You've Never Heard This from a Factory Stereo
AudioControl makes adding equalization and power to a factory sound system as simple as clip-and-splice!  Splicing RCA connectors onto factory speaker wire enables you to put the signal directly into a DQT (or any other AudioControl product), giving you control over the sound and high quality pre-amp signals, to boot!

Brilliant Sound without Touching the Dashboard
Splicing RCA ends onto factory speaker leads converts a standard OEM radio into a completely customizable sound system, complete with equalization and crossovers for all 6 (up to 8) channels! Mount a DDC in the cockpit, and total control is at the tip of your fingers.
