Need something to power 2 gcons wired to 1 ohm. Only amp that will be running, stock factory bose door speakers/amp. Looking at the Orion xtr 1500.1 or the skar 1500.1 or maybe a soundqubed. Can I run 1500rms in stock electrical or is that too much? I want to run as much power as possible for them. Budget is $300. New.
