12 not thumping why?

The sub is wired like this: there are 4 terminals on the sub. the black terminals are individually wired to one red terminal then they are wired to a box connector then on the outside of the connector to the AMP. Since it is wired this way I would suspect 2 ohms impedance? I dont know about it though as I am just getting into car stereos. The gain is set on the NORMAL setting. There is a min 4v setting then a normal setting and then one more higher. Everything else I have set to just above the MIN settings on the dials.

WHOA WHOA WHOA!  Take the sub out of the box.  Connect both black (-) terminals together, and connect both red(+) terminals together.  Then connect the two reds to the red terminal on your box connector, and the two blacks to the black terminal on your box connector.  This will result in a 2 ohm load to your amplifier and you will be fine.  Hope it helps!

you still haven't answered what impedance the coils are Use this calculator and wire the subs correctly Woofer wiring calculator

it says on the back of the sub 4ohm+4ohm so does that mean it is an 8ohm Sub?here are the pics of the sub when I took it out today.

here is the link to the sub information http://www.crutchfield.com/S-ZPOet0mqPcI/cgi-bin/ProdView.asp?i=500SWR1241

here is how the dials are set on the AMP. Kind of hard to see but that is the best my camera can do.The gain is set to the very MIN now.

How did you set your gain?? What level was the head unit on??? What level was the sub level set at?? Where is your crossover set at?? Check to see if the rcas are loose behind the head unit Those pics are blurry and hurt my eyes lol

Looks like your woofer is wired correctly.  Take a look at the crossover settings.  Set the LP on the amplifier all the way to its max setting, or bypass the crossover on the amp.  Check the subwoofer crossover setting in the head unit and set it to, oh, 80 or 100 Hz.  Then set your amplifier input gain properly.Support the12volt.com

SWR1241D Sub. Tested the connections on the sub C1- 1.1 ohms C2- 3.8 ohms Hooked it back up to the amp. The Amp is working. The Light is on. Turned on the stereo andset up the subwoofer settings on the HU at the connectors on the box I get with no music C3- 11.0 ohms Settings on the Amp Gain- set to min Bass EQ- 0db Lp filter 50Hz HU Settings Sub output- ON Sub output level 0-15 Set to- 10 Turned on the tunes....... Once again with the music low and all the settings set where they are, pretty much nothing coming through. Turned the gain up to Avg, the sub started to come to life. But it sounds like crap. Adjusted the Bass EQ around and Adjusted the LP Filter around. The sub started to make more sub sounds but it sounds like crap. Kind of if you put your lips together and made a fart pipe sound from a dirt bike. I turned the volume up to 25. The system sounded like doodie and the sub stopped working all together. I think this sub is FU@#ed Up.

SWR1241D Sub.

Tested the connections on the sub C1- 1.1 ohms

C2- 3.8 ohms

Am I reading this correctly?

1 coil is 1.1ohm   and the other is 3.8?

Thats not quite right.

yeah something isn't right at all try using only the coil that reads 3.8 ohms
