for my sister, She has a rf amp pushing 600 wrms and wants a 15 that will play loud in her eclipse and needs it to be under $200 . She is a volume master and is real hard on her subs so I need recomendation on a tough sub. I would like to put it in a sealed box so it may last longer.. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
