Which is better 2 ohm or 4 ohm subs

Im thinking about gettin a Kicker S12L5 and wanted to know which one is better the 2 ohm or the 4 ohm, or does it really matter. Im kinda new at all this stuff, and was just wonderin.

there is no better, You just have to base it off the amp you are going to be using

Jack...Haibane is correct. The reason the subs are available in different impedances is for different configurations. Lets say you have an amp that will do 1 ohm mono and you want to use 1 sub. Then a dual 2 ohm voice coil sub is what you want. If you want to use two subs then you will need 2 dual 4 ohm voice coil subs or 2 single 2 ohm voice coil subs. The impedance is so you can match your sub configuration with your amplifiers for the best possible results.

Thanks a lot, I have an old piece of crap amp my dad had when he was my age, I dont really want to use it but I will if I have to. What are some good amps that yall would recomend for a kicker sub? Keep in mind Im on a VERY tight budget, lie $100-$150 max.

i'll sell u my Kenwood amp for $90 i used it to power to 2 S12L5's u can bridge it at 4 ohms or have 2 channels at 2 ohms
