Would this be able to run at 2 ohms

I am looking to get the new Alpine MRVF545 amp which is

125x4 at 4 ohms, and 250x4 at 2 ohms.

If i had 2 pairs of components that are 4 ohms, would I be able to run both of them at 2 ohms so I could get this 250x4 out of the amp?

come on...I know someone who knows this has looked at this thread...just drop a yes or no.

How do you intend to present that amp with a 2 ohm load with 2 pairs of components? Also, I don't think that amp was designed to run at that impedance on all 4 channels. If you did run it that way, you'd have to pack it in ice.

it wouldnt say it could run at that impedence if it couldnt. Esp. Alpine. Plus at 2 ohms I would run it light gain. I need just over 125RMS...and its exactly 125rms at 4 ohms.

2 pairs of components as in 4 mids, 4 tweets, and 4 crossovers?

If you did run it that way, you'd have to pack it in ice.

Why? If it is rated to output X amount of watts per channel @ 2 Ohms then why would you not be able to run it that way?

yes. I know I know "its to much" but im done screwing around with this crap...I have had so many different setups, none of which were loud enough for me, so im going to make **** sure this time it is.......BUTTTTTTT I am going to tryyyyy 1 set first and see how it sounds...But I want to get an amp that would work properly for 2 if 1 set doesnt work.

anyone....simple questions im sure. Little advice could help.

Umm different comps??? Go active?? 125w should be fine for comps... or how about bridging the amp down to two channels??

There are two ways to run it at two ohms and neither of them will send any more power to a set of components than you would by simply wiring them up each channel to a mid and tweet. One way would be to wire both sets of components to the fornt channels of the amp in parallel, presenting the front channels with a 2 ohm load. Each component set would end up getting 125W and the rear channels would be wasted. The other way would be to go with an acive setup and run all the tweets on the front channels and all the mids on the rear channels. Again you end with with basically 125W going to each comp set.
