Sikkerhedsoplysninger
- Frakobl altid bilens negative batteripol, inden du påbegynder elektrisk arbejde.
- Ensure proper grounding to the vehicle chassis.
- Brug passende ledninger til strøm-, jord- og højttalertilslutninger.
- Undgå at montere amplifier in areas exposed to excessive heat, moisture, or vibration.
- Kontakt en professionel installatør, hvis du er usikker på nogen del af installationsprocessen.
2. Opsætning og installation
2.1 Udpakning
Fjern forsigtigt amplifier from its packaging. Inspect for any signs of damage. If damage is present, contact your dealer immediately.
2.2 Monteringssted
Choose a mounting location that provides adequate ventilation for the amplifier. Avoid enclosed spaces that can trap heat. Ensure the location is secure and protected from moisture. Common locations include under seats, in the trunk, or behind panels.
2.3 Ledningsforbindelser
Proper wiring is crucial for performance and safety. Refer to the following guidelines for connecting power, ground, remote, input, and speaker wires.
Strøm- og jordforbindelser

- B+ (Power): Connect this terminal directly to the positive (+) terminal of the vehicle's battery using a fuse holder within 18 inches of the battery. Use appropriate gauge wire (e.g., 8 AWG for typical installations).
- GND (jord): Connect this terminal to a clean, bare metal point on the vehicle's chassis. Ensure a solid electrical connection. The ground wire should be the same gauge as the power wire and as short as possible.
- REM (fjerntænding): Connect this terminal to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with your stereo.
Indgangsforbindelser

- RCA Inputs (CH1, CH2, CH3, CH4): Connect these to the RCA pre-amp outputs of your head unit. Ensure correct channel matching (e.g., Front Left to CH1, Front Right to CH2, Rear Left to CH3, Rear Right to CH4).
- REM/DC/AUDIO Switch: This switch determines how the amplifner tænder.
- REM: Uses the remote turn-on wire from the head unit.
- DC: Detects a DC offset on the speaker-level inputs (for head units without a remote output).
- LYD: Detects an audio signal on the speaker-level inputs.
Forbindelser til højttalerudgang
Connect your speakers to the designated speaker terminals. The PRX500.4V2 is a 4-channel amplifier, allowing for various speaker configurations. Ensure correct polarity (+ to + and - to -) for all speakers.
- Standard 4-Channel: Connect one speaker to each channel output.
- Brokoblet tilstand: De amplifier can be bridged to provide more power to fewer channels (e.g., 2-channel operation for subwoofers). Refer to the amplifier's terminal markings for correct bridging connections.
3. Betjening af Amplivligere
3.1 Indledende opstart
After all connections are made, reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on, indicated by an illuminated logo or status LED.
3.2 Betjening og justeringer
Billede 3.1: Vinklet view of the Memphis Audio PRX500.4V2 amplifier, highlighting the input side with RCA connections and control switches.
- INPUT LEVEL (Gain Control): Denne kontrol passer til ampadapterens inputfølsomhed i forhold til udgangsniveauet på din hovedenhed. Start med forstærkningen indstillet til minimum. Afspil et velkendt nummer ved ca. 75 % af din hovedenheds maksimale lydstyrke. Øg langsomt amplifier's gain until you hear distortion, then back it off slightly.
- 2CH/4CH Switch: This switch determines whether the amplifier uses 2 or 4 input channels.
- 2CH: If your head unit only has 2 RCA outputs, this setting will feed the signal to all 4 amplifier kanaler.
- 4CH: For head units with 4 RCA outputs, allowing independent control of front and rear channels.
- LOW/HI (Crossover Switch): This switch activates the built-in crossover.
- LAV: Activates a low-pass filter, allowing only low frequencies to pass through (suitable for subwoofers).
- Hej: Activates a high-pass filter, allowing only high frequencies to pass through (suitable for full-range or component speakers).
4. Vedligeholdelse
Memphis Audio PRX500.4V2 ampLifier kræver minimal vedligeholdelse for at sikre langsigtet ydeevne.
- Rensning: Tør regelmæssigt af ampRengør ydersiden af apparatet med en blød, tør klud for at fjerne støv og snavs. Brug ikke skrappe kemikalier eller slibende rengøringsmidler.
- Ventilation: Sørg for, at ampKøleribberne er fri for blokeringer for at muliggøre korrekt varmeafledning.
- Forbindelser: Kontrollér lejlighedsvis alle ledningsforbindelser for tæthed og korrosion. Løse forbindelser kan føre til dårlig ydeevne eller skader.
5. Fejlfinding
Hvis du oplever problemer med din amplifier, refer to the following table for common problems and solutions.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ampkøleren tænder ikke | Ingen strøm, jord eller fjernsignal; Sprunget sikring | Kontroller strøm-, jord- og fjernkabelforbindelser. Kontroller sikringen ved batteriet og på amplifier. Check REM/DC/AUDIO switch setting. |
| Ingen lydudgang | Intet indgangssignal; Højttalerledninger frakoblet; Amplifter i beskyttet tilstand | Check RCA input connections. Verify speaker wire connections. Check amplifier status LED (if red, troubleshoot protect mode). Adjust gain. |
| Forvrænget lyd | Gain set too high; Improper crossover settings; Poor ground connection | Reduce gain setting. Adjust crossover switch. Ensure solid ground connection. Check speaker impedance. |
| Ampkøleren overophedes | Insufficient ventilation; Low impedance load; Prolonged high output | Sørg for god luftgennemstrømning omkring amplifier. Check speaker impedance (do not go below 2-Ohm per channel or 4-Ohm bridged). Reduce volume or gain. |
If the problem persists after attempting these solutions, contact Memphis Audio customer support or a qualified installer.
