Posted January 31, 201312 yr Planning a build in a 2012 hyundai sonata with the infinity premium system while retaining the stock unit Here's what we have so farHybrid audio clarusjl hd 600/4 + 750/12 jbl gto 12's(IB)No processing as of yet since the head unit schematic is very tricky. Now, from the information I've gatheredThe stock head unit has a digital out(spdif) that goes to the factory amp. Usually, you'd go straight from head unit to processor, but, if you bypass the factory jbl amp, you lose bluetooth, xm, & am/fm radio. I'm about 90% sure the speakers crossed inside the amp, so I'm lost on what to do here. Tapping after the amp seems like the only option, but I can't seem to find out if the signal is full range or not. What can I do? Do I just install a processor and hope for the best?Here's the schematic
