Ampflier only pushing one speaker

This has four outputs with about 22 watts RMS and four pre- amp outputs. So if you need to get the 5.1 effect an amplifier is needed to be connected so as to get the center ampflier and the subwoofer activated from the preamp outputs.
The amplifer on the DVD can be used for surround effect - rear speakers - as the front can be powered by the amplifier.
please check this interesting review

if you have an amp then you hook it up normal... left side + from amp to + to speaker... - from amp to - to speaker, and same for other speaker....

if no amp then i'm not sure your radio will push that big of speakers, but you would hook them up normal.... hope this helps.....

Looking at the specs for your system, the amplifier only puts out 23x2 watts. That means each speaker right now will get 23 watts (approx.). This amplifier is built to drive the load (the speakers) that is hooked up to it now. If you were to hook up another set of speakers, they would have to be pretty small (similar to what came with the system) with a higher impedance (over 8 would be good). The issue is the increased load/strain on the amplifier with the new speakers. However, if you are using relatively small speakers, with short run of speaker wire you should be allright (most amps have a temp protection built in, if the amp gets too hot it will shut off). To hook up additional speakers use the terminal that are there. You will 2 right speakers and 2 left. Place both positive ends of the right speakers in the positive terminal on the back of the amp (twist the ends together, if you must) and both negatives in the negative terminal, for the right speaker, on the back of the amplifier. Do the same for both left speakers.
In summary, you can probably hook another set up small speakers (which are only a short distance away from the amp) without much problem assuming you wont be pushing the amplifier to its limits all the time. You may find the amplifier lack punch or looses some sound quality though as the amp is not designed to be driving and controlling that many speakers.
Hope this helps

Connect one to each channel, for the best sound.

It sound like you have a break in the main wire from the computer sound card to your speaker amp OR the plug is not plug in completely plugged in all the way. Try some other speakers or ear buds / head phones to isolate sound card problem or speaker problem.

If you're saying you hooked the Bose speakers directly to the Yamaha's amp instead of the prescribed way through their own bass module - they're cooked.

They hook to the rear surround.

Well it should be like this...Your amp is prologic which means that it has 5+1 outputs (sub out may be for active sub).Connect your speakers on specific output for each one (center,front left,front right,rear left,rear right and sub).Other devices,CD,tuner...connect to the amp with signal RCA-RCA cabels.On the back of the amp you have all marked inputs.You wasn't specific what do you want to hook?!If you want to hook this "new" to kenwood connect rec out of it to aux in on kenwood.If oposite kenwood rec out to "new" aux in.Hope that this is what you need

how do you have your system hooked? What speakers do you have? There is a lot more too it then just wattage.
