i have had the same set up for 4 years and everything still works and sounds like new
only problem ive had is the bass knob thingy
couple questions
how do you know if the HU has sub control?
my box is big and open and 1' thick mdf so what does it matter if one sub is out and the other is in?

Technically speaking, the kick of bass is determined by your mid speaker and how well it matches up with the sub. That means install and tuning are paramount! You can EQ your tweeter and change the sound of "bass"

Go to an audio competition and listen to different setups. Notice their mid configuration in comparison to subs.
