So Im still breaking in my Cvr due to warranty repair and I have it in a ported box. Problem is its a D4 and im running it at 8 ohms, which my amp puts out 375@4ohm n 750@2ohm so i dont think im running much power 2 it. I listened to my bro's D2 cvr wired @4 ohms and it got really loud for jus one sub. Im really wanting to know if it would be safe (or smart) to jus wire my sub for 2 ohms n tune my amp to the rite rms, idk if this works or not.
