PowerBass 2XL-403 4" 3-ohm car speaker

SKU CH-E2SG-5B6NK

A 4-inch coaxial car speaker rated at 3 ohms with 50 watts RMS power handling per unit and a 68Hz to 20kHz frequency response

  • Speaker unit size4 in (10.2 cm)
  • Product type4 in (10.2 cm)
  • Handles 100 W RMS per pair for clean output
  • 3-ohm impedance draws more power from factory amplifiers
  • 68 Hz–20 kHz range covers full musical spectrum
  • 88 dB sensitivity produces loud sound with modest power
  • 2" mounting depth fits tight factory locations

PowerBass 4-inch coaxial speaker

The PowerBass 2XL-403 is a 4-inch full-range coaxial car speaker designed for drivers who want clearer sound from a factory speaker location. It uses a 1-inch silk dome tweeter and a non-woven wool paper cone to cover a wide frequency range. The butyl rubber surround and heavy motor structure are built for durability in automotive environments. A PBX custom mesh grill is included to protect the driver.

3-ohm nominal impedance

This speaker presents a 3-ohm nominal impedance, which is lower than the 4-ohm load most factory head units and aftermarket amplifiers expect. Wiring it to a standard 4-ohm stable amplifier will draw more current and can trigger protection circuits or overheat the amp. Verify that your amplifier or head unit is rated stable at 3 ohms per channel before installing these speakers.

Suited for 3-ohm systems needing 50 watts RMS

These speakers suit owners replacing 3-ohm factory speakers in compatible vehicles or builders with amplifiers specifically rated for 3-ohm loads who want 50 watts RMS per speaker. They are not for installations where the amplifier is only stable at 4 or 8 ohms, nor for systems requiring more than 200 watts peak power handling per pair. Buyers needing deeper bass below 68 Hz or higher sensitivity than 88 dB should consider other options.

Questions about this item

What does the 50-watt RMS figure mean when the speaker is installed in a car door?

It means each speaker can handle 50 watts of continuous power without damage, so match it to an amplifier rated around 50 watts RMS per channel at 3 ohms for clean output.

How does the 3-ohm impedance affect what amplifier I can use?

The 3-ohm nominal impedance draws more current than a 4-ohm load, so the amplifier must be stable at 3 ohms or lower; most modern car amps are, but check the amp's specifications.

Will the 2.2-inch mounting depth fit behind my factory door panel?

The speaker needs 2.2 inches of clear depth behind the mounting surface; measure your door cavity to confirm there is no obstruction from window mechanisms or wiring.
