About the Eton PA 4
From our tech experts at CEN
A 4-channel amplifier from Eton, Class D, rated at 45w RMS.
Who it suits
Drivers whose speakers have outgrown the head unit. Eton is a German manufacturer with a long history in both home and car audio.
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 Eton PA 4 deliver?
A: Channels 1/2 deliver 2 x 45W RMS at 4 ohms. The high-power channels 3/4 deliver 2 x 80W RMS at 4 ohms, 2 x 140W RMS at 2 ohms, or 1 x 280W RMS bridged at 4 ohms. Channels 1/2 do not support 2 ohm or bridged operation.
Q: Can the Eton PA 4 power a subwoofer?
A: Channels 3/4 can be bridged to give 1 x 280W RMS at 4 ohms, which can drive a subwoofer while channels 1/2 run a pair of speakers.
