CT Sounds 2-Channel Line-Out Converter with BassLift

The CT Sounds CT-LC2 is a 2-channel premium line-out converter that turns high-level speaker outputs into clean RCA signals and restores low-end with BassLift technology.

If you want to add an aftermarket amplifier or subwoofer to a factory stereo without RCA outputs, the CT-LC2 offers a compact, installer-friendly solution. It converts speaker-level signals to low-level RCA outputs while providing a dedicated low-pass bass output and a BassLift circuit to compensate for factory bass roll-off. The unit ships with a detailed 34-page manual to guide wiring and tuning for a wide range of vehicles and OEM head units.

How does the CT-LC2 convert speaker signals for aftermarket amplifiers?

The CT-LC2 accepts high-level signals from factory speaker wires and converts them into stable low-level RCA outputs suitable for amplifiers. Conversion is engineered to preserve tonal balance and minimize noise so your amp receives a clean input signal.

• 2-channel conversion for left and right speaker signals
• Full-range main RCA outputs for front/rear amp channels
• Low-pass bass RCA output for subwoofer connection
• High-to-low level circuitry designed to reduce distortion and hum

What is BassLift and when should I use it?

BassLift is a compensation circuit that restores low-frequency content often removed by factory head unit processing. Use it when the stock system sounds thin or when adding a subwoofer to reproduce deeper bass that the factory setup suppresses.

• Restores bass lost from factory roll-off and signal processing
• Improves subwoofer punch and low-end clarity
• Adjustable to match different head unit output characteristics
• Helps maintain balanced tones when driving aftermarket amps

Can I run both full-range speakers and a dedicated subwoofer at the same time?

Yes — the CT-LC2 provides a full-range main output for speakers and a separate low-pass output tuned for subwoofers. This lets you feed an amplifier for your speakers and another for the sub without extra signal splitters, simplifying installation and preserving channel integrity.

• Full-range RCA outputs for front/rear speaker amps
• Low-pass RCA output dedicated to subwoofer amplifier
• Maintains proper crossover separation between speakers and sub
• Ideal for systems upgrading both speakers and bass reproduction

How simple is installation and what support is included?

Installation is straightforward for installers familiar with car audio wiring: connect speaker wires to the CT-LC2, run RCA cables to amplifiers, and adjust BassLift as needed. A comprehensive 34-page manual walks through wiring diagrams, adjustment tips, and troubleshooting steps to speed up installation and reduce uncertainty.

• Includes step-by-step 34-page product manual
• Clear wiring diagrams and mounting suggestions
• Compact enclosure fits behind dash or near factory amp locations
• Works with most factory and aftermarket head units

Who is this for: The CT Sounds CT-LC2 is intended for car audio enthusiasts and installers who need to add aftermarket amplifiers or subwoofers to vehicles with factory head units lacking RCA outputs—or whose OEM systems roll off bass. It suits anyone wanting clean RCA-level signals, a dedicated sub output, and a simple way to recover lost low frequencies without replacing the factory stereo.
