Three 10" DVC 2 ohm subs, right? Add up the continuous power handling of 400 watts each...equals 1200 watts. You could use an amp that outputs 1500 watts at a 1 ohm load, but it all depends on the enclosure. Is it big or small or sealed or vented, or what? You're most likely using sealed for those, am I correct? If the enclosure is built to the recommended specs then any output at 1 ohm from 1000 to 1500 watts would be fine. You could even go less, but when you are using three subs I doubt that less is what you want, especially with such a low impedance load on the amplifier (which is not the cleanest power you can get). Strange sig line, my friend. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

thanx for the reply. three 10" dvc(4ohms+4ohms). the enclosure is a subzero mfg triple 10" sealed box, each sub is sealed from the others so i would say its a small box in that aspect. as for the load, if you suggest running a higher load, i can wire the dvc's in series and then parallel the three subs to the amp for a 2.6ohm load. thanx again.
ps...also looking for an h.o. alternator. burned two alts already.

Wire the subs in series / parallel to yield a 2.67 ohm load. How on earth you are magically getting 1.3 ohm with 3 drivers I have no idea. Remember that all drivers must be wired in the same fashion or one driver will receive more power than the other. Find yourself a class D mono amp that is designed and engineered to operate at either 1 ohm or 2 ohm. I would try and find a older Rockford BD1000 series amp for this application as most of them put out more than 1100w rms into 2 ohms. It would be a good match. After that you will need a monster 1 ohm amp and pay close attention to the 2 ohm power ratings on it. The Concept CD2410 might be good in this application. Wiring Option #1

thanx for the input. anyone have any other amp suggestions? i am currently running crossfires and am happy with their performance thus far, thinking of upgrading to the vr2000d. all suggestions welcome.

Nothing wrong with the Crotchfire amps, nothing at all. I like those big nasty beasts...
