GTA Series High Performance AmplifierSonic Electronix is now carrying the new 2011 line of Boston Acoustics GTA Series Amplifiers. These amps come in Monoblock, 2-Channel, 4-Channel, and 5-Channel configurations as well as numerous different power ratings. Each one these GTA Series amplifiers feature a wrap-around heatsink design, SST (Symmetrical Signal Topology), IMS (Integral Mounting System), 3-way protection circuitry, fully adjustable Q-Tune circuitry, and much more.
The GTA-1105 is a 5-channel version of this series and has an RMS power rating of 70 watts x 4-channels + 250 watts x 1-channel wired at 4 ohms and 125 watts x 4-channels + 400 watts x 2-channels wired at 2 ohms. It is equipped with gold-plated RCA level inputs & screw terminals and is powered by a MOSFET power supply. The option of low-level, or high-level inputs will allow the installation of these amplifiers into any system with ease. The fully adjustable low-pass/high-pass crossovers will allow for complete control of all frequencies allowing for personalized tuning of your audio system to better meet your musical needs and preferences. GTA amplifiers offer high performance with advanced features and technologies.

Decided to go with this 5 channel amp instead of two. I'm using this amp with a Fahrenheit TI-769NB, two sets of Infinity kappa speakers for the cab and a 12" Boston Acoustics sub. The sound is crisp, clear, and the sub def sounds great. The amp offers excellent controls to help get the clearest sound possible. Would def recommend!!
