Question about adding another sub to existing system.

[Khammett1962 10+ year member]

I've had an Infinity KAPPAONE 800 Watt amp and a Kappa 120.9w sub in a sealed box to go with it in my Ford Escape and I've had this set up for a few years and have loved it. So much so that I had the same setup in my other vehicle. It sounded great as well. The only problem is that it was lacking in the volume aspect just slightly. I recently got rid of the other car and sold the other amp but still had the other sub so I bought a dual sealed box and thus solved my problem with the very small lack of volume/punch. Now, the question is, seeing as how the subs have the selectable Ohm switch on them, would I be better off with switching both subs to 2 Ohms or 4 Ohms? Currently they are both set to 2 Ohms and it sounds good as it is but I just want to be sure that it's the best way to go since I'm really unsure. Any insight as to my best course of action would be greatly appreciated. Thanks

Setting each sub at 2 ohms is the best way to go. This yeilds a 1 ohm final load on the amplifer.
