One thing to tell you "Spl for Life"
!
Don't worry We are brothers ,I am more inclined towards Sql and Spl
Yara do not sell 306c as they are extremely rare and best ever subs made by Pioneer
Man ,The Air pressure your setup made is out of this world ,Sincerely speaking can't ever listen GT-5 banging such hard before !
About Screen,Than don't use it anymore
Its of no use in your car 
More updates are coming and waiting for your single look on them
,So give Exams fast and come back to Spl
