sir aap nae tou tauheen kar dee amp kee zameen par rakh kar

i have also strongly advised you to upgrade electrical before going 1ohm...once electrical system is strong, it shud handle 1ohm really good too...
now get a good vented box to do justice to your type R. dont trap it in a sealed box. let it breathe.. 
@splfanatic....yar help this dude with a box. i have told him to make company spec box which is:
-2.9cuft gross
-2.2cuft net after displacement
-tuning 30hz
will sound clean, loud...and will give good highs as well as amazing lows 
wait i will try to sketch the box for u JZ!
congrats on the amp by the way
