I'm not 100% sure what he meant but from what i understand of the Pac TR-4 it brings the remote wire power in slow not just straight 14v but a gradual build to 14v. The subs are dual 4's reading around 4 ohms at each coil not wired, they are wired down to 1 ohm. The amp is grounded to the extra batteries in the back and the batteries are grounded to the frame and the contact points are bare metal. The head unit I have is Power Acoustik PTID-8920BT
