JP 43 Amplifier: 4300W PLUS RMS MONOBLOCK Amplifier

We introduce the JP-43 , the 4300 WATT RMS (PLUS WAY more if you have a solid electrical) monoblock amplifier. It's like an 4k (4000 WATT) amplifier just with WAY more power. This 4000 watt amp is great for a serious basshead looking to bang some monterous , storm stomping bass out of their subwoofer.. REMEMBER, This isnt your typical 4000 WATT plus amplifier, we upgraded the input to 2 power and grounds, added the best RCA's true tiffany, the internal fan now stays on as soon as you turn on the amplifier to keep it cooler longer. The color is Cream Orange.


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.

    Real Deal..... NO Joke

    Absolutely love it. From the box opening and checking out the the mounting and witing it on my rack. I had to admire it. Then when you actually turn it on and hear the raw output through my 4 SA 8s, I realized it was worth every penny. You get what you pay for and much more with this masterpiece. TEN....F'in TEN!!

    By far my favorite amp of all time. I bought it to replace my last favorite amp (JP23) so I can get louder. It far exceeded that goal. This amp is amazing! I have it pushing 2 Ampere Audio 10's. This amp is absolutely beautiful , makes tons of power, I couldn't be happier. I highly recommend this amp. Thanks for taking amps to the next level with the colors, power, bluetooth bass knobs and super high quality parts.
