Part of the VXi range; multiple VXi amplifiers can be networked together using the VXi-HUB (sold separately). For a lower-power 5-channel VXi option, see the VX700/5i.
NexD2™ amplifier technology
Every VXi amplifier combines JL Audio's NexD2™ switching amplifier technology with a fully integrated digital signal processor. The main channels use a DSP-controlled, full-range NexD2™ circuit with a reduced loop area design and DirectFET™ outputs, delivering low noise and high efficiency. The subwoofer channel uses an optimised low-frequency variant of the same NexD2™ technology.
The VX1000/5i drives four main speakers at 75 W x 4 @ 4 Ω while simultaneously powering a subwoofer at up to 600 W @ 2 Ω. Bridging the main channels converts the unit into a 3-channel system amplifier: 200 W x 2 @ 4 Ω on the main channels and 600 W @ 2 Ω on the subwoofer channel.
DSP control via TüN software
There are no traditional knobs or switches. All amplifier adjustments and DSP functions are configured through a compatible PC, tablet or smartphone running JL Audio's TüN™ software application.
Compact chassis and installation
The ultra-compact chassis places all connections on one side, simplifying installation in tight spaces.

About the JL Audio VX1000/5I
From our tech experts at CEN
A 5-channel amplifier from JL Audio’s VXi Series, with digital signal processing built in, rated at 1000w RMS.
Who it suits
Drivers whose speakers have outgrown the head unit, or who are building a front stage where each channel has a defined job. 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 VX1000/5i?
A: The VX1000/5i 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: How many speakers can the VX1000/5i power?
A: It is designed to power a complete system: four main speakers on its main channels plus a subwoofer on its dedicated subwoofer channel, rated up to 600 W RMS into 2 ohms.
Q: What's in the box with the VX1000/5i?
A: The amplifier, power connector, 14 inch analogue input harness (25-pin D-Sub to 8 RCA), 18 inch ABCD speaker output harness, 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.
