Ultra compact micro bass amplifier
Vibe's latest amplifier technology delivers high performance in an incredibly small package. The Powerbox 400.1M puts out up to 400 W for bass, while its compact dimensions allow it to be fitted almost anywhere in the vehicle.
An ISOAWK kit (sold separately) makes this amp compatible with an ISO T harness, so it can plug directly into the existing stereo loom — supplying audio signal, power and earth without needing a separate cable run to the battery. To pair this amp with a capable subwoofer, the Vibe SLICK8D2-V3 8 inch subwoofer is a well-matched option.

About the Vibe POWERBOX400.1M-V7
From our tech experts at CEN
A monoblock subwoofer amplifier from Vibe’s Powerbox range, Class D, in a compact chassis small enough to hide under a seat.
Who it suits
Anyone adding a subwoofer that needs real power behind it. Micro amplifiers suit vans, campers and modern cars where there is nowhere to put a full-size chassis. Powerbox is Vibe’s long-running amplifier line, known for compact chassis.
Our tech experts advise
Matching matters more than headline watts, and gains want setting with a meter rather than by ear. It needs a fused feed from the battery on the correct cable gauge. 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: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: How much power does the Vibe Powerbox 400.1M produce?
A: It delivers 170 W RMS at 4 ohm, 250 W RMS at 2 ohm and 400 W RMS at 1 ohm, with 800 W peak.
Q: Can the Vibe Powerbox 400.1M plug into my existing stereo wiring?
A: Yes, with the ISOAWK kit (available separately), which makes it compatible with an ISO T harness so it plugs into the existing stereo loom in the vehicle. It can also be fitted with a Critical Link Rapid kit.
Q: How big is the Vibe Powerbox 400.1M?
A: It measures 37 x 157 x 82 mm (1.5" x 6.2" x 3.2"), small enough to fit in tight spaces.
