MTX TL-45L (TL-4.5L)

Premium Factory Audio Integration

MTX TL-4.5L provides a definitive solution for bridging modern factory audio systems with high-performance aftermarket amplifiers. Engineered specifically as a 4-channel in, 5-channel out Line Output Converter, this robust unit allows you to dramatically upgrade your vehicle's sound without replacing the original head unit. By seamlessly processing the factory audio signal, it ensures a frictionless audio experience that delivers a strong, crystal-clear preamp output specifically tailored for your new amplifiers, preserving the aesthetic and core functionality of your dashboard.

High-Voltage Signal Handling

Beyond its core conversion capabilities, this premium processor is meticulously built to handle extreme audio demands from advanced factory systems. Designed to accept a wide variety of OEM speaker-level outputs, the TL-4.5L can comfortably process input signals up to an impressive 40 volts or 400 watts. By easily managing high-wattage inputs from both base model and premium factory sound setups, it guarantees a reliable, distortion-free signal delivery to your aftermarket gear, preventing the clipping issues commonly associated with inferior converters.

Intelligent Load Resistance Matching

Modern factory radios often shut down or mute specific channels if they detect that the original speakers have been removed or altered. To counter this, the TL-4.5L features selectable load resistance settings, including 20-ohm, 60-ohm, and 20k-ohm options. By utilizing these intelligent impedance settings, the converter perfectly simulates the electrical load of factory speakers, ensuring that your vehicle's intricate OEM amplifiers and head units continue to operate normally while driving your newly installed aftermarket equipment.

Flexible Turn-On and Control Options

Taking command of your upgraded soundstage is practically effortless thanks to the highly adaptable turn-on and output controls. The TL-4.5L offers multiple remote output and activation modes, including DC offset sensing, audio signal detection, and traditional 12-volt remote turn-on configurations. By providing dedicated gain controls for each channel, visual clip indicators, selectable ground isolation to eliminate noise, and an included remote bass level control, this high-quality converter allows you to confidently fine-tune your entire system for a professional-grade acoustic experience.

Compact and Install-Friendly Design

To accommodate complex vehicle integrations, this high-performance line output converter is built into a highly compact, installation-friendly chassis. Measuring just over five inches in length and roughly an inch thick, the TL-4.5L makes mounting incredibly easy, fitting comfortably under seats, behind factory trim panels, or right next to your new amplifiers. By utilizing this ultra-small footprint, it allows professional installers and DIY enthusiasts to secure maximum system flexibility in modern vehicles where valuable cabin space is heavily restricted.
