Hey everyone I got tired of searching all the old threads so I figured I would make you come to me. I have an 07 outback v with the standard kenwood speakers and head unit. I have upgrades the cabin speakers to the db-651's. besides that nothing. I want some tower speakers and a subwoofer. I dont really know what all I need to purchase to accomplish this task. As in what amb, should I buy a sub in a premade box, should I upgrade the head unit, what tower speakers should I get....? I would like it all to look nice. I was hoping you could give me some ideas. I am a novice when it comes to this topic. Thanks .
