AudioControl brings you our most advanced line of LOCs yet. OEM integration has never been easier with the host of intelligent built-in features like LMC™ (Load Matching Circuit), allowing even the most finicky factory sound systems to no longer be an obstacle to great sound. Installer-friendly trigger modes offer flexibility and an expedited installation time since the units can be turned on via GTO™ Signal Sense (DC offset), audio signal sensing, or standard remote 12 volt input. All PRO series products feature AudioContol’s patented AccuBASS® for restoring low frequency output diminished by factory processing, and an ACR-1 level control is included to dial in the perfect level for your subwoofer right from the comfort of the driver’s seat. The Pro series ensures that you will start with the clean, powerful signal you need to take your system from sounding good to sounding great
