If you want to look for real sound improvement, the solution is here with Blaupunkt's new GTA DSP amplifier series. Built with a newly developed and sophisticated circuit board layout, this GTA DSP amplifier redefines "world class". The integrated 25/56 bit DSP gives you the possibility to individualize the sound in your car. Just the way you like it. Along with the new design, the housing volume has been reduced by approx. 21% making installation possible in most compartments in your vehicle. Needless to say, the GTA DSP amplifier still maintains its essence of GTA amplifiers - High Power Output for Little Money.
