KICKER KQ30
Thirty bands of 12dB cut or boost at 1/3-octave spacing mean ultimate
frequency control in stereo or mono. A scorching 9-volt output lets you
pour on the signal to your amps.Adjustable input and output controls
for each channel add more control, and fast-acting clip indicators keep
things from getting too crazy.
KICKER KQ9
A ton of features are packed in this little half-DIN dash-mount box.
You get nine bands of 12dB cut or boost (one especially for bass), two
18dB/octave active crossovers (one high-pass and one low-pass), a
sub-bass output controller, and lots more.
KICKER KQ5
The KQ5 slices the spectrum into five bands with variable center
frequencies. Cut/boost is 12dB, and output is a strong 7 volts. Two
sets of inputs allow line switching, and front/rear outputs have fader
control. There's even a knob that lets you control bass boost on most
KICKER amps right from your dash.
