Kicker 46KISLOC2 K-Series Stereo Line-Output Converter
The KISLOC2 converts a vehicle’s speaker signal to both an RCA output and a remote 12-volt wire for amplifier turn-on. It supports up to 55 watts of input and provides a neutral sonic profile, preserving highs and lows. This makes it suitable for enthusiasts who want clean sound with minimal coloration and reliable remote control integration. Best for installations where the user needs a compact converter with a dedicated remote output for seamless amplifier control.
Best for: Car owners adding a verified, low-noise line-out to an aftermarket amp. Caution: Ensure your factory head unit can drive the input level without distortion at high volumes.
Scosche LOC80 Line Output Converter
The LOC80 offers versatile compatibility and is designed to convert speaker-level signals to RCA line-level signals for aftermarket amplifiers. Its broad compatibility makes it a go-to for many car audio systems, and it’s optimized to preserve sound quality when boosting your system. Best for: Installers upgrading a wide range of vehicles who want straightforward integration into a subwoofer setup. Caution: Some setups may require additional wiring or adapters for perfect timing alignment.
BOSS Audio Systems B65N High Level to RCA Converter
The B65N focuses on reducing unwanted alternator noise while converting high-level signals to RCA. It includes input sensitivity adjustment to tailor levels to your amplifier. Best for: Drivers facing electrical noise issues in the vehicle who still want a simple, effective conversion. Caution: Performance may vary with very high-output factory radios; test for noise before final installation.
NuIth Car Audio: 2-Channel High to Low RCA Converter
The NuIth converter enables adding a 2-channel or mono amplifier or subwoofer to a stock or aftermarket stereo. It provides a level-gain adjustment to help dial in bass without pulling over, which is beneficial for on-the-road fine-tuning. Best for: Users who want straightforward gain control while expanding their system. Caution: The gain adjustment should be used gradually to avoid distortion at higher volumes.
Skar Audio SKAR2CH-LOC 2-Channel Converter
The SKAR2CH-LOC is compatible with OEM and aftermarket radios and accepts up to 55 watts input, claiming a flat 20 Hz–20 kHz range at all volume levels. This makes it a strong choice for listeners seeking consistent performance across the audible spectrum. Best for: Users wanting a reliable, low-profile converter that maintains a broad frequency response. Caution: Some factory systems may require additional harnesses for optimal integration.
Buying Guide
Key considerations for choosing a high-level to RCA converter include input power handling, output options, and installation simplicity. The best choice aligns with the vehicle’s audio goals and the amplifier’s requirements. Consider the following:
- Voltage and power handling: Look for converters that handle the same or higher input wattage as your factory system to prevent clipping.
- Remote turn-on capability: A dedicated remote output helps the amplifier switch on cleanly with the head unit.
- Noise rejection: Ground loop isolation and noise mitigation reduce alternator and engine whine.
- Compatibility: Verify compatibility with OEM, aftermarket, and smart radios to ensure seamless integration.
- Gain control: Adjustable gain helps tailor bass and overall output without distortion.
- Form factor and wiring: Smaller footprints simplify dash installs; plan for wire routing and harnessing.
Which converter should you choose?
Choose this if you want robust remote options and strong input handling (Kicker 46KISLOC2). Opt for versatile installation and broad compatibility (Scosche LOC80 or LOC2SL) if you aim to match multiple head units. For drivers concerned about electrical noise, the BOSS B65N is a sensible pick. If gain control during on-road driving is a priority, NuIth offers practical adjustment features. Finally, for a trusted, solid-frequency performance with OEM and aftermarket radios, the Skar SKAR2CH-LOC stands as a reliable choice.
Installation tips
- Plan wire routing to avoid heat sources and moving parts.
- Test for noise at various engine speeds before final mounting.
- Label connections to simplify future upgrades or troubleshooting.
