Our take on the JBL Grand Touring Series GTO301.1 IIby Crutchfield's Ken Nail
JBL Grand Touring Series II amplifiers create a sound and sight sensation. The aggressively modern amplifier case features a see-through cover which allows you to install internally-mounted neon tubes for an entrancingly cool backlighting effect.
The GTO301.1 II mono amplifier incorporates an efficient power supply that delivers a big sound with low distortion. A variable frequency filter adjusts the amp's output to best fit your system's specific needs. When you're craving more thump, the bass boost circuit kicks things up a notch.
The convenient top-mounted controls make it easier to set up and tweak your amp, while preamp outputs simplify adding another amp into your system. An optional wired sub level remote is available.

Low-pass Filter: The internal low-pass filter can be adjusted from 32 to 320 Hz, and has a slope of 12 dB per octave.
Bass Boost: For added low frequency performance, this amplifier has a 0 to +12 dB variable bass boost centered at 50 Hz.
Preamp Outputs: The preamp output jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. These outputs provide a full-range signal.
Protection Circuitry: To keep the amplifier safely operating, the protection circuitry is triggered in the following situations: DC voltage on amplifier output, overheating, over voltage, under voltage, and when there is a short circuit in the system.
Optional Neon Tubes: Using the supplied mounting clips, you can install optional Street Glow AN9 neon tubes in the amplifier. The neon tubes are installed by removing the amplifier's top panel, which is transparent plastic.
Optional Remote Level Control: The amp has an RJ-11 jack for use with the optional JBL remote level control (item #109JBLRLC). This will allow the subwoofer level to be adjusted from the listening position.
Power Connections: The power and ground terminals are set-screw terminals and will accommodate up to 4-gauge wire. The remote turn-on terminal will accept up to 8-gauge wire. A Phillips-head (not supplied) is required to tighten/loosen the terminals.
Speaker Connections: The set-screw speaker terminals will accommodate up to 8-gauge wire. A Phillips-head (not supplied) is required to tighten/loosen the terminals.
Remote Level Control: This RJ-11 jack is for use with the optional remote level control.
