what the f**k?

It's all about wiring. The model number is Hfi12D4. You can wire to .5 (around 1ohm after impedance rise), or 2ohm (2.5-3ohm after rise).SVCs willgive you 1ohm (1.5-2 after rise)

 
why the single coil? arent the dual coil double the power? correct me if i'm wrong but thats what someone told me on a different forum. he said if its 500rms dual coil then its 2000watts
Number of coils has nothing to do with power handling capability.

 
how would i wire those to a 1ohm load?
This http://www.rockfordfosgate.com/rftech/woofer_wizard.asp will show you.

Seriously, pay attention and maybe you will start to get it. 4 d4 subs can only got to .5 or 2 ohm. I wouldn't recommend going .5 ohm on that amp though. Single 4 can go to 4 ohm or 1 ohm (you want 1 ohm)

 
I think you should take your car to Best Buy, for them to install it, nub. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

everyone acts like they own this forum hah.

but nah i didn't see a 1ohm load for a 2-channel amp and 4 SVC subs..... if you know where it is wanna send that link over this way please?
wtf are you talking about, that amp is a mono amp. Go to bestbuy as suggested above, I don't want you blowing up your alternator/battery
