About the Boston Acoustics GTA-802
Boston Acoustics GTA amplifiers use some of the same technologies found in their top-of-the-line GT Reference amps to give your music a powerful boost. And these attractive amps deliver the sonic goods at a reasonable price.
The 2-channel GTA-802 amplifier puts out 80 watts RMS per channel — plenty enough power to rock a set of speakers or components — or you can drive a 4-ohm sub with 260 watts RMS in single-channel mode. Boston Acoustics' Q-Tune™ technology lets you bump up your bass, whether you're running a subwoofer or not. The inputs feature special noise-cancellation circuitry that ensures clean reproduction of your music all the way through to your speakers.
You'll find all connections and adjustment controls recessed on one side of the amp, for a neat installation and easy adjustment. Variable high- and low-pass filters let you tune the amplified signal so your system can sound its best. An optional wired remote control gives you the power to tweak your subwoofer's level from the front seat.

Features
2-Ohm Stable: The GTA-802 can be connected to loads with impedances as low as 2 Ohms; the lower the impedance, the higher the output power:
- 80 watts x 2 @ 4 ohms
- 130 watts x 2 @ 2 ohms
- 260 watts x 1 @ 4 ohms (bridged)
Controls and Terminals: All the controls and terminals are conveniently mounted on one side of the amp.
Controls
Gain: Adjust the input sensitivity with this rotary control; the range is 0.2 Volts to 5.0 Volts (line-level) or 0.4 Volts to 10.0 Volts (speaker-level).
Crossover Switch: Choose from high-pass, low-pass, and off (full range) for the crossover.
Crossover Frequency: The crossover (low-pass or high-pass) point is continuously variable from 50 Hz to 200 Hz; the slope is 12 dB/octave.
Q-Tune: Turn the Q-Tune on/off; the boost is +6 dB at 45 Hz.
Connections
Power/Remote: Three set-screw terminals for connecting power, ground, and remote wires; each terminal accepts up to 8-gauge wire; the set screws are tightened/loosened with the supplied 3mm Allen wrench.
Line-level Input: Left and right RCA jacks for the input signal from the head unit.
Speaker-level Input: Use the included harness when the receiver has no RCA outputs.
Speaker Output: Two pair of set-screw terminals provided for connecting the speakers; the terminals can accept up to 8-gauge wire; the set screws are tightened/loosened with the supplied 3mm Allen wrench.
GTA-RSL: RJ-14 port; connect an optional GTA-RSL remote level control (item number 065GTARSL, sold separately); the GTA-RSL is only functional when the low-pass crossover is engaged.
ATO Fuse: A single 30-amp ATO-type fuse is located between the speaker and power terminals.

This amp rocks. Plain and simple. I don't think this could be a better value. I have it running bridged to one single 12 inch sub, with the amp gain up about 75% of the way. The sub BANGS, and the sound quality is fantastic. Great amp, no complaints.
