I have a klh asw120 subwoofer annd a pioneer receiver. the hookups behind the receiver has one output and the subwfr has a l & r input. does this need a y splitter or is there a certain way to connect this klh to the rec. i am also having a problem getting good bass sound off of it. is it better to connect it from the high level or just keep it a low level???

Yes, the 10-120 can use a L & R low level subwoofer input. You can get a short 6" RCA splitter adapter from Radio Shack for a under $10. (1 female input, 2 male outputs) Alternately, just plug the subwoofer output on your receiver to just the low level R channel on the KLH sub.

The left and right outputs from the receiver go to the left and right inputs on the subwoofer and then you wire the left and right speakers to the left and right outputs on the subwoofer....it is sort of what we calll daisy chained

I have the same amp. there a two ways to use it: The phono plug inputs are low level, are for use as an amplifier only, and their only output is the subwoofer output. In this case, any stereo satellite speakers would be driven directly from your stereo amp.
The high level inputs are meant to be driven as the same as speakers from your stereo amp. A circuit inside samples the bass and directs it to the sub amp and output. this same circut passes unamplified outputs to the satellite outputs. PM me at [email protected] if you need further info.

This is a pretty common problem with this sub.

Here's a solution that I posted earlier this year, including schematics for the upper and lower circuit boards. Be sure to check the circuit board revisions to make sure they match my schematics.

Yes if your sub will let you do that. It should work fine but it may decrese some bass from your two sat. sperkers.

Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...

Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
Low level input is only taking a audio signal from the amp. No power is being sen through the connection.

Hope this may help but you will disappointed. as heard from some pro, your amp will blow up the bose cube if direct connected to them, they are powering down your output to fit their tiny speaker. My understanding was you have to hook up everything to the bose module. They don't like to play with others.

how do I hook up the bose 901 EQ to a yamaha DSP3090??

In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs.
Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.

Is sub out turned on on the reciever? Some have a setting that doesnt use the sub out, like 2 channel.
