JP 8 AMP: 800W PLUS RMS MONOBLOCK Amplifier

The JP8 might be the most overdone, 800 watt amplifier ever to hit the market. R&D in Las Vegas, NV & Dunnellon FL. The Heatsink carries over from the JP23. The blue color takes from the OG days of Down4Sound and Car Audio, we call it OLD SKOOL BLUE.  

Inside the JP8 is a fan cooling the output side; now it has plexi black plate, and Bass Knob with voltage and temperature meter.

  • Internal Fan turns on at 120 degrees F

OUR STANDARD 1 YEAR MANUFACTURE DEFECTS | JUST LIKE ANY MANUFACTURE.

  • 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.

There is an Optional half ohm warranty, in the options above, which protects you for .5 ohm hook up for 1 year.

    JP8

    Posted by Dustin Moore on Nov 15th 2021

    This is a beautiful & powerful amplifier. It looks to be built with care, all the way down to the small SMT components. I have this amp paired with an 18” Skar SDR and it delivers! I can’t wait for more JP products. Keep up the good work!

    The D4S JP8 looks good and has lots of clean power. Nice amp with good features for a great price. Also not too hard on my oem charging system!
