6.5-inch car subwoofer replacement

The 5 Core WF-672 is a 6.5-inch subwoofer built for car-door or hood mounting as well as home and pro-audio enclosures. It handles 30 watts RMS and 60 watts maximum power at a 4-ohm impedance. A stamped steel frame keeps the motor assembly aligned during high excursion.

Mounting constraints for 6.5-inch drivers

The unit requires a 5.25-inch cutout and 2.375 inches of mounting depth behind the baffle. Kapton paper heat sinks aid thermal dissipation so the voice coil sustains voltage under continuous load. Lead-free solder joins the coil wire, tag and copper tensile wire for a reliable connection.

30 watts RMS power handling

This RMS figure determines whether the subwoofer matches your amplifier output and desired listening level. Builders needing more continuous power or a different impedance should consider other models. The ferrite magnet and forged iron T-yoke provide the motor force for the specified rating.

Questions about this item

Should I choose the 30-watt RMS or the 60-watt max version of the WF-672?

The WF-672 is a single model rated at 30 watts RMS continuous power and 60 watts peak power; there are no separate versions to choose between.

What does the 30-watt RMS rating mean once the subwoofer is installed in my car?

It means the driver can handle 30 watts of continuous amplifier power without overheating, thanks to the Kapton paper heat sinks and 4-ohm impedance.

What interface does the WF-672 use and what does that cap in practice?

It connects via standard speaker wire terminals to a 4-ohm amplifier output; the 4-ohm load determines how much current the amp can deliver.
