About the Option Audio AIR-F6 D2
From our tech experts at CEN
The Option Audio AIR-F6 D2 is a 6.5 inch (16.5cm) shallow-mount dual voice coil subwoofer with 150W RMS power handling. Its installation depth of 3.5cm suits vehicles where space behind a panel or under a seat is severely limited. The neodymium magnet keeps weight low without reducing efficiency.
Who it suits
It is ideal for drivers who want more bass but have no space for a conventional deep driver — under a seat or behind a trim panel, for example. If space allows a deeper installation at the same power, the AIR-6 D2 is the standard-depth equivalent. For more output in a flat housing, consider the AIR-F8 D2 at 200W RMS.
Our tech experts advise
The dual voice coil wires to 1 ohm or 4 ohm — confirm your amplifier's stable impedance before connecting. This is a driver only; you will need a sealed enclosure or a custom-built shallow mounting. Installation cost varies by vehicle; speak to our team at our Nottingham workshop for a fitting quote.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Can the AIR-F6 D2 be wired to 1 ohm or 4 ohms?
A: Yes. It has dual 2 ohm voice coils, which can be wired to give a 1 ohm or 4 ohm load to suit your amplifier.
Q: Does the AIR-F6 D2 come with an enclosure?
A: No. It is supplied as a single subwoofer chassis (driver only), ready to install in a suitable enclosure or space.
Q: How deep is the AIR-F6 D2?
A: It needs only 3.5cm of installation depth, ideal for special installation situations and vehicles with limited space.
