At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Terminology: Although the
ZX650.4 is a 4-channel
amplifier, Kicker uses the terminology of "Amp 1" and "Amp 2" to indicate the
channels.
CEA 2006 Compliant: The
ZX650.4's power ratings are measured according to the strict standards dictated
by the Consumer Electronics Association (CEA). These standards allow you to
accurately compare the rated power output of all CEA 2006-compliant amplifiers,
even if they come from different brands. Manufacturers who adhere to the
standards can display the CEA 2006 logo on their products and packaging.
Kicker "Living Loud" Certified
Power Certificate: The amplifier comes with a certificate that indicates the
total maximum wattage of the particular amplifier, along with the model number,
serial number, tested date, and whether the amplifier passed the total harmonic
distortion, signal-to-noise ratio, and protection circuit tests.
Speaker-level Inputs: Two
high-level input connections are included to allow use with sources that do not
have RCA preamp level outputs. If only one set of high level inputs is being
used, you can send the signal to all four channels when the Fader button on the
end of the amp is pushed out. Only one type of input signal (speaker-level or
line-level) should be used with this amplifier.
Built-in Variable Electronic
Crossovers: The amp features two independently-controlled crossovers that allow you to select
high-pass for satellite speakers, low-pass for subwoofers, or bypass for
full-range operation. The crossover frequency is variable from 50 to 200Hz.
KickEQ Bass Boost: The two
KickEQ bass boost circuits provide up to 18dB signal boost at 40Hz.
Fader Button: The unit has a
Fader button which gives you control of the output of the amplifier. If you are
using two sets of line-level or speaker-level inputs, the Fader button should be
pushed in so the receiver's fader control will operate properly. If only one set
of inputs is being used, the Fader button should be pushed out so the signal can
be sent to all four of the amplifier's channels.
SORT (Short circuit, Over-voltage,
Reverse polarity, Thermal)
Protection Circuitry: The SORT protection circuitry guards against
accidents and undesired operation. The Power LED on the left side of the amp
glows green and the power indicator on top of the amp glows red when the
amplifier is connected correctly and SORT has not been engaged. If the red
Protection LED illuminates, SORT has been engaged and the amplifier is in
protect mode until the problem is resolved.
Stereo Bridged Operation: You
can operate the ZX650.4 in a stereo bridged operation, with one amp driving two
full-range speakers and the other amp bridged to drive a single 4-ohm subwoofer.
This is also referred to as "3-channel" mode.

Wiring Recommendation
Amplifier Wiring: This
amplifier uses two 40-amp fuses, so its total fuse rating is 80 amps. If you are
using an amplifier wiring kit, it should include a fuse rated at a minimum of 80
amps. Some 4-gauge amp wiring kits carried by Crutchfield include a 60-amp fuse.
If you are using a kit with a fuse rated less than 80 amps, the fuse should be
replaced with an 80-amp fuse.
