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 :-)

    This amp is so good I'm going to get 3 more for my next setup

    So I originally bought a ds18 amp from y'all and it just got so hot in the Vegas summer, so I decided to just buy this to go with my jp34ab, and damn, gain isn't near clipping so I can have headroom, but damn does it still knock my sun visor back and forth. Next setup I will buy 3 more and have 2 pairs strapped powering some zv6's. I see why y'all have so many in stock, these are the shit. Like for real

    I am very happy with the jp23, i was originally looking at taramps but the bass knob sold me, I would have spent more money and went with the JP33 if it also had a wired bass knob, I dont like the idea of bt bass knob The JP23 seems to run cool while bumping for 40 minutes to an hour, it stays around 120 F at 1ohm

    Looks great has some flaws imo

    love the look and style. but does get hot, i got the big 3 done and large zero wiring to it. my car voltage will drop from idle 13.5 to around 12 volts anywhere in the 12s.. supposed to put out 2k watts at 12.6 i believe? maybe less? does't seem like the power is there.. i had a ct sounds 2000.1d amp at same voltage one big three as well. that to me in my situation put out more power. or seems to me like it does. also never had a over heating issues with ct sounds 2k. not entirely sure what issue could be. im taking steps and adding a volatage booster from singer on my alt.. i am upgrading my lead battery to agm, and also adding the 3000 series battery bank in trunk. maybe if it will hold in 14's to high 13s. it would be competitive with the ct sounds 2000.1d and hopefully not over heat after 1 song.. i did add a piece of wood with washers to lift amp off the carpet for it to breath from the bottom. but i also wont settle for a amp that has to run external fans on it, we aint talking a 5k or 10k amp here.. its 2k on paper. probably 1500 at most in my opinion with my person setup.. after doing some upgrade if it produces what it should i'll change my review.. but i love the look best looking amp imo. Down4sound. if you see this. i go to alot of car shows. help me out and get the power this thing says it will do. and i'll rep your shirts and stickers on my lexus vip built ls430.. any advice would be great too.. please don't take my experience as hate. love Down4sound..

    JP23 amplifier

    Overall a great amp. It has the power, controls, and looks. The only complaint is the brightness of the bass knob, at 5 am its blinding!

    Awesome amp

    Great amp for the money. Running this amp on two sundown SA 12s in the pro fab box. 250 amp alternator and the big 3. Sits at 14.4 volts and dont move. Pushes them sundowns to the limit. Planning on adding another 12 down the road. Awesome job JP!
