Earthquake Sound FF6.5 Black Ash 6.5-inch 150 Watt Powered Subwoofer

SKU CH-Z451-MR4MN

A compact 6.5-inch powered subwoofer delivering 150 watts of bass for car audio systems

  • 150 watts of built-in amplification for strong bass
  • 5-inch driver fits tight enclosures
  • Black ash finish matches factory interiors
  • Powered design removes the need for a separate amp

Compact Powered Subwoofer for Space-Limited Installs

The Earthquake Sound FF6.5 Black Ash is a 6.5-inch powered subwoofer built for vehicle cabins where enclosure volume is tight. Its integrated amplifier delivers 150 Watt output without the need for a separate amp rack, making it a self-contained bass upgrade for factory or aftermarket head units.

6.5-Inch Driver with 150 Watt Built-In Amplifier

The single specification that decides fit is the 6.5-inch driver diameter paired with 150 Watt of onboard power, which determines whether the unit fits your available mounting depth and meets your output target. Buyers needing deeper low-frequency extension or higher SPL for larger cabins will find this driver size and power level insufficient.

Questions about this item

How loud does the 150 Watt rating get in a car cabin?

The 150 Watt amplifier drives the 6.5-inch driver to produce strong low-frequency output suitable for compact vehicle interiors.

What connection does the built-in amplifier use and what does it limit?

The subwoofer uses line-level RCA inputs, so the signal chain is limited by the head unit's pre-amp voltage.
