Having Crystal clear sound without breaking the bank on a 4 channel amp is not only controllable within your sound system and is possible at down4sound. Most will argue that class ab amplifiers are the way to go; it’s an old-school quality sound. This is our most affordable 4 channel amp with class ab technology within the Down4Sound lineup.

This 4-channel amplifier use clip indicator lights for distortion free sound and delivers great sound better than most 4 channel amps in its very affordable price range. How many speakers can you run on class ab? That is probably all; you must get the impedance and power output right. More speaker-level inputs mean more power will be needed. Your audio system when it comes to the pure control of car amplifiers and, more specifically, 4 channel car amplifiers that are class ab, this amp is all that you need within your car stereo system. Again Class ab is argued to be the best sound quality by most enthusiasts today . We made this class ab 4 channel car amplifier with good sound quality DNA and great hardware to keep the old-school argument live and well for sound quality and 4 channel car amplifier.
