3 w w w .jb l. co m Eng li sh MOUNTING THE AMPLIFIER NOTE: You may find it more convenient to make all of the connections to the amplifier before you permanently mount it to the vehicle. Before mounting the amplifier you must remove the two end caps to expose the mounting holes and the connections.
4 CONNECTING THE POWER AND GROUND The GTO series amplifiers are capable of delivering extremely high power levels, and require a heavy-duty and reliable connection to the vehicle’s electrical system to achieve optimal performance. Please adhere to the following instructions carefully.
5 w w w .jb l. co m Eng li sh Power Connection 1. Connect a wire (minimum 6AWG – 13.2mm 2 – for the GTO-5EZ; minimum 8AWG – 8.4mm 2 – for the GTO-3EZ) directly to the battery’s positive (+) terminal. 2. Install a fuse holder for a 90A fuse (GTO-5EZ) or 70A fuse (GTO-3EZ) on this wire within 18" (46cm) of the battery’s (+) terminal.
6 GTO-5EZ bridged operation (high-power for front speakers) • Connect the left speaker to the FL (+) and FR (–) terminals • Connect the right speaker to the RL (+) and RR (–) terminals. • Connect the subwoofer to the Sub (+) and (–) terminals.
7 w w w .jb l. co m Eng li sh INPUT CONNECTIONS The GTO-5EZ and GTO-3EZ amplifiers have multiple input connectors with routing switches that increase flexibility, so you can use these amps in a variety of audio system configurations.
8 seTuP PrOcedure GTO series amplifiers include a setup CD with test signals that makes it easy to precisely set the amplifier’s input gain to maximize the amplifier’s signal-to-noise and dynamic range performance with your vehicle’s audio system.
9 w w w .jb l. co m Eng li sh • Low-pass operation: The low-pass Crossover control setting you use for subwoofers will depend partly on the settings you use for the system’s high-pass channels (see above) and partly on the type and location of your system’s subwoofer.
10 BASS BOOST The Bass Boost control provides up to 12dB of bass boost at 45Hz. Set this control according to your personal taste, but be careful not to set the control at a high enough level to cause audible distortion or bottoming of your subwoofer.
