May I use this to add a subwoofer to an old 2 channel receiver? Receiver only has 4 speaker level outputs (A&B).

And the answer is YES. Sorry for the wait, but I had to wait for the reply from my GEEK friend who installed this item.

I dont think so...This amp is not work for Sub....only small out put 2 channel and will be work on regular output.

You cannot do that. This module will work with only on subwoofer. Second sub demands another separate module.

Although it would work, best results would be achieved using another amplifier of at least 200 - 600 watts per channel. In this application a better choice may be to purchase powered subwoofers.

Any subwoofer occupies a single "channel" from the receiver - one that combines the low bass outputs from right and left channels. Thus, one standard cable is usually sufficient. Do check the rear panel of your receiver/home entertainment power unit. It should have one output receptable labeled "subwoofer" or something similar. That is where the plug from the speaker goes. Since bass frequencies are not localized by our ears, there is no need for 2 subwoofers or separate cables to connect them. If the subwoofer has separate input jacks for the right and left channels (labeled and usually color coded) - which is very unlikely - you would need two such cables, plugged into the auxiliary R and L low level outputs from your receiver's pre-amp outputs (labeled)!

This device only has two output channels, so some form of separate crossover would need to used from the outputs. I think adding components like that would defeat the purpose of buying a simple stereo amp like this, though. I'm using mine to drive left and right speakers which themselves have separate subwoofers built in to each of them, although there's no crossover circuitry; it's just two sets of wires coming out of each speaker. I put the subwoofer wires into the same amp output holes as the main speaker wires, so I'm not actually getting a discreet sub channel. I'm sure the EQ is way off, but for my purposes and at low volumes, it's not essential.

Short answer is yes. The signal goes out of both the high and low outputs together. I tried it. It worked but I realized to get enough volume to the sub to make it sound good, you were distorting the power to the speakers. They were also really drowned out by the sub. My recommendation and what I ended up doing was to get a 4 channel amp, bridging two channels for the sub and using the other two channels for the speakers. With the amp crossovers, you can really dial in the sound and get the best bang out is the sub. Good luck.

Only if you receiver has the capability for a split sub-woofer system. If it doesn't you could split the single channel so that you have two center-channel sub-woofers located in different places.

This amplifier requires a preamp, or existing receiver. If your subwoofer is powered, you will have to use the preamp or receivers subwoofer preout. If your subwoofer is passive, you can sent the signal to the amplifier but will not be able to run a true 5.1 surround

I would suggest NOT. This device is used only for multiple speaker distribution from one amplified source. I am not an "ee", but the reverse logic (4 sources to one speaker source) may appear to work, but you may cause harm to the other sources depending on how the sources were designed. I am not certain why you would want four receivers input to the same system, unless you are operating a store. You should consult a local expert if you are certain you want to do this.

It already has a low-pass filter, a separate sub volume control, and a separate x-over control (50 hz to 200 hz). Also there are 8 speaker outputs. The top four are left and right (2-each) and the bottom four are 4 wires to the subwoofer (2 + and 2 -). I imagine you could use it for a subwoofer only - just don't use the left and right channels...

You don't say how you want to add. Assuming that you want to connect to the subwoofer, check impedance on Acoustimass speakers (from specs). If same, then probably yes. Did you call Bose customer support?

you probably needa Y jack to do that and they sell them all over. I would not try that tho until I contacted the manufacturer to see if that can be done. If they are both powered by amps then they may conflict with each other. Only a manufacturer can tell you that. A Y jack would work but you have to make sure your impedance levels match. I would contact the manufacturer to be safe. I would hate to see you blow the subwoofer out.

hi, i don't think is going to work, the output for the subwoofer should be without power amplification, and is usually a dedicated output, if is not there, your amplifier is not designed to connect a subwoofer. sorry.

Yes. All modern receivers I know of can be used with just two front speakers or additional speakers in any sensible combination, up to their maximums.

It would depend on the amount of speakers you are hooking up and the wattage I have a four channel personally but have it set to only power two speakers so If I decide to upgrade my system again I have the ability to do so

You can probably get away with just the one rca out, but you should go to the Polk website - they have a lot of technical info there on connecting a subwoofer in your system.
