Question about 4 ohm speakers The speakers I want are 4 ohm speakers, and the amp I want is rated at 100X4 @ 2 ohm and 75X4 @ 4 ohm. So does that mean I have to find 2 ohm speakers to get the full 100 watts?
Here's the amp...

Don't worry too much about the difference in volume between 2ohm and 4 ohm. It is Barelly noticeable (if you can hear it) and adds distortion by around a factor of 10x.
Also, the ouput specs for the rated ohm's are using Static resistance (think resistor) and don't take into Account the True nature of Speaker Dynamics.

Look at the Curve on the Left. It shows the natural Sweep and not the Linear reponse you would think. Ohm's for a Speaker is an Average measurement.
So, All said and done, Just go ahead and wire it up for 4 ohm and you'll be fine.

I figured id be fine if I wired for 4 ohm, but what im saying is, that amp will only push 75X4 @ 4 ohm, right? I basically want my music as loud as possible.

Hes just saying to stick with 4 ohms because 25 watts wont make that much of a difference. Hes right but if you MUST get a 100watts cause you just want it then buy a bigger amp.
