About the Vibe PULSECBR12A-V4
From our tech experts at CEN
An active Vibe subwoofer, 12 inch, with the amplifier built in, rated at 350w RMS.
Who it suits
Drivers who want bass without finding room for a separate sub, amplifier and enclosure. Compact active units are the usual answer where boot space is not negotiable.
Our tech experts advise
It still needs a fused feed from the battery and a signal source, and the level and crossover want setting against your existing speakers so it fills in rather than booms. Installation is 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 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: Does the Vibe PULSECBR12A-V4 have a built-in amplifier?
A: Yes. It is an active enclosure with an on-board class D DSP amplifier, so no separate subwoofer amplifier is needed.
Q: Can I adjust the Vibe Pulse 12A from my phone?
A: Yes. The app and built-in DSP give control of EQ, phasing, Q factors and slopes.
Q: Will the Vibe Pulse 12A fit a shallow boot?
A: It is designed for vehicles with small or shallow boot space, measuring 355mm high, 550mm wide and 288mm deep.
