I PHUCKED up dearly, can someone help me? simple ohm problem.

[eb2phkingood 10+ year member]

I had this sub sitting in a closet forever:

Rockford Fosgate P212D4 - Sonic Electronix

and then i bought this amp off craigslist for a STEAL of 20$:

http://www.cadencestore.com/ProductCart/pc/viewPrd.asp?idcategory=100&idproduct=260

as you can clearly see though, the sub is dual 4 ohm, and the amp is not made for that. What is the best way to wire this for the time being until i get a proper subwoofer to match this amp? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

run it at 2ohm

1) how would that be wired??

2) is that safe for the sub and amp?

thanks

**ya, its safe...y wouldnt it be??...the amp is 2ohm stable and that sub is actually really good low end equipment...i had 2 12s on 800w and it banged pretty good

the amp is 2 ohm stable in stereo. DO NOT HOOK A 2 OHM LOAD UP BRIDGED!!

wire it 8 ohm series and bridge that , it will see 200 rms that way.

Sell it and get better stuff

this is the amp you recommended i buy for the cheap *** project i told you about off ebay. and the sub was the one i told you that was dual 2 but turns out i F'd up and its dual 4 //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif((( good thing its for a high school project for my brother and not a car lol

Coil 1 positive to positive bridged terminal on amp

coil 1 negative to coil 2 positive

coil 2 negative to negative bridged terminal on amp.

=8 ohm load bridged

 

[stangman67 10+ year member]

I do remember but now you screwed it up, so sell both and go a different route, there isn't much you can do except run it off a single channel

coil 2 negative to negative bridged terminal on amp.

No reason to do that. Just run it 2 ohm stereo

 

[stangman67 10+ year member]

You could also run a coil off each channel I guess

why?? he can get more bridged at 8 ohms then he can off a single channel. OP , read my sig , it applies to this guy. LOL

so the 8ohm load he is talking about above is only a single channel?

i've had better luck in mono in this situation. say he has a track that basses hard on the left channel , it will only push one coil and that can be nasty especially if its a note thats in phase on one channel and outta phase on the other. it will literally pull the 2 coils in different directions. which will lead to woofer failure. mono will be safer.
