Tried another Kenwood powered subwoofer that I know works and had the same problem. I have a KS-908EX. The subwoofer is SW-38HT. I have tried the setup and it keeps reverting back to LFE level. How do I get the subwoofer to work? This is in step 3 of the setup for the speaker settings

Check the bronze-colored coil underneath the foam cover. Note whether it looks worn, burned, warped or distorted. This may be the cause of your sub sounding fuzzy or muffled, which means it needs replacement. Look at the fuse inside the speaker and test it if you know how. This is a likely problem that causes your sub to power up improperly, play sounds at about half the volume or intermittently fade in and out. If the fuse is discolored or shows a short, you'll need to replace it
usually subs have outputs 4 ur monitors however if ur sub is active @ ur monitors are passive then you need 2 connect sub 2 ur tape loop with rca connections,usually you use the send signal from ur reciever which would norm connect to ur tape input , if the sub is passive then u connect direct to speaker output on amp then monitors to the sat connections on sub
Yes. It needs to know you have a subwoofer or it won't send low frequencies out to one. Then you have to calibrate its level to match the rest of your speakers. Hit the SETUP section in the manual (available at retrevo.com).
Its hard to tell what you can or cant do without knowing exactly which kenwood amp you are using. Generally speaking though most kenwood amps are stable only down to 2 ohms. you will be better off just using 2 of your 12s wired in parallel- that will give you a 2 ohm load. There is a way to use all 3 simply by wiring them in series, it will end up giving you a 12 ohm load on the amp though which will work fine but you wont ever achieve the full power that the amp can do.
It sounds like the input gain on the amplifier needs to be adjusted.
OR if your certain this hasn't changed see if both of your RCA cords (Left and right) are working. I had a similar issue when the mono block AMP was only sending signal from the left channel to the amp which in turn was dropping the input load in half. Its all about isolation.
Simple way to test this is to adjust the L/R balance of your deck all the way left or right and see if the amount of bass changes. If you balance all the way left and you lose your base completely then you know your amp isn't getting signal from the left channel thus if you move it all the way to the right and the bass disappears then the problem is with the right channel.
You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.
Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.
