Understanding Ohms (audio)

[Jrew]

i was looking at pairing a clarion pxw1251/52 sub with a clarion dpx1800 amp. However, the 1251 is a dual 2ohm where as the 1252 is a dual 4 ohm. I want to pair it with the amp only if I can run it at 2 ohms but i didn't know if the amp could handle that. here are the links for both:

Maybe I am incorrect however. Don't you wire the dual coil sub in series so that it equals 4 ohms? or can you wire it so that it is just 2? im slightly confused on that matter. Thanks for the info so far!!

You want a 2ohm load in order for that amp to make 800w. In order to do that you need a dual 4ohm voice coil sub wired in parallel. If you wire it in series, the amp would see 8ohms(4ohm+4ohm). If you went with a dual 2ohm voice coil, and wire it in series the amp would see a 4ohm load giving your sub 450w. If you went with the 2ohm and wired it in parallel the amp would see a 1ohm load and probably fry itself. So yes, you can wire it in series so it would see a 4ohm load but only if you use a 2ohm dvc sub. Get the 4ohm sub and wire it in parallel and get ready to jam! I'm running an Alpine Type R 10 4ohm dvc wired parallel with an Alpine mono amp and it's more bass then I could ever need! I chose Alpine for the sound quality.

Crutchfield has a pretty good def here

Go to www.Caraudio.com to the forum section and post their, they are very helpful. Youll get imput real fast.

Why are you going with clarion? Is it cause the subs seems massive? You do know that those subs are 500watts rms right.

Heres how it goes if your only buying one subwoofer, and assuming you buy a monoblock amplifier.

dual 2 ohms voice coil subwoofer= 1 ohm stable amplifier. wired in parallel



dual 4 ohms voice coil subwoofer= 2 ohm stable amplifier. Wired in parallel
