Features

CEA 2006 Compliant: The ZX300.1'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 "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 ZX300.1 has one pair of RCA inputs which will receive either high or low level signals from your car stereo. 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 by splicing RCA plugs onto the speaker wire or using an RCA-to-Speaker wire adapter (136CLR2SW, sold separately) , and setting the input level switch to "HI".

Auto Turn-on Selection: The ZX-series offers three different automatic turn-on modes that can be selected on the end panel. You can select from the following modes:

• Remote Turn-on: You can connect an 18-gauge 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 surge 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.
• Signal Sense Turn-on: This method detects the incoming audio signal from your source unit and automatically turns on the amp. This method will not work properly if the input gain control is not set properly.

Protection Circuitry: The ZX300.1's protection circuitry guards against accidents and undesired operation. The amp is protected by thermal protection, voltage protection, and short circuit protection. 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 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.

Optional ZX-Series End Caps: You can add the optional ZX-series amplifier end caps (2068ZXEC, sold separately) to this amplifier. These plastic end caps cover the wire terminals and controls located on the ends of the amp for a clean installation. When installed, the end caps add approximately 2-5/8" to the overall width of the amplifier.

Controls

Low-pass Filter: The internal low-pass filter, fixed at 80 Hz, can be switched on or off as needed. The filter 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.

KICKEQ Bass Boost: The ZX300.1's KICKEQ bass boost circuit provides a +12dB signal boost at 40Hz. The bass boost can be switched on or off as needed.

Remote Bass Level Control: The Remote Bass Level Control lets you adjust the output level of the amplifier from anywhere in the vehicle. When attached to the mounting bracket, the Remote Bass Level Control has the following dimensions: W=2.207", H=1.175", D=2.133" (including the knob). A 19' 9" cable is included for routing the remote bass level control signal to the front of the vehicle.
