I've been working out the bugs out of my current setup, which I like. I'm running 2 mm840's off the pa 5000.5. Now the reason I'm not running larger, is the subs hide under my rear seat. I have the option of adding another 10" in my center console with a stealthbox. The box comes with a JL 10W3v3, would there be any real issues with running a setup like this with a 2nd amp? If I could get the box empty I would probably put a mm1040 in it.
