use this control to match the outputs of your head unit to the amplifier.Starting with your head unit set at about the 2 o’clock position, increasethe amp level control until distortion begins to occur, and reduce slightlyfrom this point.

this amp features gold-plated RCA input jacks for high impedance input.Use these with car stereo output which uses RCA-type connector cables.

if your car stereo lacks RCA-type output jacks, you may connect speakeroutput leads to these input connectors.

this indicator is illuminated when power is applied.

the fuse protects the amplifier and your car’s electrical system from shortcircuit conditions.

use these connectors to deliver power, ground and remote turn-on controlto the amplifier.

these terminals are 14K gold plated to guarantee high conductivity andminimum signal loss.

when used with normal, full range systems, set this switch to “FULL.” Ifyou wish to use the internal crossover to power a driver of specific frequencyrange, use the “LOWPASS” or “HIGHPASS” settings.


when the crossover selector switch is in “low pass” mode, this controlsets the upper frequency limit for audio program sent to the speakers.

when the crossover selector switch is in “high pass” mode, this controlsets the lower frequency limit for audio program sent to the speakers.

this control permits adjustment of the bass level up to an increase ofapproximately 18 dB.




this indicator is illuminated when built-in protection circuitry is activated.

wiring tipsWhen making electrical connections to your amplifier, please observe thefollowing:

Use at least 8 gauge wire for power and ground connections.

Wire the amplifier directly to the car battery.

For the ground connection, use the shortest possible wire to a good chassis ground point.

Wire the Remote connection to the auto start lead of your head unit, equalizer or power antenna.

About power fuses:

Pyle GearX Series amplifiers feature built-in fuse systems. These fuses protect both the amplifierand the electrical system in your vehicle from fault conditions. If you ever need to replace thefuse in your Pyle GearX Series amp, use a fuse of exactly the same type and rating. A differenttype or rating of fuse may result in damage or fire.

mountingYour new Pyle GearX Series amplifier comes complete with all required mounting hardware. When determining a suitable location in your vehicle for the amp, please rememberthat it is a high-power electronic device capable of generating high heat.

For this reason, always choose a location in your vehicle which has low vibration, adequate ventilation, a minimum of dust, and no moisture. Be sure tomount the amp in such a manner as to allow reasonable airflow over the cooling fins.

Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in eachof the mounting holes to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.

Before attempting to drill the mounting holes, take note of any wires, lines or other devices in your vehicle which may be located behind the mountingsurface! Then drill pilot holes in the mounting surface for the mounting screws and insert them. Tighten the screws securely.

The built-in protection circuitry in the Pyle GearXSeries amplifiers will disable the amplifier if it sensesan input overload, a speaker short circuit, or extremetemperature conditions.

When the protection circuit is activated by any ofthese conditions, the Protection LED will beilluminated.

If this occurs, carefully inspect the system todetermine the source of the problem.

• If the shutdown was a result of a thermal overloadcondition, allow the amplifier to cool down beforeattempting to restart it.

• If the shutdown was a result of an input overload,or speaker short circuit, be sure to correct thecondition before restarting.

The amplifier can be restarted by turning the remotepower OFF and then ON again.

No output.Confirm that all terminal strip connections are secure and tight.

Check both in-line and built-in fuses. Both the +12V and the Remote terminals must have +12v referenced to chassisground.

Confirm that the audio signal source (car radio, equalizer, etc.) is connected and is supplying output signal. Tocheck if the amp is supplying signal, unplug the cables from the signal source (but leave them plugged into theamp). Briefly tap the center pin of each of the disconnected RCA plugs with your finger. This should produce a noise(feedback) in your speakers.

Only one channel works.Confirm that all terminal strip connections are secure and tight.

Check the Balance control on the head unit (or other source) to verify that it is set to its midpoint.

If you are using the Low Level RCA input, reverse the input plugs at the amplifier (i.e., switch the L with the R). Ifthe channels which is silent switches to the other side, the problem is either in the head unit/other source or theconnecting cables.

Weak output.Readjust the Input Level Control(s) to better suit the input signal.

Noise in the audio.If the noise is a “whine” whose pitch follows the engine speed, confirm that the amplifier and any other signalsources (head unit, etc.) are properly grounded.

If the noise is a “clicking” or “popping” noise whose rate follows the engine speed, this usually means that thevehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service.

Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnectlights and other accessories.

If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobileaudio installer.

notesprecautionsDo not operate the amplifier when it is unmounted.Attach all audio system components securely withinthe automobile to prevent damage, especially in anaccident.

Do not mount this amplifier so that the wireconnections are unprotected, or in a pinchedcondition, or likely to be damaged by nearby objects.

Before making or breaking power connections inyour system, disconnect the vehicle battery. Confirmthat your head unit or other equipment is turned offwhile connecting the input jacks and speakerterminals.

If you need to replace the power fuse, do so onlywith a fuse identical to that supplied with the amplifier.Using a fuse of a different type or rating may resultin damage that isn’t covered in the manufacturer’swarranty.
