You can read more about the new JL Audio processor here , scroll towards the bottom of the post. Sorry, saw this comment after I responded to the other one.
Your subs are rated at watts RMS each. Another problem you may encounter when wiring an amp and sub into a premium factory sound system is the signal level may be too high or too low. The factory system is the beats audio. Installed a sub and amp.
Now that you have your speaker wires figured out, we can move on to the remote turn on lead.
The place where i got the amp installed said that my oem unit cant be amped. I would add one clarification to your speaker polarity testing. The installation is quick and easy and won't require removing your factory head unit. These inputs look like regular speaker wire inputs and they will be labeled "speaker-level inputs" or something very similar.
