please suggest me an av reciever with 160w rms at 6ohms in all 6 channels. I have a passive subwoofer. so the av receiver should have sub amp inbuilt. not planning to buy an active sub.
No one makes them anymore. Only the HTIB models come with a subwoofer channel amplifier. And for 160W RMS in 6 channels it will cost 5 lakhs+. You don't need more than 40-50 W for any normal room.
You better get a cheap AVR and a monoblock amplifier for the sub or just get a new sub since amplifiers are expensive.
