Warzone WZ-E402 4" Coaxial Car Speaker Pair

The Warzone WZ-E402 is a pair of 4-inch coaxial car speakers made for replacing worn factory speakers in compatible door or dashboard locations. Each speaker combines a woofer and integrated tweeter in one compact assembly, helping retain full-range sound where installation space is limited. The pair is designed for 4-ohm mobile-audio systems.

These speakers suit drivers building a simple factory-speaker replacement or adding sound to a compact custom installation. Their 4-inch format is intended for vehicles with appropriately sized factory openings, though vehicle-specific fitment should always be checked before purchase. Protective grilles are included for installations where the speaker face needs coverage.

The WZ-E402 pair is rated at 200 watts RMS and 400 watts maximum power per pair. An 85 Hz to 20 kHz frequency response supports midrange, vocal, and high-frequency reproduction from a single speaker location. With 88 dB woofer sensitivity, the design is intended for everyday listening systems with suitable amplification or head-unit power.

Each coaxial speaker uses a 4-inch woofer with a 1-inch voice coil and 10-ounce ferrite magnet. A 2-inch PEI dome tweeter is integrated above the woofer for high-frequency output. The tweeter is specified from 1,500 Hz to 20 kHz, with a 6 kHz crossover helping direct upper-frequency content to the tweeter.

For an upgrade path, the WZ-E402 can be used as a compact pair in compatible front, rear, door, or dashboard speaker positions. Its 4-ohm impedance makes it appropriate for matching with compatible car-audio amplification. Confirm mounting diameter, cutout size, mounting depth, wiring polarity, and available clearance before installation.

Key Features

• 4-Inch Coaxial Design: Combines woofer and tweeter in one compact speaker assembly.
• 200W RMS Per Pair: Supports appropriately matched car-audio power for everyday listening.
• 4-Ohm Impedance: Works with compatible 4-ohm car-audio speaker channels.
• PEI Dome Tweeter: Provides dedicated high-frequency reproduction in each speaker.
• Ferrite Magnet Motor: A 10-ounce ferrite magnet supports woofer operation.
• Included Protective Grilles: Adds coverage for suitable exposed-mount installations.

Design & Installation

The WZ-E402 uses a coaxial layout that places its 2-inch PEI dome tweeter within the 4-inch woofer assembly. Its woofer employs a 1-inch voice coil and 10-ounce ferrite magnet. This design keeps the speaker package compact while providing separate woofer and tweeter elements.

Each speaker requires a 3.74-inch cutout and 1.66 inches of mounting depth, with a 4.02-inch overall diameter and 2.18-inch overall height. Verify the vehicle opening, mounting pattern, panel clearance, and window or dash clearance before installation. Use compatible wiring and ensure the amplifier or receiver is suitable for 4-ohm speakers.
