Features

  • Powerful Monoblock Bass Amplifier: Puts out nearly 1500W RMS @ 1 ohm with charging system upgrades (16V). Dial in the perfect tuning for your sub stage with the S1-1250s subsonic and low-pass filtering. To take things up a notch, you can strap two S1-1250s for higher combined power output. If you want to jump into car audio with both feet, this amp will push a pair of HDS2.2 Subwoofers with power to spare.
  • Next Level Power for Everyday Stereo Systems: The S1-1250 is a Class D subwoofer amp for intermediate power levels that may push the limits of a factory alternator/battery. This is an audio amplifier for cars with higher output stock alternators, or upgraded electrical systems. Know your charging specs before you buy any amp. You generally need 100 amp hours per 1000W. So, for a 2000W class D monoblock amplifier, you would need a 200 amp alternator.
  • Stays Cool as a Cucumber: Aluminum heatsink and improved circuitry make for excellent cooling. This efficient class D monoblock amplifier design keeps more power flowing to your system instead of turning into heat, so you can play louder for longer.
  • Easy Install, even for Dummies: Set screw terminals connect easily to your power and speaker wire. Surface-mount feet make securely mounting the S1-1250 a cinch. To get everything you need for installation, check out the SoundQubed Four Gauge amp kit. Wiring configuration and ohm load allow output from 530 to 1490 Watts RMS.

  • Great product, True wattage, best bang for your buck.
Size: 900 Watt
This amp was suggested to me by a friend in the the competition side of bass. I couldnt be happier. Talk about watts for the money i give it hell and it keeps taking it. I had to do the big 3 wiring for the battery/ alternator to keep power to this baby. The clipping indicator allows you to properly adjust the amp to keep you from burning up any components unknowingly. With this you know if you are doing damage to you setup. ... show more

  • Underrated
Size: 900 Watt
This thing does well over rated power with proper electrical. I even ran it on .5 ohm for 2 hours straight. It did heat up a little, but nothing out of the ordinary. It was cooler than the skar lpv2 750.1(could cook an egg on 1 ohm) it replaced. Final goal is for this to power an 8 inch tezla audio 1.5k at 2 ohms. ... show more

  • Do...NOT...wire below 1 ohm.
Size: 900 Watt
The amp is as advertised. I have it wired too 1 ohm in a daily driver and it works flawlessly. Doesnt get real hot. No thump on turn on. And the bass knob with clip light is such a valuable tool you just cannot go wrong with the S1 series. Highly recommend. Forget the price. Forget stickers. This amplifier does its job well. ... show more
