I might be asking silly questions. I am so interested to set my home system. I bought yamaha rxv673 and speakers pioneer c22, pioneer sp bs 21 and sub pioneer SW 8MK2. After I configure I can't get good output from my sub. Even I tried the test sound check the sub level is ver very low. I am not sure what mistake i am doing, how can I make sure the sub is fine?

If your receiver's YPAO auto-EQ program has set the level of the sub (in the speaker set-up menu) too low relative to the speakers, lower the gain (volume) on the sub itself and re-run YPAO.

If the level of the sub (in the speaker set-up menu) is within a few dB of the levels of the speakers, raise the level of the subwoofer by a few dBs. (Do not touch the gain - or "volume" - control on the back of the sub itself.)

Although there could be something wrong, it seems many peoples subwoofer levels are set too low for their taste after running automatic room correction programs.  Without the benefit of an SPL, I adjusted my subwoofer gain by ear, conservatively, before running YPAO, and it still dropped my sub trim level to -10.
