    "Good size & Works...Gets the job done...All in all I am very pleased with the amp, saves a ton of time installing over traditional 4 channel amp and running a bunch of wires from the speakers to the amp etc...now I am not comparing this amp to larger more powerful units that shred out 300 to 1000 watts, they are a different breed what this amp does it it provides music that adult listeners normally listen to and can handle different forms of music very well"
