STEG GLORIA 120.2 Car Audio Amplifier
250,00 €
The STEG GLORIA 120.2 is a two-channel car amplifier for a speaker system or subwoofer. Switchable stereo and mono operation provides a choice between two separate channels and one bridged channel. Its compact 109 × 40 × 95 mm enclosure simplifies installation where space is limited. Stereo output reaches 2 × 130 W RMS at 2 ohms, while bridged mono output is 250 W RMS at 4 ohms.
The STEG GLORIA 120.2 amplifier is a compact two-channel car audio amplifier designed for systems where installation space is limited. This Class D amplifier can operate in either stereo or mono mode, allowing one unit to power a speaker system or a subwoofer.
Choosing between stereo and mono operation
In stereo mode, the amplifier can power a passive component system or a pair of front or rear speakers. It can also be used with two subwoofers. With a 4-ohm load, the specified output is 100 W RMS per channel. At 2 ohms, the specified output increases to 130 W RMS per channel.
Mono mode is intended for powering a single subwoofer. When the channels are bridged, the amplifier provides a specified output of 250 W RMS into 4 ohms. The minimum supported load in mono mode is 2 ohms, but a mono power rating at 2 ohms is not provided.
Before connecting a subwoofer, calculate its final impedance carefully. Series or parallel wiring of a dual-voice-coil driver changes the total load presented to the amplifier. The resulting impedance must not fall below 2 ohms when the amplifier is used in mono mode.
Setting the input sensitivity
The input sensitivity range is 0.2 to 5 V RMS. This adjustment allows the amplifier to be matched to the output signal level of the connected audio source. Input sensitivity is not an additional volume control.
Begin the adjustment with the gain set to its lowest position. Set the source unit to a normally high listening level, then increase the amplifier gain gradually. Stop before audible distortion appears. This approach matches the signal levels of the source and amplifier while helping you avoid excessive gain.
Installation where space is limited
The 109 × 40 × 95 mm enclosure is suitable for locations where a conventional amplifier would be difficult to accommodate. Its compact format makes it a practical option when planning a concealed car audio installation. A weight of 0.300 kg also gives the installer more flexibility when choosing a secure mounting position.
Do not consider the enclosure dimensions alone when planning the installation. Allow sufficient room for the cables, their required bend radius and air circulation around the unit. Avoid covering the amplifier with trim panels in a way that completely prevents air from moving around the enclosure.

FAQ
When should I use stereo mode?
Choose stereo mode when you need two separate channels, such as for a front or rear speaker system. When powering a passive component speaker system, its passive crossover must divide the appropriate frequency ranges between the drivers.
Can I connect a 2-ohm subwoofer?
The minimum supported load in mono mode is 2 ohms. However, the stated 250 W RMS output applies to a 4-ohm load and must not be treated as a 2-ohm power rating.
How should I set the input sensitivity?
Match it to the output level of the audio source you are using. Start with a low gain setting and increase it gradually while listening for any audible distortion.
Is the amplifier suitable for concealed installation?
Its compact dimensions make a concealed mounting position worth considering. You must still leave enough room for cable routing and air circulation around the enclosure.
Can it power component speakers in a car?
Yes. Stereo mode is also intended for passive component systems. Check the impedance of the speaker system and the RMS power required by each channel before making the connection.
