Sorry mate but that amp is not 1-ohm stable, 2-ohm and 4-ohm only. And since those are dual 4-ohm subs, if you use both subs than the best you can achieve is 4-ohm, which means only 500wrms from the amp.

This is how you have to wire them.

13.8v isn't bad with the car running. If your worried take it to an auto sparky or battery place they can usually do a free test.

Voltage drop is usually associated with a wiring problem, can you take a photo of the spot where the ground cable is bolted to the chassis?
