Connexions de cablejat
The Quantum QB2150 amplifier features direct-connect integrated terminals for power, ground, remote, and speaker outputs. Refer to the image below for a visual representation of the amplifier's layout.

- Connexió d'alimentació (+12 V): Connect a suitable gauge power cable (e.g., 8 AWG or 4 AWG depending on total system power) from the amplifier's +12V terminal directly to the positive terminal of the vehicle's battery. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Connexió a terra (GND): Connect a power cable of the same gauge as the +12V cable from the amplifier's GND terminal to a clean, unpainted metal point on the vehicle's chassis. Ensure a good electrical connection.
- Engegada remota (REM): Connect a small gauge wire (e.g., 18 AWG) from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire turns the ampengegueu i apagueu l'activador amb la unitat principal.
- Entrada RCA: Connecteu els cables RCA del pre-amp outputs of your head unit to the RCA input jacks on the ampmés viu.
- Sortida de l'altaveu: Connecteu els vostres altaveus al amplifier's speaker output terminals. For stereo operation, connect one speaker to each channel. For bridged mono operation, refer to the amplifier's specific bridging instructions (typically using the positive terminal of one channel and the negative terminal of the other). Ensure correct polarity.
- Instal·lació de fusibles: Insert the specified ATC 20 amp fuse into the amplifier's fuse holder.
Funcionament
Encesa inicial
- Després de fer i verificar totes les connexions, torneu a connectar el terminal negatiu de la bateria del vehicle.
- Engegueu la unitat principal. El amplifier should power on, indicated by an illuminated power LED.
- Comença amb el ampcontrol de guany del lificador ajustat al mínim.
- Play a familiar audio track at a moderate volume level on your head unit.
- Augmenta lentament el amplifier's gain control until the desired volume is achieved without distortion. Do not set the gain too high, as this can cause clipping and damage to speakers.
Ajust de la configuració
- Control de guany: Coincideix amb el ampsensibilitat d'entrada del lifter al volum de sortidatage of your head unit. Adjust for clean, undistorted sound.
- Bass Boost (45Hz, 0-12dB): Allows for an increase in bass output at 45Hz. Use sparingly to avoid distortion.
- Subsonic Filter (15-55Hz): (If applicable for specific configurations) Filters out extremely low frequencies that are inaudible and can waste amplifier power or damage subwoofers.
Manteniment
- Mantenir el ampMantingueu el llifador net i sense pols. Feu servir un drap suau i sec per netejar-lo.
- Assegureu-vos una ventilació adequada al voltant amplifier to prevent overheating. Do not block the heat sink fins.
- Comproveu periòdicament totes les connexions del cablejat per verificar si estan ben ajustades i si hi ha corrosió.
- Si el amplifier's protection circuit activates (indicated by a protection LED), turn off the system, identify and resolve the issue, then restart.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense energia / Sense so | Fusible fundit, mala connexió d'alimentació/terra, sense senyal remot. | Comproveu amplifier fuse, battery fuse, power and ground wires. Verify remote wire connection to head unit. |
| So distorsionat | Gain set too high, poor speaker connection, damaged speaker, low input signal. | Reduce gain. Check speaker wiring for shorts or loose connections. Inspect speakers for damage. Ensure head unit output is clean. |
| Ampsobreescalfament del lificador | Insufficient ventilation, impedance too low, prolonged high volume. | Assegureu-vos que el flux d'aire sigui adequat al voltant amplificador. Comproveu la impedància de l'altaveu. Reduïu el volum o permeteu amplificador per refredar. |
| LED de protecció encès | Short circuit in speaker wiring, amplifier overheating, DC offset. | Check all speaker wires for shorts to ground or each other. Allow amplifier to cool. Disconnect RCA inputs to check for DC offset from head unit. |
| Engine Noise / Whine | Poor ground connection, RCA cables too close to power wires, faulty RCA cables. | Improve ground connection. Reroute RCA cables away from power wires. Try different RCA cables. |
