Thread boosted bass throughout your auto with the Alpine PWE-S8 subwoofer. This compact 8-inch unit, boasting 120W RMS power, delivers amplified sound perfect for any car needing a bass enhancement. It's an ideal choice for smaller vehicles where space is a premium, serving as a great addition to an existing audio system or the starting point for a complete overhaul. The PWE-S8 features a shallow mount design, with its deepest point measuring just 3 inches. Its overall dimensions are 13.5 inches wide by 9 inches tall, making it application-ready for placement under or behind seats in pickup trucks, within sedan trunks, or in SUV hatches. The construction utilizes cast metal for enhanced durability and performance, protecting against potential bumps and bruises. Connectivity and control are made accessible via a side panel that provides access to speaker and RCA inputs, along with controls for Phase, Gain, Low Pass Crossover, and a Remote Sub Level knob. The frequency response ranges from 25Hz to 152Hz, with a low-pass crossover adjustable from 50Hz to 150Hz, allowing for precise tuning of your low-end frequencies. It comes with a 13-foot remote bass level knob, input harness, mounting brackets, and an owner's manual.
