ZEUS has been delivering incredibly powerful and very affordable car audio amplifiers to the mortal car audio enthusiasts of Earth for decades. The new ZEUS line of amplifiers from Hifonics still maintains that throwback look of the original Hifonics amplifiers but they are packed with technology for great sound and huge power. People used to have to spend a thousand dollars for an amplifier like this, now it is the most affordable way to get started in real high end car audio design.

New this year, is a new 5 channel amplifier for the ZEUS family. This one amplifier can power a full audio system and not require the space of a typical 4 channel amp with a mono amplifier. Utilizing both Class A/B technology for sound quality and Class D for powerful bass this is a great system solution.
