Boston Acoustics GTA-800M
The Boston Acoustics GTA-800M is a mono amplifier that delivers 800 watts RMS to your subwoofer system. The Q-Tune™ technology lets you tune your bass to drive maximum performance from your sub/enclosure combination. The special noise cancellation circuitry ensures that your speakers churn out only crystal clear music. The variable high- and low-pass filters allows you to tune the amplified signal for maximum performance. Tweak the sub level right from the front seat with the optional remote control, which has been provided for added convenience.
