can anyone explaine what is the 4ohms 2ohms in the sub and amp???
what is the difference within the two??
is 2ohms gud than 4ohms?

Basically, the nominal resistance in the voice coils of the speakers. 2 Ohms is half the resistance of 4 so amplifiers try to output twice the power, but will run hotter. They can also be damaged if they can't handle the load. Better amps can handle as low as 1 or even 1/2 Ohm.
Neither is "better", just different.
While many believe that impedance is the same as resistance, it isn't. A speaker does not maintain the 4 or 2-Ohm resistance when it is connected to an amp and music is playing. The "impedance" will rise and fall, largely depending on its design. If it falls too low, your amp may clip (distort).

That is the impedance (resistance) value of the speakers and/or the output of the amp. For best power transfer from the amp to the speakers they should both be the same value. If the speakers have a different ohmic value than the amp your hookup will not have maximum transfer efficiency. In other words you will have a power loss. It doesn't matter what the value is so long as they are matched.

Ohms are resistance to current flow, the lower the ohms the more current will flow, which means a sub of 2 ohms will be louder than 4 ohms when powered by the same source.

Ohms are resistance.
A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.
There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the resistance.

in sound quality:
4ohms is gonna be accurate, can hear the note a little better. not as loud but more accurate.
2ohms is gonna be loud and boomy. like an echo effect. its loud but not as accurate
look at it this way the higher the ohms the more accurate the lower the boomier.

yep 2 ohm subs will double the watts of 4 ohm subs. P=I x R
Power(watts) = I (current) X R(ohms).
Now that being said, you need subs and amps capable of handling this type of load or you will smoke something.
