I need some help wiring my subs to my amp. I have blown two subs alreadly...

I have a 1000 watt 2/1 channel amp and 2 600 watt single coil subs.

Power output from the amp is as follows: 380 watts x 2 at 4ohm, 500 watts x 2 at 2ohm, 1000 watts x 1 at 4ohm.

What's the best way to wire the subs in order to get the most power to the subs without blowing them?

What is the impedance rating of the speakers?

4 ohms each

That's too bad.  The most you can safely get with this combination will be connecting one speaker to each amplifier channel (or using the woofers in series and bridging the amp, which is the same net power.)  You'll operate at the "380 watts X2 @ 4-ohms" rating.  There is no other safe configuration.  And be sure you set you amplifier gain properly.

Actually, he's stretching the truth a little bit. There is one other way to safely wire the subs but it yields the same result. That said though, wire one sub to one channel, the other sub to the other channel and call it a day. Do a search for gains or gain setting and read up on it.

That's what I was thinking. Is it possible to hook up up the subs in a parallel curcuit (at 2 ohms) that includes a 2 ohm resistor to increase the overall impedance to 4 ohms?

This will get you no improvement.  You have the wrong amp for those subs, or the wrong subs for that amp.  The only other safe way to hook up your system is to use only one sub.
