5.2. Konexioak amaituview
The amplifier features various input and output terminals for power, signal, and speaker connections. Refer to the images below for a visual guide.

Deskribapena: This image displays the Audison SR 4.300 amplifier from a front-side perspective. Visible are the Audison logo, model number, and various input/output terminals including RCA inputs, speaker inputs, and power connections. The ribbed heat sink design is also prominent.

Deskribapena: Irudi honek goitik beherako irudia eskaintzen du view of the Audison SR 4.300 amplifier. The control panel is clearly visible, featuring switches and potentiometers for channel selection, input mode, filter settings (LP/HP/BP), and gain adjustments for channels A and B. Power and speaker terminals are also visible along the edges.

Deskribapena: This close-up image focuses on the input and output section of the Audison SR 4.300 amplifier. It shows the RCA input jacks (MONO IN, IN A, IN B), speaker-level inputs, and pre-out connections. The power and remote turn-on terminals are also visible, along with the speaker output terminals.
5.3. Konexio elektrikoak
- Connect the main power cable (positive +12V) to the amplifier's +12V terminal. Ensure an appropriate fuse (1 x 30A) is installed close to the vehicle's battery.
- Konektatu lurreko kablea amplifier's GND terminal and to a clean, unpainted metal point on the vehicle chassis.
- Connect the remote turn-on wire from your head unit to the amplifier's REM IN terminal. If using Speaker-In inputs with an OEM head unit, the ART (Automatic Remote Turn-On/Off) feature can be utilized, eliminating the need for a separate remote wire.
5.4. Seinale sarrerak
- RCA sarrerak: For aftermarket head units, connect RCA cables from the head unit's pre-outs to the amplifier's RCA-In terminals (IN A, IN B).
- Bozgorailu-mailako sarrerak: For OEM head units without RCA outputs, connect the speaker wires directly to the amplifier's Speaker-In terminals. The built-in USS (Universal Speakers Simulator) ensures compatibility.
5.5. Bozgorailuaren irteerak
Konektatu zure bozgorailuak amplifier's speaker output terminals (AL, AR, BL, BR). Ensure correct polarity (+/-) for each speaker. The amplifier supports 2 Ohm stable operation.
6. Funtzionamendu-argibideak
Once installed, configure the amplifier settings using the controls on the top panel (refer to Figure 2).
