Features

CEA 2006 Compliant: The ZX750.1's power and signal to noise ratio ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the output ratings of all CEA 2006-compliant amplifiers, even from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. The manual lists two signal to noise ratios:

• CEA 2006 compliant: 68 dB (ref: 1W, A-weighted)
• At rated Power: >95 dB (A-weighted)

Kicker Livin' 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.

Dual Input Sensitivity Differential RCA Inputs: The ZX750.1 has one pair of RCA inputs which will accept either high or low level signals. The unit has an input level switch that allows you to select a low- or high-level input; a low-level signal from the stereo's preamp output is recommended. If the stereo lacks preamp outputs, you can use the unit's speaker-level outputs; attach RCA plugs onto the speaker wire (adapter item number 136XDCLR2S) and set the input level switch to HI.

Auto Turn-on Selection: The ZX-series offers three different automatic turn-on modes; select from:

• Remote Turn-on: connect a wire from the remote turn-on lead from your source unit to the REM terminal on the amplifier; this is the preferred turn-on method
• DC Offset Turn-on: the DC offset mode detects a 6-volt DC offset from the high-level speaker outputs when the source unit is turned on; if remote turn-on is not an option, this is the next best choice; the REM terminal will have +12V out for turning on an additional amplifier
• Signal Sense Turn-on: detects the incoming audio signal from your source unit and automatically turns the amp on; will not work if the input gain control is not set properly; the REM terminal will have +12V out for turning on an additional amplifier

Protection Circuitry: The ZX750.1's protection circuitry guards against damage and undesired operation. The amp is protected by thermal protection, voltage protection, and short circuit protection. The power indicator on top of the amp glows red when the amplifier is connected correctly and the protection has not been engaged. If the red Protection LED illuminates, the amp's protection circuit has been engaged and the amplifier is in protect mode until the problem is resolved.

Controls

Low-pass Filter: The internal low-pass filter is continually adjustable from 50 to 200 Hz and has a slope of 24dB per octave.

Subsonic Filter: The subsonic filter allows the amplifier to block ultra-low frequencies that your subs can't reproduce, improving the efficiency of your speaker system. The filter is fixed at 25 Hz, and has a slope of 24dB per octave.

Bass Boost: The ZX750.1's bass boost circuit provides up to 18dB signal boost at 40Hz. The bass boost circuit is continuously adjustable from 0 to 18dB.

Remote Bass Level Control: The included Remote Bass Level Control lets you adjust the output level of the amplifier from anywhere in the vehicle. A 19' cable is included and when attached to the mounting bracket, the Remote Bass Level Control has the following dimensions:

• Width: 2.212"
• Height: 1.193"
• Depth: 1.727" (2.367" including the knob and cable)

Amp Wiring Kit: Kicker recommends using a 4-gauge wiring kit with this amplifier.

Warranty

Warranty Note: The warranty on this amplifier is 2 years parts and labor. If the amp is installed using a qualifying Kicker amplifier wiring kit, in this case item number 20609PK4, the warranty is extended to 3 years parts and labor. The amp and wiring kit must be purchased on the same invoice from an authorized Kicker dealer (Crutchfield for example) and the warranty extension is only valid in the USA.
