5. Opsætning og installation
Korrekt installation er afgørende for optimal ydeevne og sikkerhed. Hvis du er usikker på nogle trin, skal du kontakte en professionel installatør.
5.1 Monteringssted
- Choose a location that provides adequate ventilation for the amplivligere.
- Ensure the mounting surface is solid and secure.
- Avoid areas prone to excessive vibration, heat, moisture, or dust.
- Allow sufficient space around the amplifier for wiring connections and adjustments.
5.2 Ledningsforbindelser
Refer to the diagrams below for proper wiring.

Billede 4: Bund view af amplifier showing power, ground, remote, and speaker terminals.
- Strømtilslutning (+12V): Connect a fused power cable (minimum 8 AWG recommended) directly from the positive terminal of the vehicle's battery to the +12V terminal on the amplifier. Install the fuse holder within 18 inches (45 cm) of the battery.
- Jordforbindelse (GND): Connect a ground cable (minimum 8 AWG recommended) from the GND terminal on the ampFastgør sikringen til en ren, umalet metaloverflade på køretøjets chassis. Sørg for en solid elektrisk forbindelse.
- Fjerntænding (REM): Tilslut en fjernbetjeningsledning fra din hovedenheds fjernbetjeningsudgang til REM-terminalen på ampDenne ledning signalerer amplifter til at tænde og slukke med dit lydsystem.
- RCA-indgang: Connect RCA cables from your head unit's pre-out to the INPUT L and R RCA jacks on the amplivligere.
- Højttaler output: Connect your speakers to the SPK OUT terminals. Ensure correct polarity (+ to + and - to -). For bridged operation, refer to the specific bridging instructions in the full manual (not provided here, but implied).
6. Betjeningsvejledning
The VAD8402v2 amplifier features several controls to fine-tune your audio system.

6.1 Få kontrol
GAIN-kontrollen matcher amplifier's input sensitivity to the output of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. Do not use the gain control as a volume knob.
6.2 Crossover (X-OVER)
The X-OVER switch allows you to select the type of filter:
- HPF (Højpasfilter): Tillader frekvenser over setpunktet at passere igennem. Nyttig til full-range højttalere for at forhindre lav basforvrængning.
- LPF (lavpasfilter): Tillader frekvenser under sætpunktet at passere igennem. Bruges typisk til subwoofere.
- FULD: Disables the crossover, allowing all frequencies to pass.
Adjust the HPF and LPF frequency knobs (40 - 500 Hz) according to your speaker specifications and desired sound.
6.3 basforstærkning
The BASS BOOST control allows you to increase the bass output at a specific frequency. Use this feature sparingly to avoid distortion and potential speaker damage.
6.4 Fjernbetjening til bas
Connect the remote bass knob to the "REMOTE" port on the amplifier. This allows for convenient adjustment of the bass level from your listening position.
7. Vedligeholdelse
- Behold ampRengøring af apparatet er ren og fri for støv. Brug en blød, tør klud til rengøring.
- Sørg for, at alle ledningsforbindelser er sikre. Kontroller regelmæssigt for løse forbindelser.
- Bloker ikke amplifier's cooling fins or ventilation areas.
- Hvis amplifier becomes excessively hot, check for proper ventilation and speaker impedance.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm / Amplifer tænder ikke | Sprunget sikring, løs strøm-/stel-/fjernbetjeningsledning, defekt fjernbetjeningsstartsignal. | Check fuse, verify all power connections, test remote wire for +12V when head unit is on. |
| Ingen lydudgang | Løse RCA-kabler, forkert forstærkningsindstilling, højttalerledninger frakoblet, amplifer i beskyttelsestilstand. | Check RCA connections, adjust gain, verify speaker wiring, check protection indicator. |
| Forvrænget lyd | Gain set too high, improper crossover settings, faulty speakers, low input voltage. | Reduce gain, adjust crossover, check speaker condition, ensure stable power supply. |
| AmpOverophedning af væske | Insufficient ventilation, low speaker impedance, prolonged high-volume operation. | Improve ventilation, verify speaker impedance (should be 2-4 ohms per channel), reduce volume. |
