About the Option Audio AIR-8 D2
From our tech experts at CEN
The Option Audio AIR-8 D2 is an 8-inch (20cm) dual voice coil car subwoofer rated at 200W RMS. Its dual 2+2 ohm coils allow wiring at 1 ohm or 4 ohm to suit your amplifier. A ferrite magnet, coated membrane cone, and fibreglass-reinforced plastic basket support consistent, long-term performance.
Who it suits
The AIR-8 D2 suits drivers who want a versatile 8-inch subwoofer that works with a range of amplifiers and enclosures. If space is tight, the AIR-F8 D2 delivers the same 200W RMS in a shallower, flat profile. For more output, the AIR-10 D2 steps up to 10 inches and 300W RMS.
Our tech experts advise
The 7.6cm mounting depth suits most sealed or ported enclosures; measure your available space before ordering. Wire the coils in parallel for 1 ohm or in series for 4 ohm, depending on your amplifier's stable impedance. Subwoofer installation is priced per vehicle at CEN — see our fitting service 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: How much power can the Option Audio AIR-8 D2 handle?
A: It is rated at 200W RMS.
Q: What is the mounting depth of the AIR-8 D2?
A: It needs 7.6cm of installation depth.
Q: Can the AIR-8 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.
