4. Configuració i instal·lació
Una instal·lació correcta és crucial per al rendiment i la seguretat del vostre amplificador. Segueix aquests passos amb atenció.
4.1 Ubicació de muntatge
Choose a mounting location that provides adequate ventilation, is protected from moisture, and is secure. Avoid mounting on carpet or directly to metal surfaces without proper insulation.
Figura 4.1: Example of a T400X4ad amplifier installed in a vehicle, demonstrating a secure and accessible mounting location.
4.2 Connexions de cablejat
Ensure all connections are tight and secure to prevent power loss or short circuits.
4.2.1 Power and Ground Connections
- B+ (Power): Connect directly to the positive terminal of the vehicle's battery using an appropriate gauge power wire and an in-line fuse within 18 inches of the battery.
- GND (terra): Connect to a clean, bare metal chassis ground point in the vehicle. The ground wire should be the same gauge as the power wire and as short as possible.
- REM (encesa remota): Connecteu-lo a la sortida d'encesa remota de la unitat principal. Aquest cable indica el amplificador per encendre i apagar amb la unitat principal.
Figure 4.2: Rear panel connections for power (B+), ground (GND), remote (REM), and speaker outputs (Front and Rear Speakers).
4.2.2 Connexions d'entrada
The T400X4ad supports both low-level (RCA) and high-level (speaker wire) inputs.
- Entrada de baix nivell: Connecteu els cables RCA des del pre-emissor de la unitat principalamp sortides al amplifier's FRONT and REAR input jacks.
- Entrada d'alt nivell: If your head unit does not have RCA outputs, use the included high-level input harness to connect directly to your head unit's speaker outputs. The amplifier features auto turn-on when using high-level inputs.

4.2.3 Connexions d'altaveus
Connecteu els vostres altaveus al amplifier's speaker output terminals. Ensure correct polarity (+ to + and - to -) for each speaker. The amplifier can be configured for 4-channel stereo or 2-channel bridged operation.
- Estèreo de 4 canals: Connect one speaker to each of the four output channels.
- Pont de 2 canals: For higher power output to two speakers (e.g., subwoofers), bridge the front channels and the rear channels. Refer to the wiring diagram on the amplificador per a connexions de pont correctes.
5. Instruccions de funcionament
Un cop instal·lat, ajusteu el ampConfiguració del lifer per a un rendiment d'àudio òptim.
5.1 Ajust del nivell d'entrada
The input level (gain) controls match the amplifier's input sensitivity to the output of your head unit. This is not a volume control.
- Gireu el amplifier's input level controls to their minimum (counter-clockwise) position.
- Ajusteu el volum de la unitat principal al 75% aproximadament del seu màxim.
- Augmenta lentament el amplifier's input level control until you hear distortion or the CLEAN clip indicator illuminates. Then, back off slightly until the distortion or clip indicator disappears.
5.2 Crossover Adjustment
The T400X4ad features a 12dB/octave Butterworth crossover for both front and rear channels, allowing you to filter frequencies sent to your speakers.
- Full Range (AP): Passes all frequencies to the speakers.
- High Pass (HP): Allows frequencies above the set point to pass, typically used for full-range speakers to protect them from low bass.
- Low Pass (LP): Allows frequencies below the set point to pass, typically used for subwoofers.
Adjust the frequency knob (FREQ) to the desired crossover point based on your speaker's specifications.
5.3 Punch EQ Adjustment
The on-board Punch EQ provides a bass boost at 45Hz. Use this feature to enhance bass response if desired.
- Start with the EQ control at its minimum position.
- Gradually increase the EQ level to achieve the desired bass enhancement. Avoid excessive boost, which can lead to distortion or speaker damage.
6. Manteniment
The Rockford Fosgate T400X4ad amplifier requires minimal maintenance.
- Neteja: Netegeu periòdicament el ampl'exterior del purificador amb un drap suau i sec. No utilitzeu productes químics agressius ni netejadors abrasius.
- Connexions: Occasionally check all wiring connections to ensure they remain tight and free from corrosion.
- Ventilació: Assegureu-vos que el ampLes aletes de refrigeració del lificador estan lliures de pols i deixalles per mantenir una dissipació adequada de la calor.
