I am trying to decide which one i should get. i would be hooking it up to two spr-50c speakers. Right now i have them hooked to the HU but its just not enough. Without an amp my two sub just over power them. When the subs hit i cant even hear them. So im fine on bass but i want nice loud highs and mids that i can hear when the subs hit. So which amp would be ideal for this? And whyy?
