Ok. My little brother has really been impressed with all the information and knowledge that I've relayed to him... of course, I give all the credit to this forum. So, 2 days ago, he just got his Kicker square L7 sub (15") - and he already sold all his old $hit (volfenhag 15", sony explode 15", power acoustik gothic series 1200 amp) because of all the new knowledge that has recently come to light for him and I. Anyways, he INSISTED on the kicker... so can anyone recommend the PERFECT amp and head unit for SPL at a half way decent price. I would greatly appreciate all of your help. He will too! Thanks, everyone. You guys are great!!!!!!!!!!
