Fit and use
Shallow woofers like the P3SD4-12 are intended for spaces where traditional deeper subwoofers cannot be used. The dual 4‑ohm voice coils allow multiple wiring options to match amplifier/channel requirements and system goals. Performance will depend on enclosure design, available amplifier power, and vehicle acoustics.
What to know
Rated for 400 Watts RMS—match amplifier power and impedance to the subwoofer and wiring configuration. Actual bass output and response depend on enclosure type, installation quality, and vehicle acoustics. This model is designed to provide usable low-frequency output where depth is constrained.

Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application. Shallow woofers are specifically designed for spaces where a traditional woofer cannot be used.
