Frequently bought together:



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


  • 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.

    It works great. temperature gauge doesn't seem to work. It was reading hot as soon as I plugged it in even though the amps not hot. We'll see what happens.

    Best bang for your buck.

    Probably one of if not the best amp you can buy for the money. Quality is unmatched and power output is no joke. Amp has no issue pushing the power it is rated for plus some. Clip light is an awesome addition too!

    Just plain awesome!

    From the beautiful anodized blue case to the excellent build quality this amplifier is amazing. Big power for the money, sounds fantastic. The bass knob is bad ass. If you're on the fence, buy this amp! You won't regret it. I'm getting the matching 4 channel next.
