What this product is

These are 4-inch coaxial speakers rated at 40 watts RMS and 120 watts maximum power. They are sold as a pair with a 2-ohm impedance. The grey cones use injection-moulded polypropylene and carbon fibre. A butyl rubber surround helps control cone movement.

The specification that decides fit

The shallow mounting depth and OEM drop-in replacement design determine whether these speakers fit your vehicle’s factory locations. Check the available depth behind the panel before ordering. The 2-ohm load must match the amplifier or head unit specifications.

Installation notes and common issues

The shallow profile eases installation in tight door cavities. Wiring to a 2-ohm stable amplifier is straightforward. Common issues include mismatched impedance causing amplifier shutdown and factory grilles not clearing the tweeter housing. Verify clearance and wiring polarity during fitting.

Questions about this item

How loud will 40 W RMS actually sound in a car door?

40 W RMS is the continuous power the OE-402 can handle without distortion; paired with a matching amplifier it delivers clear mid-bass and vocal detail at highway volume.

What does the 2-ohm impedance mean for my factory head unit?

The 2-ohm load draws more current than standard 4-ohm speakers, so the OE-402 needs an amplifier or head unit rated for 2-ohm operation to avoid overheating.

Will the shallow mounting depth fit behind my door panel?

The OE-402 uses a shallow-mount chassis designed as an OEM drop-in replacement, allowing it to sit behind most factory door panels without spacer rings.
