Did you check to see if both coils are functioning properly? You may have previously burned up one of the coils on the subwoofer with less excursion.. Make sure one coil isent fried. you can do this buy just hooking the coils up one at a time and seeing if the subwoofer will play, or just measure the resistance with a ohm meter, they should read around 4 ohms for each seperate coil.

If the subwoofers sound different with it wired the way you have it now than it was not wired in parallel from the beginning. Doesn't matter if you run two sets of wires to the amp or one...there is no difference if it is a 1 ohm load.   Besides the lower resistance with two sets of wire. But that is negligible.Custom Enclosure Design

Your meter measures the DC resistance of the voice coils. Impedance is an AC measurement. 1.8 does seem more like a reading of 3 4ohm coils (1.66). You may have an open voice coil on the passenger speaker.

will check all 4 coils and get back with you. Could this just be the enclosure sinc if i move the driverside sub to the passenger side spot it will do the same thing. And my amp sound better when I wired them that way I set the gain to 30volts. with a 50 hz 0 db sine wave. It seems to hit alot harder at 45 volts but I was told from local shop that 30 volts is 900 watts and that is just about right for my subs. I have no bass boost on or bass eq all is at 0. sound clear just not as loud as I think it should be. Maybe im just trying to compar this system to my 2005 chevy caviler that i had with a rockford fosgate p3 dual 2 ohm wired at 1 ohm with a kenwood excelon 811d at 1 ohm. that rattted everything within 10 feet of the car.
