Here at Sound Depot and Performance, we are constantly searching for the best solutions to meet our clients’ needs. Until now, adding on to select 2007-2017 Chrysler, Dodge, Jeep, Ram and Ford factory head units has presented a challenge. With the release of the PAC AP4-CH21, AP4-CH41 and AP4-FD21 interfaces, we can now provide great solutions for these vehicles.
Data-bus Control
Starting in 2007, the factory head units in many of these vehicles began to use data-bus controlled audio systems, where the volume knob no longer controlled the signal level going to the amplifier, but instead, controlled the amplifier volume directly. This created problems in trying to upgrade the factory system because the signal coming out of the head unit was constant and not controlled by the volume knob at all. The only solution was to go after the amp and use complex summing devices to put the signal back together. That is not only time-consuming, but adds one more layer of distortion from the factory amp.
The First Interface Before The Amp
The PAC interfaces are the first adapters that allow you to get a clean signal from the factory amp and tie it into the data-bus control for volume. It allows you to build a great system off the factory head unit – with less time and better sound. You can use the unit to adjust the volume, balance and fade, as well as bass, mids and high frequencies to fine-tune your sound. This unit gives you a true flat signal that is ready for any level of system that you want to build. With its 5 volt pre-outs for front, rear and sub, you are ready for that system upgrade. There is even a separate bass knob to really fine-tune that element!
