SETTING UP THE GTi AMPLIFIER

REPLACING THE FUSE 
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 purchase new StreetGlow

®

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).

logo badge assembly.

4. Using a T-15 screwdriver, remove

the four Torx-head screws around
the output panel and set them aside
(see Figure 15).

5. Repeat Step 4 for the input panel

(see Figure 15).

6. Remove the cover and set it aside

(see Figure 15).
