VX 300W 4-Channel Class D Full-Range Amplifier
53VXA3004
The VXA300.4 is a compact 4-channel Class D amplifier designed for clean, efficient performance. It suits both factory and aftermarket audio system upgrades without taking up excessive installation space.
It produces 75W RMS per channel at 2 ohms, or 150W x 2 when bridged, making it well suited to driving front and rear speakers with greater clarity and volume. KICKER FIT™ (Fail-safe Integration Technology) enables compatibility with most OEM and aftermarket head units, while automatic turn-on circuitry and start/stop vehicle compatibility simplify installation in modern vehicles.
Variable 12dB crossovers and KickEQ™ bass enhancement allow system fine-tuning, adding low-frequency impact without compromising overall sound quality. The Class D design reduces current draw and heat generation, keeping the chassis compact.

About the Kicker 53VXA3004
From our tech experts at CEN
The Kicker 53VXA3004 (VXA300.4) is a compact 4-channel Class D car amplifier rated at 50W x 4 RMS at 4 ohms, rising to 75W x 4 at 2 ohms or 150W x 2 bridged at 4 ohms. KICKER FIT™ technology handles integration with factory and aftermarket head units, including automatic turn-on via DC offset. A variable 12dB crossover and KickEQ™ bass boost allow straightforward system tuning.
Who it suits
The VXA300.4 suits drivers wanting noticeably better clarity and volume from front and rear speakers without filling the boot. Its compact footprint is a practical choice for vehicles with limited installation space. For a step up with built-in DSP processing, consider the Kicker KEY200.4.
Our tech experts advise
Check speaker impedance before fitting: the amp runs cleanest at 4 ohms per channel. High and low-level inputs accept signals from 125mV to 10V, so it works with most source units. Start/stop vehicle compatibility is built in, which suits many modern cars. Installation is priced per vehicle — speak to our Nottingham team to arrange a fitting.

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 Kicker VXA300.4 produce?
A: 50 watts RMS x 4 at 4 ohms, 75 watts x 4 at 2 ohms, or 150 watts x 2 bridged at 4 ohms.
Q: Can the VXA300.4 run from a factory stereo?
A: Yes. It accepts high and low level inputs, uses KICKER FIT technology for OEM integration and turns on automatically via DC offset.
Q: Is the VXA300.4 compatible with start/stop vehicles?
A: Yes. It is compatible with start/stop vehicle systems.
