Will 250w RMS be ok for Alpine SWT-10S4?

[sweetchuck]

I have an Alpine MRx-V70 amp (5 channel amp).  The mono channel is 250w RMS at 4 ohms.  If I buy an Alpine SWT-10S4 and put it in a .50cu ft truck box, will the amp power it?  I know its under powered, but I really don't want to buy a new amp, and I've been scared of the sound quality to go with the 2 ohm version.  Thanks for any feedback.

Will it power it? Yes. Certainly won't hurt anything. No sure exactly what you mean by "scared of the sound quality to go with the 2 ohm version"

You will not experience loss of sound quality on the sub by running at 2 ohm, THD+N is rated the same at 4 and 2 ohms and you will be driving the sub closer to what it expects.

 

Honestly only cheap amps with deficient power regulation could perform worse when being used on a lower impedance load, Alpines is not the case, it could run hotter in any case if pushed hard, you prevent that with proper installation with great ventilation and maybe a fan nearby just to make sure if it became necessary.
