Got the subs re wired and strapped to the 3500's. Strapped at 1 ohm, so both amps see .5 ohm. Voltage drops a lot. Low 12's, so I'll have to be careful with it. But it is quite a bit louder than my 18! Sealed up it's only .3db's louder, but that's at 9hz lower. Moves a LOT more air and sounds wayyyy louder. With drivers window down it hit a 152! Next upgrade will be something to get voltage to stay higher.
