thanks a lot for clearing this up for me, my redneck friends don't know chit. well the rl-p 15 is definately an option for me now, especially since i'll only be getting one sub. the fi q actually was the other woofer i had in mind, but i really don't know how to make the decision because none of my friends even know these brands, let alone have setups i can hear. do most of you make your boxes or have a shop custom build it for you? i'm probably going to get a new vehicle soon so i can't justify the 350 they want for a custom enclosure. if i were to have a box designed around one of the subs, do you think home depot could do the cuts (i have practically NO tools)?
