So at the moment my car has installed an almani pa900.2 Amp, and a pioneer 3001d (1000 rms)(these came with one of my cars so i put it to use) and im eventually installing my Alpine type R's (1000 rms as well) to a sounstream 2000 watt amp (1300 rms split into 2 subs). Now my question is, even thouigh the soundstream amp will under rate these subs, if i used my type R's one at a time on my amani amp to break them in, would this hurt them? Ibviously 750 watts is underrating them, but i feel like 450, or even 250 which i think is what im pushing could be more harmful if at all.
