Guys i had seen one ad in my company classified stating that there is a JBL GTO3501 amp for sale 350W. He says it is just 2 months used and he needs 3500 bugs for it. As far as i researched it seems like a Mono amp(Wht is a mono amp?). And its MRP is around 11000 bugs in rediff site. Is it a good buy???? Need to ICE my car as early as possible....
