Just got 2 10" SSD subs and I have a Hi Fonics Bxi1610D. I had both in my single cab Dodge truck, a friend of mine said that I could take one out and build a ported box for one and make it sound better that the 2 sealed. My question is, is that true and could I still use the same amp with only 1 sub? It would have to be either 1600 watts @ 1 ohm or 550 watts @ 4 ohms I believe since the sub is a dual 2. Thanks for the help in advance
