ohms?

[Budnik 10+ year member]

what exactly is the difference between different kinds of ohms? i know that ohms are the resistance of the current but like what do they mean. like does an 8 ohm sub not hit as hard as a 4 ohm sub? etc. all help is appreciated.

thanks,

matt

im not sure about the difference in how hard they hit but i know a lot of the ohms helps you have more ppossiblities in wiring the subs in parrel and series configs

This is the electrical resistance(impedance) of the speaker. It is the speakers opposition to the follow of current. A 4 ohm speaker will draw double the power of a 8 ohm speaker. The lower the impedance the more power the speaker will draw. There is of cousre a limit to this becuase the amp will shut down, blow up if the output is loaded to heavily. The reason that a 4 ohm speakers is common in car stereo is for effecienecy.
