JP 63 Amplifier: 6300W PLUS RMS MONOBLOCK Amplifier

We introduce the JP-63 , the 6300 WATT RMS (PLUS WAY more if you have a solid electrical) monoblock amplifier. It's like an 6k (6000 WATT) amplifier just with WAY more power. This 6000 watt amp is great for a serious basshead looking to bang some monterous , storm stomping bass out of their subwoofer.. REMEMBER, This isn't your typical 6000 WATT plus amplifier, we upgraded the input to 3 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 Clearwater Turquoise.


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.

    Great amp, tons of power

    Posted by Joshua Southard on Apr 21, 2023

    Amp works fantastic, by far the most power I've ever had. Only issue I'm having is I can't get the amp to turn off. Even with the remote wire unhooked it stays on.

    Best amp I’ve owned

    I’ve had Rockford, JL Audio and Memphis amps in last but this is a different type of breed when it comes to a amp. Absolute monster!

    Posted by Mark Cage on Mar 16, 2023

    I bought 4 Jp63's. This amp is beauty and the beast. Color is so nice I've been thinking of changing my van that color to match. Going on 8 Sundown X15's can't wait.

    Cool color..great sound...

    Posted by Steve S on Feb 10, 2023

    Bought this amp after having purchased a JP34ab and loving that one. Was using another brand 8k amp but it just didn't sound right. Hooked this one up, adjusted gain, and without any other changes it became apparent that this isn't just a 6k amplifier. Its cleaner sounding, plays noticeably louder, and looks better than the 8k I had. If you need 6k+ power you need this amp don't hesitate its well worth it.

    I’ve bought the JP63 amplifier from the online Down 4 Sound store and I was quite impressed with the discounts and incredible fast shipping. I strongly recommend buying if you haven’t already. No negative reviews here so far. I purchased the JP84 a week afterwards. I will definitely be buying again ✌
