Owner's Manual for VIBE Powerbox 100.4M Car Amplifier

Quick guide from the manual

This manual provides essential installation and operation instructions for the VIBE Powerbox 100.4M amplifier. Key safety requirements include mounting the unit in a dry location on a solid surface, ensuring adequate airflow (at least two inches around the casing), and never mounting the unit upside down to prevent overheating. Always disconnect the fuse until the installation is complete.

Mounting Guidelines

The amplifier is designed for a swift installation routine. Ensure the chosen location is dry and solid. Proper ventilation is critical; ensure there is at least two inches of space around the exterior of the casing to allow for effective cooling. Do not mount the amplifier upside down.

Power Connections

Proper power delivery is essential for performance:

• Use at least 8 gauge cable for both power and ground connections.
• The power cable must be taken directly from the battery.
• Install a fuse or circuit breaker inline with the power cable, no further than 18 inches from the battery.
• The ground cable should be connected directly to the vehicle chassis at a bare metal point. Keep the cable length to an absolute minimum.
• Do not use the vehicle's seatbelt anchor point for the ground connection.

Inputs and Auto Turn On

The amplifier supports both low-level (RCA) and high-level (speaker) inputs. Do not connect both input types simultaneously. The PowerBox features an 'Autosense' circuit, which allows the amplifier to switch on and off automatically when using high-level inputs, eliminating the need for a remote turn-on wire. If using low-level (RCA) inputs, a remote turn-on wire from the head unit is required.

Terminals and Connections

The amplifier features various controls for fine-tuning audio:

• Gain Control: Used to match the input signal of the source to the amplifier channels.
• Crossover Mode Select: Choose between Full Range (FR), High Pass Filter (HPF), or Low Pass Filter (LPF).
• Filter Controls: High pass filter is adjustable between 100Hz and 500Hz; low pass filter is adjustable between 40Hz and 4kHz.
• Input Mode Switch: Selects between 2 or 4 channel signal input.
• Power/Protect LED: A green light indicates normal operation, while a red light indicates the amplifier is in protection mode.

Wiring Configurations

The amplifier supports different wiring setups depending on your speaker configuration:

• 4 Channel Configuration: Allows for 2Ω minimum impedance per channel.
• Bridged Wiring Configuration: Allows for 4Ω minimum impedance for bridged channels.
