I guess that guy has subs.

need to know are they 4 ohm or 8 ohm subs and what the ohm load is on the amp. Im thinking at least a good 2 channel 2 ohm stereo amp.

these subs come in 12w3-d2, d4, and d6 models i believe so that you can use whatever amp you want and nearly any number and get a good end impedance. and as for your other question they are proven subs and are very great performors.

more of a SQ or SPL sub?

if your mono amp puts out 1000 watts RMS, you can power them with it. Just get (4) D2's, wired each sub for series, so they are 4 ohms each. Then Wire 2 of them in series, the other 2 in series. that will give you two 8 ohm loads, then wire those 2 loads in parallel... voila! a 4 ohm load

you can do the same with (4) D4's, but wire the subs for 2 ohms (both voice coils in parallel) and you will have a final load of 2 ohms!

yeah it puts out about 1400rms

AHHHH! Don’t you get it? Do you know anything about ohm loads? Aaaahhhh!

Here it is, your answer and a few others. Where are you getting these subs? I hope you are getting them from an authorized dealer because it sounds like you are trying to build some sort of SPL monster, and will drive them hard. Besides, if you where dealing with a dealer they would be answering all these questions. If you are trying to achieve a SQ setup running your amp at 1ohm is not the way to go. Go to the JL Audio website for more information on ohm loads and nearly any configuration you can imagine.

	4 DVC drivers with Voice Coils in Series / Parallel Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances: Dual-6 Ohm Subwoofers: 3 Ohms Dual-4 Ohm Subwoofers: 2 Ohms Dual-2 Ohm Subwoofers: 1 Ohm

thanks again heavily.......I know that info wasnt directed to me but I also need practice on wiring DVCs. I understand mostly about ohms laws but still have a long way to go with the technical aspect of installations. The website I went to earlier only showed wiring three DVCs in paralell and series. I wasnt sure of the specs Id get for wiring in 4. Thanks again. Big help.
