Factory system holding your upgrade back?
The Delta Box 2.1 & 6.2 make it easier to integrate aftermarket audio while keeping the original head unit in place.
Taking the amplified signal from the factory system and converting it into a clean preamp-level output, they give you the signal you need for adding amplifiers, processors and subwoofers.
With Bass Restoration, up to 40V input, selectable load settings and multiple turn-on options, they’re built to tackle even tricky OEM systems.
