The sub is usually connected to a pre-out. This means the reciver isn't providing any amplification to the sub.

The sub takes the line level signal (which should be the same between the 235 and 335 if the levels arent set different in the reciever) and amplify it with the subs own internal amplifier.

Check the levels setting in the receivers and the gain/volume knobs on the subs, make sure they are equal. If so, switch subs- maybe one's blown?
