Plug-and-play micro 4-channel amplifier
Vibe's Powerbox micro amp range delivers high performance in a very small footprint. The 4-channel Powerbox 65.4M provides 4 x 65 W for speakers, while the companion Vibe Powerbox 400.1M mono amp handles up to 400 W for bass. The compact size makes both easy to install in tight spaces.
The 4-channel amp includes a +12 V remote output and daisy chain signal output, making it a useful building block for a larger system.
An optional ISO T harness connects directly to the head unit, supplying audio signal, power and earth — no separate cable run to the battery required. For the bass amp, an ISOAWK kit (available separately) provides the same plug-and-play ISO T harness compatibility.

About the Vibe POWERBOX65.4M-V7
From our tech experts at CEN
The Vibe Powerbox 65.4M (POWERBOX65.4M-V7) is a micro Class D 4-channel car stereo amplifier producing 4 x 65 W at 4 ohms, 520 W peak. Its chassis measures 37 x 187 x 82 mm, compact enough to mount in tight spaces under seats or behind panels. A Molex to ISO connection is included for direct OEM head unit compatibility.
Who it suits
A good choice for anyone upgrading factory speakers while keeping the original head unit. The small footprint suits cars where installation space is limited. For a system with added bass, it pairs well with the Vibe Powerbox 400.1M mono sub amplifier.
Our tech experts advise
The crossover switches between high-pass and full-range at 50 Hz. The +12 V remote output and daisy chain signal output let you add a mono sub amp later without rewiring. This amp is rated at 4 ohms per channel — check your speakers before fitting. Installation is priced per vehicle; see our Nottingham car audio fitting service.

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 powerful is the Vibe Powerbox 65.4M?
A: It delivers 4 x 65 W at 4 ohms, with 520 W peak power, and has a frequency response of 50 Hz to 20 kHz.
Q: Can the Powerbox 65.4M be installed without running a power cable to the battery?
A: Yes. The 4 channel amp can be fitted with an ISO T harness direct to the head unit, which supplies audio signal, power and earth, so there is no need to run a separate cable to the vehicle's battery.
Q: How big is the Vibe Powerbox 65.4M?
A: It measures 37 x 187 x 82 mm (1.5 x 7.4 x 3.2 inch).
