@ Bro stj174 - I have just joined the thread today. Aap ko bachay ki bohat mubarak ho.
Your system is MashaAllah, the best I have seen so far.
Most people prefer to have SPL systems in their cars ... it is indeed fun to see every nut and bolt rattling in the car, but that is kind of murder of something as beautiful as music. I hope my words don't offend my SPL friends.
I have fallen in love with your system. The DIY has been detailed and exhaustive, and with sharing of personal experience, it becomes easy for others to follow.
