Very happy with the apsm2000 I switched out my subs (back to the duel 2s) and wired it in 2 ohm and left town on a 4 hr road trip. I ran damm near every song in the iPod with no problems whatsoever. Amp stayed under 100 degrees with not even 1 hiccup.

Great value if you are looking for an amp in this power range for a daily driver get one . I cannot speak for their other models but the apsm series seems to be a very solid amp. I am seriously thinking of buying another and linking them in 2 ohm. I wonder if the sa15's can take it??lol
