Ininfity 1042W sub, need amp, which one of these ?

OK payday's tomorrow (actually late late tonight), so I gotta know right away.

One Infinity 1042W subwoofer, the RMS is 250W, maximum wattage is 1000, box will be ported, tuned around 32 .. 33 Hz.

Should I push it with an amp that puts out 75 percent of the RMS, say around 180-200 RMS ? Or should I go exactly 250 .. or should I even go higher than 250 RMS ?

Going with Profile amp, but I need to know which one I should get:

400MSX ... with 200W x 1 at 4 Ohm, 300 at 2 Ohm.

or the

600MSX ... with 300W x 1 at 4 Ohm and 410W x 1 at 2 Ohm.

In the future I may go with two subwoofers, two 1042W's, so I would just keep the same amp and wire it for two subs ? Or would I need a more powerful one to power two subs ?

Go with the bigger amp and it will leave a bit more room for upgrade at a later date.

Thanks.

So how far can I go, safely, as far as RMS for an amp, compared to the sub RMS ? Amp 300 W .. sub 250 W ... ok ... can I go even higher ?

Give that sub 300 and it will thank you. Give that sub 500, and it will stop working.

OK, thanks, guys.

So I take it running two subs would keep the amp the same way, just wire the subs ?
