what config did you have the subs. if the ohm load with the one 12 was less then when you had 2 it will draw more current.

If you're voltage is dropping to 11.2 your charging needs to be upgraded.It's that simple.There's no other reason for your voltage to drop aside from a poor charging system or running super high current demand in a high power setup.

ok here's a better explanation from a post I just made about my bro's situation...

Its a regulated amp

as you guys know we own the phoenix gold xenon 1200.1 it puts out 1200 watts rms at 1,2,3 or 4 ohms anyway..... we had it hooked up in 2 ohms using one terminal on the amp and we had voltage drop to 12.5 to 12.6 volts and hit 138.1 db......then we hooked the sub up to both terminals on the amp at 2 ohms and hit 139.7 db and voltage drop to 11.2 volts.....my questions is why did we hit 1.6 db more when the amp puts out the same power in both wiring arangements ...and why did we get voltage drop like that when the amp puts out the same power either way

we just tested more and burped it at port tune (45 hz) at 45 hz test tone and hit 141.5 db with voltaqe drop to 11.7 volts....this sub seems to LOOOOOOOOVVVE the low end...previously every sub we put in our suv hit best at 55 hz (three different subs)....were gonna mess with the port tune for the ti elite now and see if we can get more spl out of it
