Wiring help

I bought a subwoofer(500w) that has two 2 ohm voice coils, I wired them in series, making it run at 4 ohms, but I need it to run at 2 ohms because thats where my amp puts out its most power(600w)
can I plug each coil directly into each sub output on the amp?
the amp im using is a jbl gtr-601


If possible id rather not have to return it and swap it, but if I have to I can

This would result to have a 1 ohm load, that is very difficult for any Amp. That said so is 2 ohm.
Is this for a DIY project?
If so you will be getting better answers, to repost in here;

It's a car amp. (Class D.) Possible to use it in home, but unlikely.

Connecting two 2 ohm loads to it is not recommended. They are paralleled, giving (as you posted) 1 ohm.

I am going to assume he is installing this in a car.
But the answer is still "No it can't be done" because the amp is a mono amp and what appears to be 2 outputs is only actually one.

As you know, the amp will run at 4 ohms or 2 ohms. If you want to operate both VCs for 600 watts, you’re going to need a second amplifier.

And if you want to run at 2 ohms, you will need to buy a second driver.

How do you figure that, since the driver has two 2-ohm voice coils? I’m not up on the latest car audio stuff, so I might be missing something.
