i have been using this amp for over a year nowpros line in option so you wont need a high line to rca converter if oem deck doesnt have rca output brilliant distortion free output with 2 channels on pioneer components and other 2 on focal coaxials i have also connected 2 channels in bridge mode to the jbl bass tube to chek the output it worked to my satisfaction with about 80 gain enabled in lpf mode however the bass tube needs more power if one is looking for extreme soun
