Hey guys, I have an 07 Civic LX. I am getting my tax return next week so I thought I will upgrade my sound system with some of it.Lets say with around $600. My first priority is quality (but not too loud) not showoff but I should be able to turn it up once in a while and not feel bad. I have been looking around some websites for audio parts and saw pioneer FH-P8000BT and pretty much decided that as my headunit. Please recommend the other audio parts for me.(Yeah I need a somewhat good sub, amp if required) Thanks and appreciate your help.
