Ok for those of you that haven't read my recent posts I've bought a second car and I'm moving or building a system in it. I have a little over 4 net cubes to work with. I want to hit the low notes and my question is should I buy a good 15 or 2 12's? (I'd have to to sell my Idmax 10's ) to get 2 quality 12's. My other question is should I go bigger than the Ts 1.8kw I was planning on buying? Remember I only have a 170a mechman alt to work with.
