i just bought 4 rti38 ,1 csi30 and a psw 404 sub. love the system but my sub dose not seem to be able to handle to amps power. my receiver has a lfe output that i run around 80 to 100 hz. AT low volume the psw plays great. but when played at half volume it distorts and pops. the psw volume is at half also. my receiver is an onkyo tx rx-600. IS this typical of this sub or am i a bass hog?

shouldn't the woofer be able to handle what the attached amp put out?

Am I reading this right? You have the sub volume (on the back of the sub) set to halfway, AND you are listening with the receiver volume set to halfway?

Turn the crossover down to about 70, then turn the volume down, as I said above --

When you say your Onkyo is "halfway" are you exceeding 75 - 80 on the volume display? I would say that is pretty much maxed out for that particular receiver and you should not play your music any higher or you can clip out and damage your speakers.
If you are using the LFE make sure that all of your speakers are set to "small". This setup works best with the Onkyo.
You should also consider purchasing an analog SPL meter at Radio Shack for $35 and then adjust the gain on your sub so that it is the same "loudness" as the rest of your speakers. Try this as a baseline. Some people on this forum like to turn it down a couple of dbs from there.
Finally, make sure that your sub level output from your receiver is set to 0 db. Dr. Spec, who is known as the bass guru on this forum, recommends -3 db to 0 db max on the receiver level output for the sub.
One more thing, did you flip the phase switch on the back of the sub back and forth and listen for which one sounds better (better bass)?
