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.
