Bo First of all thanx for subscribing to my thread :D. Participate there 2
Now coming to ur system. Ill go step by step
1) Pre is awesome , so is bt adapter , front comps.
2) Speaker amp is fine but 10k is a rip off price for it , its like 5-6k here
3) woofer amp needs to be changed asap for u to take true pleasure of bass
4) Most important point, 307d4 i am sure is wired at 8ohms as at 2 ohms it would make amp trip at bridge, where is 305c is running at 4ohm. This is not gud, ur 305c is under too much pressure
5) Hit me up with ur Trunk dimensions or when u visit islamabad, come c me, ill let u demo my torture chamber 
and get u a kik A$$ basstube and mb an amp aswell
Overall Its awesome, just make these tiny amends and ull b increasing performance by more than 50% thats my gurantee. i hope Brothers dont mind constructive criticism !
regards
