Hi. I have a Sony HT-IV300 home theater. I am getting low sound from rear speakers (5.1) (I also tried settings and resetting) both in Dolby pro logic (stereo speaker fill) and in 5.1 (from Tata sky +HD STB) so I think of adding an amplifier to the speakers. Can anyone give me a link of an amplifier which doesnt have USB, FM and extra things other than amplifying two speakers sound and solves the problem under rupees 500 or under $8 (ebay or amazon only)? Please. As far I searched I am finding one with USB, FM or something like a board. I want it like an amp. Thanks in advance 🙂
