You can't

2 dual 2 ohm subs can only be wired to 2 ohms or .5 ohms, neither of which can be run safely with your amp. You could run each sub to it's own channel @ 4 ohms, but then you would be getting hardly any power out of an amp that is overrated anyway. Just wait man and don't try it, it's not worth torching your subs.

we sell these amps at the shop i work at.. and im quite confident u can try running it at 2 ohm bridged.. im confident it will work.. u know just odnt get carried away and give it time to cool down once in a while and be carefull with the gain.. it will work.. :-)

we sell power acoustic amps at the shop i work at.. and they are only stable 2 ohm stereo.. and 4 ohm bridged.. however if you carefull with it you can run it 2 ohm bridged and it will work fine.. just be carefull with your gain and watch the heat..

yes you just take the positives and negatices form both woofers.. alright ad you twist teh positives together.. and on the amp there will be a thing that says bridged.. and it will have a line drawn to one positive on the amp and one negative.. you simply use those two for both your woofers..

the thing i dont get is that there should be a pos and a neg for each sub right?? well then if i wire it to a 2 ohm like this:
http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?subs =2&impedance=DVC2x2

then there is only 1 pos and 1 neg for both subs. thats where i get confused. for a 2 channel amp there is only 1 pos a neg when there should be 2 of each. do you know what i am trying to say??? i know its confusing.

a + and - = 1 voice coil

if your sub is DUAL voice coil it will have = + and -, and + and -

i dought you want to run your amp at .5 ohms, makes it work too hard. if you have 2 dual 2 ohm subs, you can only wire to a 2 ohm load (because thats the best you will find on an amp) use www.the2volt.com

where the speaker wires from the subs GO INTO the amp, thats where there is only going to be a + and -, (when you have it hooked mono) or if you do a speaker per channel (so for a two channel amp) you would get the diagram that you need, and do that for each sub, and just hook it to one + and - on the amp. i hope that didnt sound too confusing. :-(

lets start from the beginning. you have 2 dual 2 ohm subs correct, and what amp are you wanting to run?

its not gonna power the fi q's very well, BUT since the power ratings are:

# 440 watts x 2 RMS @ 2 Ohms
# 880W x 1 RMS Bridged Mono @ 4 Ohms
# 370 watts x 2 RMS @ 4 ohm

i would wire each sub to its own channel @ 4 ohms. so, wire like this, onto each amps channel:

Upload

so basically wire each sub exactly as its shown in the picture, and then connect the + and - wires comin out of one sub to ONE amp channel, and then the othr subs the same thing, but to the 2ND amp channel :-)

if you wire each sub to 4 ohm and run it stereo it wont put out any power.. just wire each one to 4 ohm and bridge it at 2 ohm.. that will work fine..
