  This 4-channel amplifier has the most flexible crossover we offer. On both front and rear channels, it's variable from 40Hz to 200Hz and selectable for either stereo high pass or mono low pass. The "Non-Fading Summed Output" jacks provide a line level summed output of the right front/right rear and left front/left rear input signals. This output is typically used to drive an external subwoofer amplifier. The parallel input switch allows a 2-channel signal to drive all four channels (no need for a "Y" connector). This amp even has the MTX Audio Thunder EQ bass boost!
