JP 33 Amplifier: 3300W PLUS RMS MONOBLOCK Amplifier

We introduce the JP-33 , the 3300 WATT RMS (PLUS WAY more if you have a solid electrical) monoblock amplifier. It's like an 3k (3000 WATT) amplifier just with WAY more power. This 3000 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 3000 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 Battleship Grey.


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.

    Don’t buy just for bass remote features

    Posted by Claymon Taylor on Mar 23, 2023

    I had my JP33 for hooked up for less than a week before the Bluetooth knob stopped connecting to the amp. I would’ve had to mail the amp back for who knows how long to fix it. It’s best not to use it anyway bc it reset when you cut the car off and doesn’t turn on automatically. I thought my subs were gonna blow first time I got back into the car without knowing it would be at max output. Now as for the amp itself, powerhouse! I’m running 2x Sundown U D1 @ .5 and zero gain. Still rattles the hell outta my hatchback

    This amp is Beautiful and it's a Monster. It's hooked up to 2 12's right now, and it's killing them. I ordered a Incriminator Audio 21 inch sub to put it on. I'll provide another review after I receive the sub

    Running this on a SUNDOWN ZV6 12” at 2 OHM and it’s just pounds. Sound quality is top notch as well. Works amazing!

    Solid Amp!

    Posted by Greg on Jan 04, 2023

    Ok so I haven’t used this amp yet but it’s a major piece of my upcoming build alteration. I’m currently waiting for my Excessive Amperage alternator and big 3 upgrade and my JP77 amp. I’m going to use these in my SQ/SPL build. I’m planning in running my 6 front and rear doors and two 8in subs off my JP77 and two 12’s off my JP33. Of course also utilizing my DSP. The amp is built very good and I have no doubt it’s going to be a beast! Top quality for sure! Fast shipping and great customer service and support!

    Very nice

    Posted by Shane Graves on Aug 07, 2022

    Love the amps so far very clean bass. Only have 1 hooked up atm, 0guage ofc runs, 2 xs d3400, 250a alternator big. 2 sundown x15 in 2/1 4th order still drags my volts down to 11.8 so still need to get another battery and upgrade mechman 320 then hopefully it'll be enough to hook the other one up. Loving the bass knob.
