I am Beggining to understand the combination of the amp and speaker but i am not sure about the factor that the amount of ohms the speakers and amp need.  could someone [please let me give me some advice on what kind of amplifier i should get to power 2 Kicker 05S12L5-4, 12" dual 4 ohm voice subwoofers with

50-600 watts RMS

and 1200 watts peak power handling

there is alot of amps that would work with those subs . with dual 4 ohm subs you can wire them up at 1ohm or at 4ohms. how much do you want to spend????

See:  https://www.the12volt.com/caraudio/woofer_configurations.asp

I would wire series/parallel for a total 4 ohm load, and use a two channel amplifier that will put out a bridged output of about 500 watts RMS into 4 ohms.

The alternative is to wire them parallel/parallel for a total 1 ohm and use a high current mono amp.  This solution will be the most difficult to achieve because most high current amps will produce much more than 500 watts RMS into a 1 ohm load.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

i would look at both possablitys i have found monoblock amps that are in that power range . are you looking to run closer to full rms power handling or are you wanting your subs to last a long time?

i have another question about the amplifier.  to power 2 subwoofers at 600 watts RMS will i need a 1200 watt RMS amplifier or a 600 watt amp?

If you want each sub to get 600 watts then you will have to use an amplifier that will produce 1200 watts into the combined impedance load of the subs.
