so you are not using the built in amp in the ipod/iphone= better quality audio
but for just testing you can use the headphone out
you just want to know is the sub working correctly or not
if it sounds just as low, then the issue is with the sub or amp
if it sounds great then its probably the LC2i
So I checked with the iPod. Seems that I can go louder with the sub at the same setting. With the iPod turned all the way up and the amp at the 9 o'clock position, it does seem louder than before.
