The Rockville QB10SPA is a single 10-inch subwoofer already mounted in a slot-ported MDF box with a built-in Class D monoblock amplifier. It takes speaker-level or RCA inputs, so it can be added to a factory stereo without a separate amp, and a remote bass knob lets you trim output from the driver's seat. The shallow 5.7-inch-deep box is sized for tight spaces like truck cabs and hatchbacks. It is a budget all-in-one bass solution; separate sub, box and amp setups offer more headroom and tuning, but need more wiring and space.
