I originally got an Fi bl 15 fully loaded and a soundstream dtr 1700.1 the sub is a dual 2 ohm so i can wire it down to one ohm and get 1700 watts out of the amp. i just got a second one and i was wondering how i should go about powering it would the easiest and cheapest thing be to get another dtr 1700.1 and have both subs separate? another question i have is can the two subs be wired to 2 ohms or only .5 ohms and 8 ohms? Thanks
