Hello, just bought a new yamaha dsp-ax1 and i'm having a few problems.

1. The amp dosn't seem very loud, i have to turn it up over half way to get anywhere near decent volume levels. It does go really loud but only with the volume turned nearly all the way up. Is this normal for this amp ?

2. I'm using two Rel Q100e subs and the only way i can get them to work is by selecting BOTH on the LFE output menu, if i select SW nothing happens.

Any help would be appreciated

Thanks
