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. 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.
