These could be Rockford Fosgate's or Lightning Audio's, you will need more information before anyone will anwser with advice.

What make and model, how many voice coils and the impedence of the coils

example: Make and Model
(2) Rockford Fosgate Punch Stage 3 P310D4- each has 10" woofer with (2) 4 ohm voice coils

You have some options: THIS MAY BE HARD TO FOLLOW

You can run 1 stereo amp with a 2 ohm load- wire each woofer in parellel for a 2 ohm load, hook both up to each channel, make sure your stereo amp will handle a 2 ohm load.

You can use 2 stereo amps- each amp hooked up to the woofer's 4 ohm coils.

You can use a mono amp by taking 1 speaker's 4 ohm coils, putting them in parellel for a 2 ohm load. Then repeat this for the other speaker. Take both of the 2 ohm loads and put them in series for a 4 ohm load. This would make the mono amp see a 4 ohm load at it's output.

***( OR ) *** Amp will see the same load as above ***

You can use a mono amp by taking each speaker's 4 ohm coils and hooking them up in series for a total of 8 ohms and then taking both 8 ohm loads and put them is parellel for a 4 ohm load.

Some high dollar mono amps are stable to 2 ohms, I think there is even a few that will handle 1 ohm. If you have something like this, you may want input from someone that is using this set-up.
