Not everybody wants an amplifier that they can surf on. People need space, have kids and lease cars. The new Stealth series of amplifiers not only have the smallest footpring for big power, they are also stackable. Having 5 channels of amplification with over 1000 watts can be the size of an average showbox! There are 2 sizes with 3 models each to fit every application. And while most small amps these days are Class D, the Stealth amplifiers are all Class A/B for the purest, uncolored sound reproduction. Diamond quality sound and dynamite power prove that some of the best things come in small packages!
