With a sensitivity of 103 dB, these tweeters effortlessly cut through noise. Designed for easy installation, they allow you to upgrade your sound system quickly and effectively.
Powering this setup is the G3600.4D Despite its compact size, this amplifier provides massive power outputs—4 x 300W RMS at 4 ohms, 4 x 420W RMS at 2 ohms, and 2 x 740W RMS at a 4-ohm bridge—allowing for customizable sound thanks to integrated low pass and high pass filters.
Completing this package is the OFCKIT4, including everything you need for a flawless installation: power, ground, and remote OFC wiring, a Mini ANL Fuse Holder with a 150 Amp Fuse, along with various cables like a precision-engineered 17-foot red/black twisted RCA cable and turn-on cable.
