Please help! Amp and subs parallel setup

Ok I have two RE SE 10" Dual 4ohm 600W RMS subs and a AudioQue 1200D Amplifier to hookup. I've never wired subs before...

Amp power... 510X1 @ 4 ohm, 870X1 @ 2 ohm, 1200X1 @1 ohm

The thing is, I want to connect in them in Parallel (since it's suggested?) but not too sure exactly how. Both subs have 2 neg. (-), and 2 pos. (+) connecters. How would these be connected together exactly and wired to the amp? A diagram would be great if someone has one. Also, can this setup run on a 1ohm load? I believe the amp is 1 ohm stable.

Sorry for the newbie question, but I'm trying to learn this myself and don't want to screw up my equiptment. To expensive to bugger up and I have no one here to help with installation.

Thanks in advance!

Ok the amp is 1 ohm stable thats why it says 1200x1@1ohm
so if your running 2 DVC RE's each voice coil being 4 ohms than its an easy setup.
On your amp there are 2 sets of speaker terminals, they are both the same output there are just 2 of them to make things easier.

The easiest way is to run one set of speaker wire (pos+neg) to each sub, plug that into one of the sets of terminals, then piggy back another set of speaker wire from the pos to the positive and the neg to the neg on each each speaker. You could also run 4 seperate sets of speaker wire one to each terminal on the subs but this creates alot of wire clutter.
1 DVC 4ohm woofer = a 2ohm load
2 DVC 4ohm woofers= a 1ohm load
(per channel)
Remember not to turn it all the way up. A good place to start is to set the gains at half power and slowly work your way up (with the stereo playing) when the sound starts to distort stop and turn the amp back a little bit and your done

So this is what it should look like? ...

note: I'll be using the HU to run the 4 speakers so i guess that frees one set of speaker terminals on the amp, hence why i'd like to use both sets for both subs.

You have the diagram right but the theory wrong.
Remember that the amp is mono meaning 1 channel.
The only reason it has two sets of terminals on it is because the amp companies recognized the fact that alot of people run more than one sub off of mono amps, but hooking 2 sets of speaker wires up to one terminal looks sloppy. So they took the one channel and split it into two (sort of like a Y adapter) so that wiring more than one sub does not create a wire mess.
So in short what looks like 2 sets of speaker terminals on the amp should really ony be viewed as one, the rest is just cosmetics.
Besides you would want to run the HP filter to the fronts and the LP filter to the subs.

In any case the diagram you posted is exactly how you should wire it to achieve a 1 ohm load.
Let us know how it turns out and if you hit any road blocks just ask.

BTW- You should be using at least 4 guage power and ground wire and make sure the ground wire is no bigger than 2-3 feet MAX, (the shorter the better)

Thanks very much for your info. I feel a little safer now haha. Again, thanks Spun.

I have 4 ga. wire for the power and 16 ga. remote wire already wired on the left side of vehicle. Two RCA cables installed on the right side of the car. I have a 150 amp fuse (contacted AQ for fuse recommendation) with holder on order. Also picked up a 2ft 4ga. ground wire for the amp. Getting there! I'll definately let you guys know how it turns out and how much mud I shake off the car :P

Oh and a little off topic... 1200x1@1ohm means that running this setup at 1ohm mono will let me run the two subs at 600w max each?

Yes that right but I wouldn't run your amp at full tilt.
Niether tha amp nor the subs would last very long .
Think of it like running your car with the RPM's at redline everywhere you go, won't take long to blow the motor that way.
I would start at 50% for the first week or two just to break the amp and subs in a bit then slowly each day raise it up little by little untill your comfortable with the sound, distortion and clipping are not your friends, if either of this happens turn it back down a bit.
IMO, myself, I don't like to go much over 75-80% on an amp, amps may be stable at 1ohm but its a fine line when your pushing that kind of power, its like anything else in this world if you don't show it any respect it aint going to work for you.

Question-Did you get the RE's in that shop out in Langley, or did you order them online?

Skip that just read your PM, Good Luck post some pics when your done.

More good advice taken in. thx once again. I purchased the subs via ebay. Price was decent.. (i think), even considering the exchange rate and $75 import fee! *ouch*. I didn't realize there was a shop in langley. What is the price of them there?

IDK the prices of hand but they were pretty cheap, RE/US amps combo's is what they were advertising but I saw it on Craiglist and it seemed a bit sketchy thats why I asked
