Stage 800BA Subwoofer

THANK YOU for choosing the JBL Stage 800BA powered subwoofer. To ensure maximum performance, we strongly recommend that you have it installed by a qualified professional – while these instructions offer general installation guidance, they do not show specific installation methods for your particular vehicle. If you do not have the necessary tools or hands-on experience, do not attempt the installation yourself; instead, ask your authorized JBL car-audio dealer about professional installation options.


IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.
• Always wear protective eyewear when using tools.
• When making electrical connections, make sure they are secure and properly insulated.
• If you must replace the fuse, be sure to use the same type of fuse and current rating as that of the original.


Choose a location that doesn’t prevent you from loading or unloading cargo, interfere with fold-down seats, or keep you from being able to open or close the trunk lid, or interfere with the safe operation of the vehicle.

You’ll make all signals and connections, and adjust all settings at the panel on the back of the Stage 800BA.

The package includes a wiring harness that features all necessary wires for power, ground, and signal, and plugs into the “INPUT” connector on the back panel of the Stage  800BA. It also includes a pair of RCA adapters for use with speaker-level inputs.

Wiring harness
+12V 16AWG Red
GND 16AWG Black
Remote in 22AWG Blue/white

Speaker-level input adapters
RCA White – left
Red – right
L+ 22AWG Gray
L- 22AWG Gray/Black
R+ 22AWG Green
R- 22AWG Green/black


Connect the end of the red 16-gauge power wire to your vehicle’s + (positive) battery terminal. Note: If an extension cable is necessary because of your mounting location, we recommend that you connect the extension to the power wire using solder. You must also install a fuse holder with a 10A fuse in-line and within 18″ of the battery.


Connect the 16-gauge black ground wire to a solid, metal point on the vehicle’s chassis using a ring terminal. Use sandpaper to clear the paint from the metal surface at the chassis location. Use a star-type lock washer to secure the wire.


If you’re using line-level inputs to provide a signal to the Stage 800BA (see below), uncouple the bullet connector on the blue/white wire, and connect the longer wire marked with “REMOTE IN” to the remote output wire on your source unit.

If you’re using speaker-level inputs to provide signal to the Stage 800BA (see below), you must leave the bullet connector coupled so that the blue/white wire makes a loop.

When you’ve made all the necessary power and signal connections to the Stage 800BA wiring harness, plug the harness into the input marked “INPUT”.


If your head unit has single or dual subwoofer outputs, use RCA patch cables to connect them to the line-level inputs of the Stage 800BA harness. For single subwoofer outputs,  use an RCA Y-adapter cable to connect to the Stage 800BA line-level inputs. If your head unit offers stereo subwoofer outputs, connect to the line-level inputs of the  Stage 800BA harness using stereo RCA patch cables.


If your head unit only has speaker-level outputs, use the included speaker-level input adapters. Splice the gray and gray/black wires into your vehicle’s front left speaker wires,  and the green and green/black wires into your vehicle’s front right speakers wires (using solder is recommended). Then plug each adapter in to the RCA inputs of the Stage  800BA harness.


If you’re using a compatible JBL RBC remote bass level controller (sold separately at https://www.jbl.com), plug its connector directly in the REMOTE input on the back panel.


The back panel includes two LED indicators. When POWER is illuminated, the Stage 800BA is turned on. When PROTECT is illuminated, the Stage 800BA has entered protect mode due to overheating or over/under-voltage conditions.


Adjusting the gain lets you match the input sensitivity of Stage 800BA with the output of your receiver, and match the relative volume to the rest of the speakers in your vehicle.  1. Start with gain control set to minimum, and the crossover control and bass control rotated midway.
2. Choose music with substantial bass content and turn the volume control on your receiver to ¾ of its total output.
3. Adjust the gain control clockwise, listening carefully to the bass output. If you hear distortion, turn the gain control counterclockwise to decrease the gain.

4. Switch the phase back and forth between 0 and 180 degrees to determine which setting provides the cleanest bass output.

5. Adjust the crossover control (between 60Hz and 200Hz) until the Stage 800BA plays only low-frequency information – you should not hear elements such as vocals coming from the woofer.

6. Adjust the Bass EQ control clockwise or counterclockwise between 0 and 9 dB to enhance the bass output to suit your taste.

A Message from the JBL manufacturer and the Consumer Electronics Association:

Selecting fine audio equipment, such as the unit you have just purchased, is only the start of your musical enjoyment. Now it is time to consider how you can maximize the fun and excitement your equipment offers. JBL and the Electronics Industry Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level; one that lets the sound come through loud and clear without annoying blaring or distortion – and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. What sounds “normal” can actually be loud and harmful to your hearing. Guard against this by choosing a safe level BEFORE your hearing adapts.
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. What sounds “normal” can actually be loud and harmful to your hearing. Guard against this by choosing a safe level BEFORE your hearing adapts.

• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably, clearly, and without distortion.
• Do not exceed that level.

Taking a moment to do this now will help to prevent hearing damage or loss in the future. After all, we want you to listen for a lifetime.
