I have a 4 door F-150 and am looking for a system. I recently purchased 2 10in JL W1V2 with a JL 250 watt amp in a custom box under the seat and they sound alright but I am looking for some brain rattling bass. I want everything to vibrate and wanna be heard by everyone at the stop light. Having some trouble finding the right sub especially for the all the open space in my truck. Any ideas??? preferably a 10 in sub so i can keep my box. Thank You
