JP 83 Amplifier: 8300W PLUS RMS MONOBLOCK Amplifier

We're excited to introduce the new JP-83! This is a 8300+ watt RMS (plus way more if your electrical is solid) monoblock amplifier will make any subwoofer pounds its lungs out with bass like never before. The increased power demand means this unit needs a big 3 Alt+ Reserve battery installed. Connection is 3 zero gauge power and ground wire inputs. To keep the this monster thermal stable, we upgraded the weight of the heat sink and added active hi-flow internal fans. You'll also notice that this 8000 watt monster the TRUE tiffany RCA connections, not no off the shelf junk, because a great sound, starts with great connections. This amplifier is strappable (linkable) so you can really harness the power. The D4S JP83 amplifier means the business for anyone looking for an 8000 watt+ monoblock amplifier!


THIS MEANS YOU NEED A BIG 3, UPGRADED ALT, AND RESERVE BATTERY(s) to support this amplifier and any others you may have in your setup. If you do not have the proper electrical before installing this amplifier, you will not have a warranty.

    Awesome Amp

    Posted by John F on Dec 15, 2022

    AMP performs like a champ... needs power... D4S has carefully developed their brand to be quality... whatever JP is doing with these manufacturers is yielding dividends... the D4S DNA in each of their products provide a best in class per price point that is undeniable... hope they never change their commitment to providing value and quality to their customers... make less profit per item but dominate market share... that's how you build an empire that will last... I unreservedly recommend all things D4S...

    Build quality

    Posted by Clint on Nov 24, 2022

    Hooked up for 3 weeks now. Amp is very powerful with 15 volts, solid sturdy knobs, and the heavy duty heatsink is quality u can feel and see. Bluetooth knob is cool. Other than a little board noise upon startup this is a very good sounding amp for the price. Might just get another!

    Posted by David Raines on Sep 12, 2022

    I bought the first one back in June at slamology and it is doing great, I ordered 2 more and am currently running 2 of the 3 and they are doing really well,sound quality is great out of these amps and they are very powerful. Probably the best Korean board I have owned yet.

    I call this amp The Money Shot or Green Monster!!! Total Bad ass amp

    Posted by William Shoesmith on Aug 16, 2022

    I've been into car audio for almost 30 years and haven't seen this kinda quality since I was 20. US Amps ,Lanzar,Earthquake to name a few.of the brutally built amps back then. Build quality if phenomenal and this thing bangs. Crystal clear earth shaking bass. Very very happy with my purchase. I was hesitant till I saw the Williston Labs Amp Dyno and was amazed. Was gonna do a Salt or Xfire and glad I took the chance on this bad boy. And im only running it at 2ohms. Finally a true contender that will last and I can grow into. My 2 DC Audi XL SPL 12s are really beating now. Thanks JP and keep it up bro. Maybe some subs next?

    The jp83 monster

    Posted by David on Aug 09, 2022

    I have had this amp hooked up now for about a week.It is very strong and power hungry at .5 ohm. Only thing I have noticed with the amp is you have to almost have the subsonic filter on 10 or right at 10 to really get any good bass out of it, not sure what's going on with that but I planned on getting 4 total and will still do so, overall good amp, the bass knob takes some time getting used to kind of a pain to have to turn it up ten rotation to get to full max e every time you turn the car on, but besides that I like it how is digital and temp sensor is great.

    Nearly perfect...

    Posted by Tony Giamei on Aug 06, 2022

    The one thing this amp is missing is hardware included to simplify mounting it to show off the see through bottom. It also may be easier to mount it if there was a slight change in the design of where you connect things to the amp. Other than that, it doesn't get better than this!
