It wasn’t long ago that I found myself in a familiar predicament, staring at my car’s factory stereo system with a sense of inadequacy. I longed for that deep, resonant bass and crisp, clear audio that aftermarket setups promise, but the thought of tearing out my perfectly functional head unit was daunting. This challenge of integrating a powerful amplifier and subwoofer into a stock system without sacrificing factory features was a common hurdle for many, and it desperately needed a straightforward solution. Without one, I knew I’d be stuck with flat, uninspiring sound, missing out on the full richness of my music.
For anyone looking to significantly improve their car audio without replacing the entire head unit, a line output converter (LOC) is often the unsung hero. These devices are designed to bridge the gap between your car’s existing speaker outputs and the low-level RCA inputs required by most aftermarket amplifiers. They solve the fundamental problem of converting a high-level speaker signal into a clean, low-level signal that an amplifier can properly utilize, allowing you to add subwoofers or upgrade your full-range speakers with more powerful amplification.
The ideal customer for a line output converter is someone who is content with their factory head unit’s features – navigation, steering wheel controls, aesthetic integration – but yearns for better sound quality or the addition of a subwoofer. It’s for the DIY enthusiast who wants a cost-effective upgrade without diving into complex wiring or risking damage to the car’s interior. Conversely, if you’re planning a complete overhaul of your car’s sound system, including a new head unit, then an LOC might be an unnecessary step, as most aftermarket head units come with built-in RCA outputs. In such cases, investing directly in a quality amplifier and speakers would be more suitable.
Before purchasing any amplifier add on module, you should consider several factors: the power handling capabilities (how many watts per channel it can accept), the number of channels you need (2-channel for a subwoofer or 4-channel for full-range amplification), whether it includes a remote turn-on feature, and the presence of any level adjustments. Sound quality is paramount, so looking for a converter that minimizes signal degradation and noise is crucial. Compatibility with your specific car stereo and the amplifier you plan to use is also a non-negotiable step.

Unpacking the Capabilities: Features and Advantages
Having spent a considerable amount of time with the Scosche LOC2SL, I can confidently delve into its features and the real-world benefits they provide. This little black box has been a game-changer for my car audio, allowing me to finally achieve the sound I’ve always wanted without a major overhaul.
One of the standout features of the Scosche LOC2SL Line Output Converter is its ability to convert high-power car stereo speaker outputs to RCA cable outputs. This is fundamental. Most factory car stereos, and even some aftermarket ones, only provide high-level speaker wire outputs. To connect an aftermarket amplifier, which typically uses low-level RCA inputs, you need a bridge. The LOC2SL effectively acts as this bridge, taking the raw, amplified signal from your car’s speaker wires and converting it into a clean, low-level signal that your new amplifier can understand. This means you don’t have to splice into sensitive, low-voltage preamp circuits or worry about signal degradation often associated with lesser quality converters. The benefit here is immense: you can retain your stock head unit, along with all its integrated features like Bluetooth, navigation, and steering wheel controls, while still getting the full benefit of a powerful external amplifier for your speakers or subwoofer. For me, this meant no loss of factory aesthetics or functionality, which was a huge selling point.
Another incredibly useful feature is the signal sensing remote turn-on output. Historically, adding an aftermarket amplifier to a factory stereo meant finding a 12V switched power source to trigger the amplifier’s remote turn-on. This often involved tapping into obscure wiring, checking fuse boxes, or even running a dedicated wire from the ignition. The Scosche LOC2SL simplifies this dramatically. It senses when an audio signal is present from your car stereo and automatically sends a 12V signal to your amplifier, turning it on. When the audio signal stops, the amplifier turns off. This completely eliminates the need to hunt for a separate remote wire, making installation significantly easier and cleaner. For anyone who has ever wrestled with car wiring, this feature alone is worth its weight in gold, streamlining the process and reducing potential complications. It ensures your amplifier powers on only when needed, saving battery life and preventing unwanted noise.
The inclusion of a mountable remote control knob for adjusting subwoofer levels from the dash is a testament to the thoughtful design of this amplifier add on module. After installing an amplifier and subwoofer, you often find yourself wanting to fine-tune the bass response based on the music genre, passenger preferences, or even road noise. Without a dedicated control, this usually means pulling over, opening the trunk, and fumbling with gain controls on the amplifier itself. The remote knob provided with the Scosche LOC2SL allows for on-the-fly adjustments, giving you immediate control over your subwoofer’s output. You can easily mount this discreet knob in an accessible location on your dashboard, providing unparalleled convenience. This functionality truly enhances the listening experience, allowing for dynamic adjustments to suit any audio preference without distraction or inconvenience. I found myself using it constantly, dialing in the perfect amount of bass for every song.
Furthermore, the LOC2SL boasts independent left or right channel level adjustments. This feature is crucial for achieving balanced audio. Different car stereos or even different speaker channels within the same stereo can sometimes output signals at varying levels. Being able to independently adjust the output gain for the left and right channels on the LOC itself ensures that your amplifier receives a perfectly balanced signal. This prevents one side of your audio stage from sounding louder or weaker than the other, contributing to a more accurate and enjoyable sound reproduction. When setting up my system, I appreciated the ability to fine-tune these levels to ensure a cohesive soundstage, especially since I discovered that my factory head unit had different output levels for my front and rear channels, as some user reviews pointed out. Connecting the LOC to the optimal channel, whether front or rear, made a world of difference in sound quality.
The Scosche LOC2SL Line Output Converter is designed to work with high power car stereos, up to 80 watts per channel. This specification is important because some factory stereos can put out a fair amount of power. A line output converter needs to be able to handle this input without clipping or distorting the signal, which would lead to poor sound quality. The LOC2SL’s robust design ensures that it can accept these higher-level signals and cleanly convert them, providing a clear and strong low-level signal to your aftermarket amplifier. This capability directly translates to a cleaner audio signal being passed to your amplifier, which in turn leads to a more powerful and distortion-free output to your speakers or subwoofer. It ensures that the integrity of the sound is maintained even when dealing with more powerful factory systems.
Finally, the overall ease of installation of the Scosche LOC2SL cannot be overstated. With clear wiring diagrams and a straightforward design, it’s manageable for anyone with basic car audio knowledge. You essentially splice into your speaker wires (often behind the head unit or at the factory amplifier location), connect the RCA cables to your amplifier, and wire up the power, ground, and remote turn-on (which is made easy by the signal sensing feature). The compact size of the unit (Item dimensions 5.4 x 16.8 x 33.7 Centimetres, though the unit itself is much smaller than the package) allows it to be tucked away discreetly, maintaining a clean installation. This simplicity saves time, reduces frustration, and makes a significant car audio upgrade accessible to a much broader audience, including those who might be hesitant to tackle complex installations. While simple, it’s always worth double-checking your wiring, and sometimes minor adjustments (like selecting the correct factory channel) can make a huge difference, as per other users’ experiences.
