The enclosure is coated with Roadkill Armor and wrapped in marine-grade vinyl. Internal bracing and poly-fibre fill reduce resonance and improve bass accuracy. The dual front mounting baffle positions the driver for optimal sound dispersion.
Installation uses a quick-disconnect harness and connector. A powder-coated steel grille and multi-secure mounting system are included as standard.
For best results, pair the SPK-V8 with a matching AudioControl amplifier. If you need to integrate the system with a factory head unit, AudioControl's LC2i line output converter provides a clean signal feed with AccuBASS correction.

About the AudioControl SPK-V8
From our tech experts at CEN
An AudioControl 8 inch subwoofer.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it: box volume and tuning decide what you actually hear. We build enclosures to suit both driver and vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs.

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 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: Is the subwoofer included with the SPK-V8?
A: Yes. The SPK-V8 is a loaded vented enclosure supplied with an 8-inch Spike Series 2 ohm subwoofer fitted.
Q: What is the SPK-V8 tuned to?
A: The port is tuned to 33Hz with an F3 of 39Hz. AudioControl recommends a subsonic filter setting of 33Hz.
Q: How big is the SPK-V8 enclosure?
A: It measures 15.75in wide and 11.02in high, with a depth of 12.13in at the top and 13.74in at the bottom.
