Well yes! I would rather have a really good 2 channel amp for those 3 subs. To be honest that amp you got is kinda cheapo. Im sorry if your hurt but that but it's the truth. That amp is gonna give you no more then 150 watts per chan. And your subs are rated at much better then that. If I where you I would have gotten a 2 chan amp and wired it up to those subs. Good luck.
