4 ohm? 2 ohm?

I recently got a Bazooka ELA300.1 amp. I was wondering how ohms is calculated. Does it have to do with the speaker or the amp. I havent got any subs yet but according to the specs 2 ohms is better.
4 ohm- 200Wx1
2 ohm- 300Wx1
Thanks in advance

im not 100% sure but for one thing, 2 ohm supposed to make 2X the power of the 4 ohm, lets say,
on a 2 channel amp
150 x 2 @ 4 ohms
300 x 2 @ 2 ohms
600 x 1 @ 4 ohms
on a 4 channel it should be like
50 x 4 @ 4 ohm
100 x 4 @ 2 ohm
Bridged 200 x 2 @ 4 ohm
on a class D it should be
150 x 1 @ 4 ohm
300 x 1 @ 2 ohm
usually people get 2 ohm subs because u can get more power out of it for cheaper, there are also dual voice coils that come in dual 2 ohm dual 4 ohm and 6 and on, when u have dual voice coils the subs are more flexible, and MUCH easier to worth with, all u gotta do is read how to wire subs online somewhere

the ohm or impedance is determined by the speakers

half the impedance does not always mean its going to be double the power. That's usually the case, but not always. Viper: to get the most out of your amp get 2 single 4 ohm subs, one dual 4 ohm sub, or one single 2 ohm sub. Other combinations that would work is quad 2 ohm, dual 1 ohm, two dual 2 ohm subs. Wiring in series will give you the impedance of each coil muliplied by the number of coils, while parallell will give you the impedance of each coil divded by the number of coils.

Thanks for all the help.
