He doesn't necessarily need a new subwoofer. Its the amp that is the problem.
John_Taylor is right. He needs to find out at what resistance that amp puts out 700W.
If its 700W at 4 ohms, he's hurting the sub. If its 700W at 2 ohms, then he'll be putting 350W at 4 ohms. Which would be ideal. Give us the model number of the new 700W monoblock amp, and we'll let you know whether or not this new amp will work.
Disregard the fact that it states that the Dual amp is capable of producing 600W. If it could, there would be a line somewhere that read: 600W x 1 @ 1,2 or 4 ohm.
The most power you can squeeze from this amp is 300W. 150W for your subwoofer, by bridging the rear channels at 4 ohms. And 75 whats for each front channel, but you'd have to use 2 ohm speakers for your fronts. For a total of 300W. Since this setup is in your room, you could wire a pair of speakers in parallel for each front channel. So you'd have a pair on your front left, and a pair on your front right. Two 4ohm speakers wired in parallel will provide a 2 ohm load to that amp channel, which in turn will output 75W. Since you have 2 speakers on the channel, they'll share that 75W and use 37.5W each. And you'd do the same for the other channel.
If you're just taking the subwoofer and using one channel's +/- terminal to power that sub, then you're only putting 50W to it.
You have a camera? Take a picture of that amp, and where you have all the speaker wires connected.
Keep the Dual amp to power your front and rear speakers. Pick up another amp that is rated for 250-350W x 1 @ 4ohm, then you're laughing.
Here's some amps that would work. Depends how much you're willing to spend, or if you can find one used.
Exile Monoblock 1-Channel Car Amplifier (S500.1)
Pioneer 800W Class D Mono Amplifier (GM-D7400M)
Clarion APX1301 420 Watts Mono Amplifier
Sony XM-1S 900W Slim Series Class D Subwoofer Amplifier
