Is there any reason to use this subwoofer's L and R line level inputs, if I'm connecting to a single subwoofer Pre-Out on my receiver?

It's been recommended to me to use a "y" splitter to run the single out to both inputs.

I use only the single connection with mine coming from my Sony receiver and it works/sounds great.

Mono RCA cable. There are subwoofer-specific models available. You only need one channel for the subwoofer. The reason the subwoofer has a L/R input and output is to allow you to use the subwoofer inline with stereo pre-amp cables. Running the subwoofer off of a surround amp with a dedicated subwoofer output makes this feature unnecessary.

I don't know about "safely," but no, this is not what you want. If your receiver has a single RCA output jack for a sub, it wants to see an audio/instrument/signal cable, not a speaker wire/cable. If your subwoofer has speaker-level ins, then you want to connect them to the speaker jacks on your receiver with a speaker wire. If your sub has a single RCA-style LFE input, it wants to see a (shielded) audio cable, not a speaker cable, and it should be connected to the sngle sub/LFE output on a receiver. It sounds like you are trying to mix signal types here because your receiver doesn't have the kind of output that your sub needs, and you don't want to do that.

This would be for your sub output only. If you are not running more than one Alpine sub amp, you are fine with one level control. If you are running more than one, they will link together. Basically this is a subwoofer control only.

Yes, the output level is more than sufficient for a receiver's line-level input. In fact, that's how I use my Mpow. You don't have to worry about level matching on the Mpow as it is fixed. You would adjust levels using your source device. I would advise keeping the cable length as short a possible, however.

No. As far as I know, subs are always a mono signal. There should only be one output from the receiver and input into the sub. This sub has a second RCA jack, but I believe it's an output, and I assume that is for chaining. I just have a regular stereo RCA cable and I'm only using one side for the connection.Hope that helps.Adam.

I am using mine to connect two subwoofers to one sub-out on my receiver and it works perfectly. It should work for you to do that too.

No - "line level" outputs only, would need amp with line level inputs to connect to "unpowered" speakers.

No, no, no. If you have a one subwoofer rca out on your receiver, it goes from there to the left input on the subwoofer. It tells you this is your manual. enjoy

Dear Bill, Thanks for the info. I didn't connect the wire's directly but I guess it amounts to the same thing. The left and right front speakers are attached to STR-DH800 posts. I connected separate the speaker wires from the left and right front speakers posts to the left and right posts of the subwoofer. The subwoofer is a part of a Paradigm Cinema 70 set. It has its own power plug, an on/off switch and an RCA input The subwoofer hums when the RCA is plugged into it and I touch the unplugged end. Sincerely, John

Sorry, I'm a newbie at home theater stuffs, but why do we need a separate "subwoofer cable"? Won't the speaker wires work? I'm using a HTiB and they all use one type of speaker cables, even the subwoofer. I'm just curious as I'm about to get this system and have to learn how to set it up with a receiver. Thanks.

you hook this to your stock door speaker wires to give you the low output for an amp without high level inputs. so you would not hook this to the stock sub wires. it would go to regular speaker wires.

You will need one, two or three RCA type analog cables. So, depending on what you want to accomplish, you can connect the Subwoofer Output of the Receiver by itself with one RCA cable if you are connecting a subwoofer, or you can connect the Pre-amp Out for the Main Left and Right speakers (or other outputs), or you can connect all three at once, as all the inputs are active at the same time.

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.

Does the amp have a pre-out or LFE output? this sub does not have a speaker level input

Agreed with all of the previous responses. You want to simply control the input from one channel [A] of your amplifier, and that goes to your four sets of speakers, identified as 1-4 to the right of the input. Frankly, not clear why they are showing "Output" connections below the Input connections. I am sure someone knows, but, for me they are just irrelevant.

The high level outputs are just a pass-through from whatever source you're using to power the main or satellite speakers. The "crossover" only controls the max frequencies handled by the subwoofer (it's really a low-pass filter for the sub) and doesn't roll off the low end to the high level outputs.
