About the Helix K330814
From our tech experts at CEN
An 8 inch subwoofer supplied in its own compact enclosure, firing downwards so it can sit under a seat or in a footwell and use the floor to couple into the cabin, with dual voice coils for flexible wiring.
Who it suits
Drivers who want real bass without losing the boot or commissioning a custom build. Compact enclosures suit cars, vans and campers where space is the binding constraint.
Our tech experts advise
Even a matched enclosure needs the amplifier set correctly and the crossover point chosen against your front speakers, otherwise it draws attention to itself instead of filling in underneath. Installation and tuning are priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

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: 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: Does the HELIX IK E8.1-DVC2 come in a ready-made box?
A: Yes. It is a complete ported downfire enclosure with the 8 inch HELIX IK W8-DVC2 driver already installed, so you only need to add an amplifier and wiring.
Q: What impedance can the IK E8.1-DVC2 be wired to?
A: The connection terminal lets you configure it as 2 x 2 ohms, 1 x 4 ohms or 1 x 1 ohm to suit your amplifier.
Q: How big is the IK E8.1-DVC2 enclosure?
A: It measures 184 x 310 x 285 mm (H x W x D).
