Prevents magnetic flux from radiating from the subwoofer's coil, resulting in reduced noise and enhanced sound quality.
PMLCAP's (Polymer Multi-Layer Capacitors) are utilized in the LC filter circuits to decrease distortion, ensuring clear detail for a truer to life sound.
Gauge-style terminals lock wire
into position with set screw for secure installation.
All terminals and connections are on one side for easier installation and a cleaner look.
Speaker Level Input Harness is included to connect to speaker wires from factory installed receivers.
The wired remote level control allows you to easily adjust the subwoofer volume.
