Authorized dealer

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".

OVERDRIVE PLUS - 2 Channel Line Driver

High performance car audio amplifiers love lots of signal voltage. This allows them to deliver optimum sound quality and maximum bass response. Unfortunately, many of today's after market source units don't output the optimum voltage levels these amplifier need. The AudioControl OVERDRIVE PLUS pre-amp line driver increases the line level signals from aftermarket source units up to 13 volts max (9.5 RMS) and delivers them downstream to the amplifiers inputs. The results are increased dynamic range, maximum signal-to-noise levels, and tremendous bass response. Autosound enthusiasts will enjoy dramatically improved sound quality of their after market audio system.

The OVERDRIVE PLUS features an optional dash control input which facilitates remote control of pre-amp signal levels. This makes the OVERDRIVE PLUS ideal an a controller for overall system master volume or subwoofer levels.

Key Features:

High-Voltage Line Driver:

The OVERDRIVE PLUS is a line driver that takes the input voltage of a high performance source unit and increases it (up to 13 volts peak). It then delivers this punched up signal to the amplifier for more lifelike sound with less noise, less distortion and more dynamic range. In short: it makes music played on your system sound more like live music. This means the OVERDRIVE PLUS can dramatically increase the pre-amp signal level from your source unit and deliver it downstream to the amplifiers. Higher signal voltage means maximum output, sonic clarity, and the ability to drive multiple amplifiers!

Low Noise / High Current Output Circuitry:

Driving long lengths of cable can present a nasty capacitive load to the source that has to drive them. The OVERDRIVE PLUS' low-impedance, high-current output circuitry can easily handle long cable runs without their associated problems.

Output Voltage Indicators:

Setting voltage levels for best signal-to-noise performance can be a real pain - especially when you have to get out the old digital voltmeter and find a way to make those probes stay put while you try to read the dancing LCD display. With the OVERDRIVE PLUS' voltage indicator LEDs, we remove some of the pain. The first LED indicates that you are in the OVERDRIVE PLUS' comfortable working range. The second LED lets you know you are over 8 Volts and better make sure your amp can take that much input

Easy Interface with Any Aftermarket Installed Systems:

The OVERDRIVE PLUS lets you easily integrate with any aftermarket amplifiers to factory installed source units via a built-in 4-channel RCA Low Level input adapter. Different than most RCA low level adapters, there is no loss in fidelity when using AudioControl's design

Thicker bass and more distinct

Awesome product for sure!!!!
It gives you louder but very clear and distinct thick bass. I would recommend this product to anyone who is trying to build there dream system. The only grip I have with this product is the loose connection when connecting ground,power,and remote wire. Would have been nice if it came pre installed similar to the Clarion 755 eq connections,but Overall the best purchase I made for my system. It was that missing piece that pushed my system over the top. Thanks Audio Control
