub bang as hard as the two I used to have! I definitely recommend this amp for anyone that wants great power from a trusted name!

    JP absolutely killed it with this amp! I was expecting a mediocre budget amp. But this thing puts out the power! The bass knob is my favorite part so I don’t have to have a separate volt meter and I always know if I’m clipping or not. D4S FTW!

    JP23 V1.5

    Posted by Robert Edwards on Oct 30th 2021

    I haven't got it installed yet but plan to tomorrow when my DC level 4 12-in sub comes. It should be perfect to run that at 2 ohms and bang pretty hard. But the amp is beautiful and built very well. I can't wait to hear the sound of it. I've got a Down4sound JP8⁴ running my mids and it does the job very well. So I can imagine the JP23 pushing some sound!
