    THUNDER Road

    The Road Thunder RT500D car audio amplifier is a masterpiece of power, efficiency, and sound quality packaged in a form that is easily mounted and displayed or hidden anywhere in your vehicle. The RT500D includes a ton of technology that has been perfected over 25 years industry experience in manufacturing unbeatable car audio amplifiers. It can output up to 500-watts RMS power into a 2Ω impedance load making it perfect for driving dual 12" subwoofers.

    Patented Class D

    The RT500D uses a patented circuit, Adapative Class D, that reduces interference caused by rogue frequencies generated by the internal MOSFETs during use. This ensures that your bass notes are clear and defined, delivering the bone rattling bass you want from your subwoofers without any unwanted noise. Additionally, this circuit effectively manages heat build up in the amplifier and dissipates it across the heat sink ensuring long play times with no interruptions. The circuit board is dual layer with twice as many copper traces as competitive amplifiers ensuring reliability.

    System Engaged

    Connecting the RT500D to a factory system is very easy using its integrated Smart Engage technology. This technology allows you to tap directly into your vehicle's factory speakers to get signal to the amplifier as well as to turn it on. This means you dont even need to take the radio out of the dashboard in order get everything working using the included low to high level adapter cables.

    The RT500D includes a wired external bass control allowing you to control the bass level from the driver's seat.
