Thank you for purchasing a JBL Grand Touring 2-way Component System. We’ve organized this manual to make your installation as simple and trouble-free as possible.
03 Component System Parts Your new Component System consists of the GTC04 neodymium magnet tweeter and either a 4", 5-1/4", or 6-1/2" midwoofer. Both the GTC04 and the midwoofer have high-quality passive crossover parts already built into them.

05 T weeter Output Level The GTC04 is a very efficient tweeter. If there is a need to lower the tweeter output level, a pair of 4 ohm / 5 watt resistors can be connected in series with the GTC04 as shown in Figure 3. To avoid short circuits, make sure that heat-shrink tubing or electrical tape is used to cover all exposed wiring.
06 Installation of the GT4.0c woofer as shown in Figures 4a and 4b. Removable Mounting Ears on GT4.0c Bend up and down repeatedly to break off or use tin snips. • Some Toyota installations may require mounting ears to be removed from opposite sides.

10 System Design There are a variety of system options available with the Component System. The simplest configuration is to use them full range with their built-in passive crossovers by connecting them to the output of a head unit or an amplifier (Figures 7 and 8).
11 Installation Warnings and T ips • Be careful not to cut or drill into fuel tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when work- ing on your vehicle. Inspect behind panels before you cut or drill. • Make sure that the midwoofer will physically fit in the mount- ing location.
12 A Note on Power Handling As a result of their high effi- ciency, all JBL loudspeakers will produce reasonable volume levels in the automotive environment using very little amplifier power. However, the use of a small amplifier to attain very high vol- ume levels could lead to over- driving the amplifier.
