How many Ohm's do I need my mono amp to deliver at for 2 2-Ohm subs?

[ckunke002 10+ year member]

I'm buying two subs that are 500 watts RMS single coil and 2 Ohm's. I want to buy 1 amp is roughly 700-1000 watts to power them both. My question is how will I need to wire these 2 subs together with the amp and what impedance should I be looking for in amps? Since I will have 2 2-Ohm subs, do I need 1000 watts @ 4 ohm's coming from the amp, or just 1000 watts @ 2 ohm's?

Also, what are my different options for wiring this up?

Thanks!

You will need either 1000 @ 4 ohm or 1 ohm. The 1000 at 1 ohm will be cheaper and easier to find.

This. Check out rockford fosgates wiring wizard for wiring options.

Why is it only 4 or 1 ohm's and not 2? And how do I figure out how to wire it all once I have the amp? Also what company makes good 1 ohm amps?

2-2=1

2+2=4

2-2=12+2=4

2-2 actually equals 0, strange as it is. Even if it did equal 1 it still wouldn't quite answer my question. LOL //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Im thinking svc 4ohm, svc2ohm are not that popular.2- SVC4ohms will get you to the 2ohms you want:thumbupw:

The model I want to buy they actually make in 2 and 4 ohm's. I can get whichever is more practical, there's only like a 10 dollar difference. Just in case it matters, they are the 12 inch JL Audio W3's. They come in 2 and 4 ohm's and are supposed to be 500 RMS.

I was actually just thinking about the possibility of getting 2 of the 4-ohm version then hooking those up to a 2-ohm 1000 watt Rockford mono amp. Does that sound good?

IMO opinion JL and Fosgate are both over priced equipment that I won't any longer use since there is so much more out there

Would you mind just listing a couple amp brands and sub brands that you think are a better choice? You probably know a ton more than I do so maybe I shouldn't get this setup lol

Sundown, DC, ascendant audio, SSA dcons or icons, just to list a few for you.

2/2 = 1

2x2 = 4

you multiply/divide ohm loads not add/subtract.
