JFA X5 Bass Evo 5-Way Car Audio Crossover

Organize your car audio system into five signal paths

The JFA X5 Bass Evo is a five-way electronic crossover designed to help configure a multi-amplifier car audio installation. With four inputs, 12 output channels, and level control across the signal paths, it provides tools for matching frequency bands to compatible equipment.

Picture your next listening session after your installer has balanced the low, mid-low, mid-high, high, and flat paths. Adjustable bass boost and crossover filtering help tailor the setup around your speakers and amplifiers.

Key Benefits

• Five signal paths: LOW, MID LOW, MID HIGH, HIGH, and FLAT.
• Four input channels: Left and right main inputs plus left and right sub inputs.
• 12 output channels, described in the source as two mono (L+R) and 10 stereo (L/R) channels.
• Adjustable bass boost on the low path, from 0 to +14dB.
• Level control on all paths for system balancing.
• Subsonic filtering and fixed/variable crossover filters.

Compatibility and Installation

This crossover processes audio signals; it is not a power amplifier and does not directly drive speakers. Use it with compatible source equipment and external amplifiers.

Professional installation and tuning are recommended. Verify signal connections, power requirements, frequency settings, and output routing against the manufacturer's documentation. Adjust bass boost and band levels according to the connected speakers and amplifiers; filtering does not guarantee protection against damage from incorrect setup.

Bring five-way signal control to your next car audio build with the X5 Bass Evo.
