About the JBL Stage GT 90041
From our tech experts at CEN
A 4-channel amplifier from JBL, rated at 520w RMS.
Who it suits
Drivers who have upgraded their speakers and found the head unit cannot drive them properly.
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: Can the JBL Stage GT 90041 power a subwoofer?
A: Yes. Two channels can be bridged to give 260W x 2 at 4 ohms, so you can run front speakers from two channels and a subwoofer from the bridged pair, or bridge both pairs.
Q: Will the Stage GT 90041 work with a factory head unit?
A: Yes. It accepts high-level speaker inputs from 1V to 25V as well as low-level RCA inputs from 0.2V to 5V, and two high-level input cables are included in the box.
Q: What is in the box with the JBL Stage GT 90041?
A: The amplifier, two spare fuses, two high-level input cables, four mounting screws with washers, two Allen keys, two JBL stickers, a QR code for the manual and a safety instruction sheet.
