Product Usage Instructions

Before installing the amplifier, check the polarities of the speakers and ensure that the amplifier is compatible with the power requirements of your vehicle’s system. If you have any questions, contact the store where the purchase or installation was made or contact Stetsom’s customer service.

Audio Input

The amplifier has two input options – RCA and High Input connections. Use the High Input connection when your radio or player doesn’t have RCA outputs. The High Input connector has a stereo signal (L + R) identified on the product. Check the radio or player amplified output signals before making connections. For remote amplifier activation, use the REMOTE IN or REM connection. The RCA connection is a dual RCA connection with a stereo input (L+R) identified on the product. Connect to the radio or player outputs via quality shielded RCA cables to prevent unwanted noise. Using both the RCA input and High Input connections at the same time can cause unwanted noise and amplifier problems.

Using REMOTE IN (High Input)

The amplifier’s REMOTE-IN feature can be turned on in three different ways, depending on your vehicle’s system. If your radio has a remote (REM) output, connect it directly to the REM IN (green wire) of the High Input output for automatic amplifier activation.

Audio Controls

The amplifier has a gain control that allows you to adjust the signal level that will be sent to the speakers. Use this control to equalize the music volume played through the speakers. The amplifier also has subsonic and low pass filters, and bass boost options that can be adjusted according to your preferences.

Introduction

Audio input

HIGH INPUT CONNECTION: Use the connection when the radio/player doesn’t have RCA outputs. The connector has a stereo signal (L + R) identified on the product. Check the radio/player amplified output signals before making connections. For remote amplifier activation, use the REMOTE IN or REM connection.

RCA CONNECTION: Dual RCA connection with a stereo input (L+R) identified on the product. Connect to radio/player outputs via quality shielded RCA cables to prevent unwanted noise.

Using the RCA input and HIGH INPUT connections at the same time can cause unwanted noise and amplifier problems.

Using REMOTE IN (HIGH INPUT)
The amplifier’s REMOTE-IN feature can be turned on in three different ways, depending on your vehicle’s system.

REDECAN: This system has timings that can cause PUFF in the audio system. To minimize this happening in vehicles with this system, we recommend installing the REMOTE IN (green) wire to the ACC signal.

AUTO TURN ON: Connect the REMOTE IN (green) wire to any of your radio’s audio outputs. The amplifier will detect the presence of audio and turn it on automatically.

MANUAL OPERATION: Use a switch or button between the REMOTE IN connection (green wire) and the positive 12V battery supply for the manual operation of the amplifier.

If your radio has a remote (REM) output, connect it directly to the REM IN (green wire) of the HIGH INPUT output for automatic amplifier activation.

Audio controls

• GAIN: Allows you to adjust the signal level that will be sent to the speakers. Use this control to equalize the music volume played through the speakers.
• SUBSONIC FILTER: Variable control that allows you to adjust the initial frequency cut-off between 5Hz to 35Hz that will be reproduced by the amplifier.
• LOW PASS FILTER: Variable control that allows you to adjust the final frequency cut-off between 35Hz to 250Hz that will be reproduced by the amplifier.
• BASS BOOST:
• BOOST: Variable control for bass boost from 0dB to +18dB.
• FREQ: Variable control for BASS booster actuation from 35 Hz to 60 Hz.
• COOLER: Its operation optimizes the amplifier’s ventilation. Make the installation in a ventilated place, without obstruction in the air inlets and outlets.

Speakers output

• SPEAKERS CONNECTOR: MONO audio outputs for connecting speakers. Check the polarity of the speakers and the minimum impedance supported by the amplifier before carrying out the installation.

Power supply

• POSITIVE CONNECTOR: Connect to the battery’s positive terminal via a cable of at least 9 AWG with a fuse (20A) as close to the battery as possible.
• CONNECTOR FOR REMOTE ACTIVATION (REM): Allows automatic activation of the amplifier when turning on the radio/player. Connect to the REMOTE output of the radio/player via a minimum 18 AWG cable.
• NEGATIVE CONNECTOR: Connect to the negative battery terminal via a minimum 9 AWG cable.

Indicators LED

• POWER (Blue LED): Indicates the amplifier is operating when lit.
• PROT (Red LED): Indicates that the amplifier detected faults and entered protection mode. Check the possible failure and turn the amplifier back on.

Smart protection system
When the protection system is active, the amplifier will turn off and the PROT LED (RED)will light up. Turn off the amplifier to correct the indicated fault and turn it on again.

• Diagnostic: Short circuit or output overload.
• Solution: Check that the speaker cables are well insulated and that the output impedance doesn’t exceed that supported by the amplifier.

Troubleshooting

THE AMPLIFIER DOESN’T TURN ON

• Verify that the cables are connected correctly. Make sure all connections have electrical and mechanical contact.
• Fuses or circuit breakers may be defective or blown. Check the condition of the circuit breakers and if it is compatible with the equipment consumption.
• Verify that the battery charge is sufficient for the operation of the product

NO SOUND

The cables of the speakers or connections may not be connected correctly or are defective.

PROT LED ON

Check for shorted speakers or cables, and check speakers, cables, and connections.

SOUND DISTORTIONS

• Speakers may be overloaded or defective, turn down and re-adjust the level. This setting can be adjusted as follows:
• On the radio/player, put any musical signal and set the volume to 80% of the maximum (if the maximum volume of the radio/player is 45 (100%), set it to 36 (80%).
• On the amplifier, with the GAIN control at minimum, gradually increase it until you hear distortion in the speakers. Slowly return the GAIN until you notice that there is no more distortion in the audio.

LACK OF BASS

The cables of the speakers may be reversed. (out-of-phase speakers).

NOISE AND FAILURE IN SOUND

• Verify that the installation is not close to the original vehicle wiring as they may cause interference and noise in the audio signal.
• Make a separate power connection to the sound system. Use a fuse/ circuit breaker as close to the battery as possible for protection.
• Make a good grounding of the amplifier. To do this, remove the paint from the vehicle chassis at the desired point. Screw the wire using a ground terminal. To protect from oxidation, isolate with paint.
• Do not loop the ground. Avoid using multiple grounds. If possible, use a star connection, in which all the grounds run from a single point.
• Any updates made in this manual will be available for customers to consult without any charge on the brand’s site.
• It is recommended that the updated manual be consulted whenever needed.
