OR NEON TUBES
The JBL A6000/A3000GTi amplifier
is equipped with an internal fuse, a
20-inch neon tube and two 6-inch neon
tubes. Should the fuse or a neon tube
fail, perform the following steps
to replace the part:
NOTE: For neon tube replacement, see
your authorized JBL car audio dealer to

®
neon tubes
in 6- or 20-inch sizes.
NOTE: Although the following
steps discuss and illustrate how
to disassemble a JBL A6000GTi,
the disassembly procedure for a
JBL A3000GTi is similar.
1. Disconnect and unmount the
amplifier from the vehicle. On a
soft surface, turn the amplifier over
to view the bottom. Using a T-25
screwdriver, remove the four large
Torx-head screws along the bottom
edges and set them aside (see
Figure 14).
2. Turn the amplifier over to view the
top. Using a 5⁄32-inch Allen wrench,
remove the four cap screws on the
clear cover and set them aside (see
Figure 14).
3. Slide the clear cover off and set it
aside (see Figure 14).
