Is there just one set of positive and negative terminals? Or are there 2 sets of positive and negative terminals?

oh ok.. theres only one set so its a single...

Ok, so what you need to look for is an amp that provides 400 watts RMS at 4 ohms.

I'd check out kicker, hifonics or MTX if you're looking for an inexpensive, yet good amp.

Are they 2 or 4 ohm speakers? If they are 4 ohm each you need an amp that does 400 rms at 2 ohm.

ok.. im kind of confused now...

at this site it says dual 2 ohm....

so since its 2 ohm do i need 400 watts RMS at 4 ohms like ridr4lif said?

sorry for the noobiness...

Check with RF's website in their archives. I found this really quickly

If these are the subs then it appears they are single voice coil in either 4 or 8ohms, for your sake I hope they are 4.

If the site you posted first is the exact place you bought them then they are single 8ohm because it says it in the description.

The sub(s) you have are 400rms at 8ohm. So you need an amp that does or is close to 400rms at 8ohm.
