Metra IBLOC04 4-Channel Adjustable Line Output Converter 60W

The Metra Install Bay IBLOC04 is a 4-channel adjustable line output converter (LOC) that bridges the gap between factory head units and aftermarket amplifiers. It converts high-level speaker signals into low-level RCA preamp signals, making it easy to integrate an external amplifier into any existing audio system without replacing the factory radio.

Key Features:

• 4-Channel design handles all four speaker channels simultaneously
• 60-watt input power handling per channel for compatibility with a wide range of factory and aftermarket head units
• Fully adjustable dual output level controls allow precise tuning of the RCA output signal
• Transformer-based design isolates ground loops to minimize noise and interference
• Wired speaker-level inputs convert to 2 RCA female outputs for clean amplifier connection

The IBLOC04 is an essential accessory for anyone adding an aftermarket amplifier or subwoofer to a factory audio system. Simply connect the converter to the existing speaker wires behind the head unit, adjust the output levels to match your amplifier's sensitivity, and enjoy clean, low-level RCA signal delivery to your amp.
