6.5 Inch Subwoofer Pair

This 5 Core subwoofer pair delivers 30W RMS and 330W peak power per unit at 4 Ohm impedance. The 6.5 inch drivers suit car audio replacement in doors, under seats or factory speaker holes. Buyers seeking higher SPL or deeper extension than 30W RMS provides should consider larger drivers.

Integration With Factory Locations

Standard 6.5 inch sizing fits most OEM openings without custom brackets, freeing installers from cutting panels. The 4 Ohm load works with common aftermarket amplifiers and head-unit outputs, while 86 dB sensitivity reduces the power needed for a given volume level. Systems requiring dual voice coils or 2 Ohm wiring are not supported.

Thermal Management And Power Draw

An advanced airflow cooling design and steel frame dissipate heat during extended play, protecting the .81 inch CCAW voice coil and 8 Oz Y30 magnet. At 30W RMS the pair draws modest current from the vehicle electrical system, limiting battery strain. Continuous operation above rated RMS will increase thermal load beyond the venting capacity.

Questions about this item

How much continuous power can each 6.5 inch subwoofer handle before overheating?

Each driver is rated for 30 W RMS continuous power; the steel frame and ventilated design help dissipate heat during long sessions.

What noise or thermal behaviour should I expect when the pair runs all day?

The advanced airflow cooling system prevents overheating, so the woofers maintain consistent output without thermal compression during extended play.

What amplifier specs do I already need to drive these 4 ohm woofers properly?

An amplifier stable at 4 ohms per channel and able to supply around 30 W RMS per channel will match the 86 dB sensitivity and 30 W RMS rating.
