About the Option Audio AIR-F8 D2
From our tech experts at CEN
The Option Audio AIR-F8 D2 is an 8 inch shallow-mount dual voice coil flat subwoofer rated at 200W RMS. Its 4.3cm installation depth makes it suited to vehicles where a conventional subwoofer will not fit. The neodymium magnet keeps weight low without sacrificing efficiency.
Who it suits
This sub suits drivers who want genuine bass but have limited mounting space in their vehicle. The dual voice coil configuration wires to either 1 ohm or 4 ohm, giving useful flexibility when matching an amplifier. For a more compact option, see the AIR-F6 D2 6.5 inch 150W RMS flat sub.
Our tech experts advise
The AIR-F8 D2 is a bare driver only — it requires a separate enclosure or a custom-built baffle. Confirm your amplifier's rated output matches the wiring impedance you choose before purchasing. Fitting costs vary per vehicle; visit our Nottingham car audio installation page for details.

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-F8 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-F8 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 much power can the AIR-F8 D2 handle?
A: It is rated at 200W RMS, delivering deep bass from a shallow 8-inch design.
Q: What is the installation depth of the AIR-F8 D2?
A: The AIR-F8 D2 needs just 4.3cm of installation depth, so it suits vehicles with very limited space.
