Today’s cars are all wired up into themselves. So much so that you can’t upgrade the head unit because it can open your garage door and shut off your home alarm. So what do you do? Get hooked up with “BLUELINE” an OEM line/drive converters that can take 12 separate OEM channel speaker inputs. BLUELINE uses an auto music sensing turn on with 12V out. The systems can auto sum 2 separate 6 channel network groups for full control of F/R channels! With Blueline you get the added OEM feature of auto on/off “Wireless Streaming” of a phone or portable audio device via Bluetooth! A built in audio decoder and D/A convertors sample the streaming audio @ 44.1 KHz. Adjustable outputs levels (>4.8V RMS and an S/N Ratio >105dB) let the installer fine tune any OEM source/ unit into a Massive Audio Power House without losing your head!!
