Without the “Big 3”upgrade and an added AGM or lithium car audio battery, you will damage the amplifier. These upgrades enable your vehicle’s charging system to generate and store enough power to power the amp and other vehicle features. Stock electrical charging systems cannot keep up with the power needs of the amp, which can very quickly damage the S1-2250.1 amplifier’s power supply. This is not a manufacturer defect. You will be responsible for repair and shipping costs according to our warranty and return policy.

SoundQubed S1 Series amplifiers are high efficiency, high output devices, with adjustable subsonic and low pass filtering controls to perfectly tune your subwoofer stage. The S1-2250.1 monoblock amplifier is also strappable for systems with greater power output needs. We strongly recommend upgrading from a stock electrical charging system to avoid damaging this amplifier.

The S1-2250.1 is a high efficiency, single-channel, class D amplifier. It is with the same power specifications of its predecessor. The amp has more heat sinking and improved circuitry to lower its overall operating temperature. Thermal and speaker short protection, as well as a heavy-duty printed circuit board protect against circuit damage.

Set screw terminals accommodate up to 1/0 AWG power wire, and up to 10 gauge speaker wire. Get everything you need to install this amplifier with our Zero Gauge Amp Kit.

Like all SoundQubed amps, we include a remote gain control knob with the S1-2250.1. The LED indicator alerts you immediately to clipping signals that can quickly burn or separate subwoofer voice coils, as well as create bubbles in your former. We include the remote gain control to help you avoid costly, unnecessary damage to your gear!
