I'm a noob so bear with me. I would like to have some trunk space available after i put my box in. Interested in a ported box I really want the 15BL but i am afraid it'll take up to much trunk space but i can settle for a 12BL if i need too. If i choose to go with 12BL or the 15BL, what dimensions and tunning spec so i go with? I listen to old school rap, trance and a little bit of alternative rock. Also which voice coil option should i choose to go alone with my amp? Current amp is autotek SS 1900 Thanks all
