What is the best way to hook up 2 alpine type r's. Give me options for both types of speakers, two dual 2 ohm and two dual 4 ohm. This will be all hoooked up to a hifonics bx1505D amp. I wanna hook these subs up to a one ohm. i need every factor that plays in getting these subs to hit!!! Also does anyone know if a hifonics bx1505D is half an ohm stable??? If it is let me know how to do it. Thanks yall
