About the Hertz CP 4.800
From our tech experts at CEN
A 4-channel amplifier from the Hertz Cento line, rated at 760w RMS. Enough channels for a front and rear stage, or a front stage with the remaining channels bridged onto a sub.
Who it suits
Drivers who have upgraded their speakers and found the head unit cannot drive them properly. This is the step that makes good speakers sound like good speakers.
Our tech experts advise
Power figures mean little until the amplifier is matched to the speakers and the gains are set 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: Can the Hertz CP 4.800 power a subwoofer as well as speakers?
A: Yes. In 3-channel mode it delivers 100W x 2 plus 400W x 1 into 4 ohms, or 190W x 2 at 2 ohms plus 380W x 1 at 4 ohms. Sub level can be adjusted with the optional HRC 02 remote.
Q: Is the CP 4.800 suitable for electric vehicles?
A: Yes. It operates on a 9 to 18 VDC supply, which Hertz specifies as suitable for electric vehicles.
Q: What fuse does the CP 4.800 use?
A: It uses a single 40A fuse, with a nominal supply voltage of 11 to 15 VDC.
