I have a BX1500d out of my buddies totalled car. I just got a new car so I don't know how big of a bix I can fit yet but would I be better off with a Brahma or L7 with that amp and which that much power how big of a box would I need? I'm going for SPL but I want it sounding somewhat good to a variety of music. I'm leaning towards a ported Brahma for now and then go to a 2 ported brahmas with one brutus per sub. Upgrading the electrical system and adding a battery or two more isn't a problem, but if I did that would it even be worth upgrading the rear speakers or just concentrate on the fronts? If you can't tell I'm preaty new to this stuff. Thanks
