U can get a decent 4.1 setup from Tech Com with a IR remote control for 2.2k.It has 1 year warranty nd is hell of the best for the money U are paying. Don't get fooled by big names. They are much costlier nd servicing is very difficult.

Ucan also consider brands like intex which is equally better nd cheap. U can get a 6000W PMPO 5.1 from intex for around 4k. It is much powerful than the TechCom.
