Dear Shankara.kris,
Thanks for your valuable reply, can you please share a picture of RCA y cabl setup, I don't have any idea about that, and yes first I will try to get it repaired because I like it too much because of the bass, Incase if I need to go for new one can please suggest one good sub with good bass (with this pioneer room/window will shake once I reach 50%of the volume, I like something with same bass)and I don't have much idea about cost I hope within 15 to 20k in mumbai, or new Bombay.
Thanks & Regards
Antony.
