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 :-)

    amazing product

    Posted by Daniel Bennett on Aug 15, 2023

    This is our 2nd jp23 and we have it strapped, pushing 2 CAS 12's. With it being strapped it's putting out the same voltages as my salt amp. Definitely a great product from JP and his team.

    Posted by Shane Peeler on Jul 13, 2023

    Got my JP 23 worked good had problems with it as well got a blowed cap in the amp now the amp does not work correctly but you better get an extra extended warranty because mine ran out the week after is when the cap and now they will not do nothing about it they told me they send it in for repairs but it will be around $160 to $200 I might as well buy a new amp so just fair warning I thought this was a great company until this happened get your extended warranty ASAP

    Broken Amp

    Posted by Christopher Bulit on May 27, 2023

    I have been struggling to get in contact with customer support, I sent an email a while ago and was responded to once and then your team was not heard from again. Upon turning my truck on last night after work the amp itself was in protection mode and has not come out since, I have unplugged and let it rest and have lowered the gain and volume on the bass knob to a minimum and nothing, I was wondering what the next step should be from here.

    This thing is great! Clean sound and stays cool. I’ve had it for about 6 months now and I haven’t seen it get above 105 degrees. When it got to 105 I had been pushing it for around 20-30 minutes. I have it paired with a single sundown audio x12 v2.

    Amazing power

    Posted by Christopher "Kit" Bolton on Apr 25, 2023

    This amp puts out 3400watts at 1ohm. Ran 4 — 15” subs on it at 1ohm. Sounded amazing. I love the volt/volume control.
