Read Before Installation
- Carefully read and understand all instructions before attempting installation.
- For safety, disconnect the negative battery terminal before beginning installation.
- For easier assembly, run all wires prior to mounting speakers. Have tools ready: drill, Allen keys, crimpers, soldering iron, wire strippers, heat shrink tubing, etc.
- Use high-quality connectors for a reliable installation and to minimize signal or power loss.
- Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines, or electrical wiring. On boats, take care not to cut or drill through the main hull.
- Never place cables near fuel lines or power sources. Running wires inside the vehicle or hull area provides the best protection.
- Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect wires routed through metal, especially the firewall.
Installation
- Determine speaker mounting location. Ensure adequate space for even mounting and sufficient depth. Mount only on a flat surface. Use caution on panels with urethane foam.
- Refer to the specification chart for the proper hole diameter.
- Mark screw locations and drill holes with a 1/8" bit.
- Feed speaker wires through the cutout and connect to speaker terminals, observing proper polarity (positive terminal indicated by "+").
- Fit the speaker and mount using six (6) screws.
- Tighten screws until the speaker is snug.
LED Connections
There are two options for LED connections:
Option 1: With LED Control Module (LED-BTC)
Connect as shown in the following diagram description:
Diagram Description: The diagram illustrates the wiring for the LED-BTC module. It shows the LED-BTC module connected to a 12V battery (positive and negative terminals). The speaker's positive and negative wires are connected to the speaker output terminals on the LED-BTC module. Additionally, various colored wires (Red, Green, Blue, White, Grey) are shown connecting from the speaker to the LED-BTC module, corresponding to different LED color functions.
Wire Color Key:
- Blue LED (-) / LED Azul (-)
- Red LED (-) / LED Rojo (-)
- Green LED (-) / LED Verde (-)
- Black 12V DC (+) / 12 V DC Negro (+)
- White Speaker (+) / Altavoz Blanco (+)
- Grey Speaker (-) / Altavoz Gris (-)
Option 2: Without LED Control Module (LED-BTC)
Connect as shown in the following procedure:
- Black wire "BK" connected to Battery Positive (+) 12V.
- White Color Light "R", "B", and "G" connected to Battery Negative (-).
- Green Color Light "G" connected to Battery Negative (-).
- Red Color Light "R" connected to Battery Negative (-).
- Blue Color Light "B" connected to Battery Negative (-).
- Purple Color Light "R" and "B" connected to Battery Negative (-).
- Yellow Color Light "R" and "G" connected to Battery Negative (-).
- Cyan Color Light "B" and "G" connected to Battery Negative (-).
Example of Green Light Connection:
Diagram Description: This section provides wiring instructions without the LED-BTC module and an example for green light connection. The diagram shows the speaker's positive wire (White) connected to the vehicle's 12V positive terminal (Black wire from speaker). The speaker's negative wire (Grey) is connected to the vehicle's negative terminal. For specific LED colors, wires like Green are shown connecting directly to the battery negative terminal to activate that color.
