Hello, I'm planning on building my first system and I am wondering what specifications I should get on my FI 15'' BTL. I want to get it to 1 ohm, so would I go with dual 1 or dual 2? I am going to buy an AudioQue 2200D, it is 1 ohm stable. I am going to do the Big 3 once I buy a new HO alternator. Any tips and/or advice would be greatly appreciated.
