Do you have those amps and subs hooked to the factory head unit? Via a high level output from the original sub box or some of the other speakers? How does it sound?

Yes, it is all running from the factory head unit. I have the rear channels hooked to a Line Output Converter and then the RCAs go to the amps. This is the non-amplified head unit.

It sounds great, the wattage is a little more than the subs are rated so I have to keep the gains low. All in all I am very happy with how it turned out.
