I have a Technical Pro IA-S750 and when I have it on any of the channels I get a garrgled sound coming from the subwoofer and I can't get it to put out the bass to the song that's playing. Is there any way to fix this?

i dont know if amp has fuse for each channel, but they would be easy to see.. otherwise that baby has a blown component or two on a pc board, maybe an output power transistor of capacitor failed.
Last time i went to a shop it was like $100 plus parts for a similar repair.
I recomend sending Sony support an email and see what they say before you take it anywhere as well..
If the amplifier itself is making the popping sound I suggest you disconnect it immediately, as it could be an electrical short within the amp. If the popping sound is actually coming from the speakers, it could be due to a crossed wire, blown amp channel, or blown speaker. If you posses the technical know-how, you can test the amp channel and speaker by connecting a different speaker to the channel responsible for the popping sound. If the new speaker makes the same popping noise then it is most likely a blown channel. I hope this helps =)

Well let me first ask is the center chanel working? or properly hooked up. Cause most of the times when in 5.1 the talking or "dialog" as you put it comes only through the center channel its just kinda how they do it. Listen to see if the center channel is working. if you are unsure try hooking up a speaker that you know works into the center channel speaker output. If no sound comes out then the reciever possible has blown its center channel. Please follow up with a comment and i will be glad to assist you further thanks, Midwes-tek
Yes, you are right. This receiver is rated at 100WRMS output in all 5 channels (2-front, 1-center and 2-surround) while in Dolby Pro Logic operation. The subwoofer output is line level only (not amplified), which means you need a powered subwoofer to be connected to this output. A non-powered subwoofer could be used but, you need an additional amplifier connected to the subwwofer output from the receiver to drive it. Let me know if this helps.
