About the Vibe POWERBOX65.4-8DSP
From our tech experts at CEN
A 4-channel amplifier from Vibe’s Powerbox range, with DSP on board.
Who it suits
Drivers whose speakers have outgrown the head unit. Powerbox is Vibe’s long-running amplifier line, known for compact chassis.
Our tech experts advise
The processing is worth only what the tuning puts into it, and that means measurements in the car rather than a preset. 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: Does the Vibe Powerbox 65.4-8 DSP have Bluetooth?
A: Yes. It accepts Bluetooth as well as optical and high level inputs, so it can turn a factory sound system into a Bluetooth receiver for wireless music streaming.
Q: How is the DSP in the Powerbox 65.4-8 DSP set up?
A: Through Vibe's smartphone app, which controls gain, crossovers, time alignment, a 31-band parametric EQ and an integrated mixer that can route a stereo input to four speakers.
