Hi, I'm trying to decide what to buy. This will be going in my daily driver. A Ford crown vic. I listen to all kinds of music (rap, hip hop, classic rock, metal, rock, etc...) Either way I'm using a Skar RP 4500.1 amp. It's between 3 dual 2 ohm Skar 12" EVL or 2 dual 4 ohm Skar 15" VXF. I'm going to be using the recommended ported box specs Skar gives. For the 12s it's 2 ft³ at 32hz. For the 15s it's 3.25 ft³ at 32 hz. Any help will be greatly appreciated. Thanks.
