with a dual 4 ohm sub, you can wire it to 2 ohms or 8 ohms. 8ohms and you wont get much power, 2 and your amp will most likely shut off and go into protect.

so really, your only option is to do what mikegett said, and just run one voice coil to one channel of the amp, one voice coil to the other side, but like he said, thats only 90x2 for each sub...not a whole lot, but i think you should be able to push them if the amp has bass boost, if not maybe your deck has a "loudness" or somthing to that effect, because you'll want a little extra punch.

since you'd basically be running them in stereo, make sure the amp is set to mono, if it doesn't have that option, only run 1 signal wire into the amp and split it (you have a red and white, split the white and run both "whites" to one amp, both reds to the other) that way your voice coils wont be trying to do different things at the same time.


you could grab a multimeter and ohm out the voice coil just to make sure its 4 ohm nominal, if your lucky its actually a 2ohm sub. because right now you'll get just as much power running 1 amp as you will with 2.
