About the JL Audio VX600/1I
From our tech experts at CEN
A monoblock subwoofer amplifier from JL Audio’s VXi Series, with digital signal processing built in, rated at 600w RMS.
Who it suits
Anyone driving a subwoofer that needs real, controlled power rather than a compact powered unit. VXi Series has full DSP on board, so amplification and tuning arrive together and can be networked with other VXi amplifiers.
Our tech experts advise
The processing is worth only what the tuning puts into it: measurements in the car, delays set for the driving seat, crossovers chosen for your drivers. It also 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 do I adjust the settings on the VX600/1i?
A: The VX600/1i has no traditional control knobs or switches. All amplifier adjustments and DSP functions are configured with the JL Audio TüN software on a compatible PC, tablet or smartphone, and a 6 ft USB A/B cable is supplied.
Q: What impedance can the VX600/1i run?
A: It is rated for 4, 3 and 2 ohm loads: 400 W, 500 W and 600 W RMS respectively at 14.4 V. A 1.5 ohm rating is not listed.
Q: What's in the box with the VX600/1i?
A: The amplifier, power connector, 14 inch analogue input harness (15-pin D-Sub to 4 RCA), subwoofer output connector, 18 inch speaker wire loom, Sub wire label, 6 ft USB A/B cable, 4 corner caps and corner cap tool, 2 silver thumbscrews, 2 black hex cap machine screws, 2.5 mm and 3 mm hex wrenches, JL Audio logo badge, connection guide and registration card.
