This comprehensive audio package, the Chevy Blazer 98-05 Harmony Single 12" Loaded Sub Box Enclosure with CXA400.1 Amp, is specifically designed to deliver enhanced bass and sound quality for your vehicle. The core of the system is the Harmony Audio HA-RS12 12" subwoofer, housed in a robust 5/8" MDF wood vented enclosure. This enclosure is engineered with a custom-tuned port (33Hz) for optimal low-frequency response, handling up to 600 watts peak and 300 watts RMS. The subwoofer's sensitivity is rated at 88.2dB, with a broad frequency response from 25Hz to 300Hz. Powering the subwoofer is the Kicker 46CXA4001 Class D mono amplifier. This efficient amplifier delivers 300 watts RMS to the 2-ohm subwoofer and is stable down to 1 ohm, producing 400 watts RMS. It features a 3-second turn-on/off delay, variable crossovers, a KickEQ bass boost, and a subsonic filter for system protection. The FIT+ technology ensures compatibility with most factory radios. To ensure a complete and professional installation, the package includes a Harmony Audio HA-AK8 complete 8-gauge amplifier installation kit, featuring all necessary power, ground, remote, and speaker wires, along with a Mini ANL fuse holder and 80 Amp fuse.
