The Jensen XA2100 amplifier makes it simple to turbocharge your sound system with features like high- and low-pass variable crossovers, top-mounted controls, and gold-plated inputs and outputs. A built-in 6 dB bass boost at 45 Hz lets you dial in more bottom-end impact.

Planning on a multi-amp system? Preamp outputs on these XA Series amps make it easy to install multiple amplifiers. Speaker-level inputs means these amps are easy to hook up to any radio, whether or not it has preamp outputs.

While supplies last, get 2 FREE Advent 10" AM-10 4-ohm component subwoofers when you order the XA2100! We'll add the subs automatically to your order, and you'll see them reflected in your order confirmation e-mail.
