What's the ohm rating of the speakers?
Are they single or dual voice coil subs?
How are you running the 2 channel amp? Bridged?
What is the power rating of the amp at 2ohms? 4ohms?
You are correct in that the subs will each get less power when all three are connected because they are sharing the power divided by 3 instead of two or just one. And, just a heads up- be careful not to wire the subs into too low of a load (ie 1ohm or 2ohm) if the amp can't handle those kind of impedances. Most amps in bridged mode are only stable to 4ohm; however, some are stable at lower.
Just my opinion, mixing brands of subs is not usually done because it can sound like poo poo. I might be tempted to run one brand or the other.
