Warzone WZ-E402 4" Coaxial Car Speakers

The Warzone WZ-E402 is a pair of 4-inch coaxial car speakers designed to replace compatible factory speakers in compact door, dashboard, or custom mounting locations. Each speaker combines a woofer and integrated tweeter in one assembly, helping simplify an upgrade where space is limited. It is intended for vehicles with suitable mounting dimensions and a compatible 4-ohm speaker circuit.

This pair is suited to listeners replacing worn factory speakers or building a compact full-range system without separate tweeter mounting. The coaxial layout places the 2-inch PEI dome tweeter over the woofer, allowing low, midrange, and high-frequency content to come from a single speaker location. Verify the vehicle's opening, mounting pattern, and available depth before purchase.

The WZ-E402 is rated at 400 watts maximum power and 200 watts RMS per pair. Its 4-ohm impedance supports use with compatible car-stereo or external-amplifier speaker outputs. An 88 dB woofer sensitivity rating and an 85 Hz to 20 kHz overall frequency response describe its intended full-range operating range.

A 1-inch woofer voice coil and 10-ounce ferrite magnet form the core of the woofer motor assembly. The integrated PEI dome tweeter is specified from 1,500 Hz to 20 kHz with 92 dB sensitivity. A 6 kHz crossover point is included to direct high-frequency content to the tweeter.

For system planning, the WZ-E402 works where a compact 4-inch replacement is needed and where bass below its stated response range can be handled by larger speakers or a subwoofer if desired. The pair includes protective grilles for installations that need exposed-speaker protection. Match power levels appropriately and use secure mounting hardware and wiring practices for the vehicle application.

Key Features

• 4-Inch Coaxial Design: Combines woofer and tweeter functions in one compact speaker assembly.
• 400W Maximum Pair Rating: Provides a stated maximum-power rating of 400 watts per pair.
• 200W RMS Per Pair: Supports system planning with a 200-watt RMS pair rating.
• PEI Dome Tweeter: The integrated 2-inch tweeter is designed for high-frequency reproduction.
• Ferrite Magnet Motor: A 10-ounce ferrite magnet supports the woofer assembly.
• Compact Fitment Dimensions: A 3.74-inch cutout and 1.66-inch depth aid installation planning.

Design & Installation

The WZ-E402 uses a coaxial architecture with a 4-inch woofer, centrally integrated 2-inch PEI dome tweeter, 1-inch voice coil, and 10-ounce ferrite magnet. This arrangement keeps the full-range speaker package compact while retaining dedicated high-frequency reproduction. Protective grilles are included with the pair.

Each speaker requires a 3.74-inch cutout and 1.66 inches of mounting depth, with a stated overall diameter of 4.02 inches and overall height of 2.18 inches. Confirm clearance behind the mounting surface, factory mounting-hole alignment, and connector or wiring requirements before installation. Use the pair with compatible 4-ohm car-audio amplification and verify power matching against the stated RMS rating.
