I understand that this amp requires specific significant charging upgrades. I have already made these upgrades or will do so before attempting to install and operate this amplifier.

I am responsible for damage to the amp caused by an inadequate electrical charging system.

SKU: S1-2250.1 Categories: , Tags: , ,


Disclaimer: This amplifier will require an additional charging system to run efficiently. It will run without the additional charging system but you run the risk of damaging the amplifier and/or not getting the optimum power out of it. The additional charging system includes the Big 3 upgrade, a high output alternator, as well as adding an AGM or Lithium car audio battery. All of our amplifiers are age tested for an hour before going into stock.

Following the massive footsteps of our most popular mono amp, the S1-2250.1 monoblock car amp has even more heat sinking and improved circuitry than its predecessor. The advanced heat reduction and a heavy-duty printed circuit board helps to keep its overall operating temperature low, to prevent internal damage.

High-quality class D amp design keeps your amplifier cool, guarantees low rates of total harmonic distortion, and prevents its high output performance from damaging your car. To enjoy the full power this amplifier offers, you will need an upgraded electrical charging system.

The S1-2250.1 drives an immense 2800 watt load at 1 ohm on 16 volts and 2300 watts on 14.4 volts at one ohm. This monoblock amp is ready to drive your choice of HDS2.2’s, HDS3.2’s, or HDX3 Subwoofers in the 1200 Watts RMS and 1500 Watts RMS Power Bands.

Strappable for 4600 watts at 2 ohms, this budget King mono block amp is capable of and ready for Sound Pressure Level competitions and anything else your car stereo can throw its way. 

The S1-2250.1’s screw terminals accommodate up to 1/0 AWG power wire and up to 10 gauge speaker wire. Find everything you need to install this amplifier with our Zero Gauge Amp Kit. 

To secure a long life for your new amplifier, a remote gain control knob is included with your S1-2250.1. The LED indicator alerts you straight away to the presence of clipping signals that can quickly burn or separate your subwoofer voice coils, as well as create bubbles in your former.

We include the remote gain knob to help you avoid costly and needless damage to your gear. Utilize this in tandem with the VM-1 to keep a close eye on your voltage with 60 voltage checks per second for near real-time precision readings.

You’ll love your new S1-2250.1 Mono Amp- From the hard rhythmic hits of a bass drop to the subdued thump of a soft kick, you’ll be able to hear and feel all the detail, impact and precision in your sound system’s low end!

    I’ve personally been running SQ amps for years now and they always perform flawlessly. Recently installed this amp for a customer of mine, in his Camaro. It’s pushing 2-10” subs (1000rms rated ea.) He kept the factory head unit and speakers and I just added the back end. *Enclosure and an l.o.c. WOW!!!!!! Pressure inside this small cabin area is unreal. Amp is set just passed 1/4. Stock alt and battery, with VERY minimal light dimming. Putting in work!!!!! When you roll the bass knob up to 1/2…..it’ll run ya up outta there..😂😂😂 Amazing amp, you will not be disappointed 💯.

    Can’t beat the price for what this amp puts out. I’ve ran 2 MTX TS85 12’s on it for the past 3 years. The amp broke sent it in for repair for a great price and received it back in a week. It ended up killing the mtx subs. I didn’t think it was possible with this amp but it’s a beast.

    This amp will push 2 Hds3s like you wouldn’t believe. Just have your electrical on point and let the amp do the rest

    This amp is a beast and you cant beat it for the price. I’ve ran with alot of different companies over the years (Im 48) but once I got my first SQ set up, I’ve stayed with them since. About 4-5 years I’ve been running their equipment. Affordable power and performance. I have 2 of these and one of the last model S12250 and as long as you have you’re electrical up to par, you will not be disappointed with this amp. This amp will do over certified rated power. Get 2 and strap em for over 4600 watts at 2 ohms. 1 ohm each amp. This new model definitely runs cooler than the old one, but I never had an issue with the old one overheating as long as I remembered to turn the fans on. I highly recommend SoundQubed all day!! Keep up the great work guys.

    Love soundqubed man have this amp hooked up to 2 hds3.2 15s in my 2015 genesis at 1 ohm and can definitely feel this bass hittin extremely hard for 200$ subs. In this full size sedan
    takes some power to actually feel the subs in these big cars but extremely clear sound quality highly recommend.
