Advice on connecting subwoofer with current setup

[hellonameismike]

If I have:

1. two unpowered in ceiling subwoofers
2. rx-v675 receivers with two pre-outs connection
3. an amp from Dayton APA 150 with a L and R inputs

I want to be able to power the in ceiling subwoofers a little without having the ceiling shake too much. I don't really care much for the heavy base, just a little.

Scenario A: How or what is the best way to connect these? Do I just use one preout on the receiver and connect it to the L in put on the amp and set the amp to mono. Then connect the two in ceiling subwoofers to the output with the speaker cables?

Scenario B: Or do I use both preouts and connect them to the L and R on the AMP and set it to Stereo or Mono.

Scenario C: The other option also I was thinking is maybe drive the in ceiling subwoofers by also connecting it to the Front speakers to the amp and use the low pass freq to filter out the highs? Can I connect them that way? with front speakers and another set to the amp to drive the woofers? would that damage the receiver or any other settings for this (LARGE or SMALL)? In this scenario, I am thinking I can drive the two ceiling speakers with the low freq but not too much and then also use the second preout connection for a powered subwoofers on the floor?

Can someone offer advice on the best setup?

My goal only is get some mild base with the ceiling woofer but not so much where the ceiling would shake.

I am new at this so any detail advice or explanation is helpful, especially with connections and settings?

The woofer-speakers are the one from monoprice:

Thanks in advance.

I'm pretty sure that receiver has subwoofer outputs which use the receiver's internal bass management. Thst's what you would want to use instead of preamp outputs.

Connect the subwoofer outputs (or use a "Y" splitter if you only have one) to both channels of the 150 and send the individual outputs to each subwoofer.

simple, safe, and efficient.

The Monoprice's are not InCeiling Subwoofers

If I have:
1. two unpowered in ceiling subwoofers (not accurate, see below)
2. rx-v675 receivers with two pre-outs connection
3. an amp from Dayton APA 150 with L and R inputs

I want to be able to power the in ceiling subwoofers a little without having the ceiling shake too much. I don't really care much for the heavy base, just a little.

1) The speaker at the link you provided is NOT an in-ceiling subwoofer
- A bad idea with many poor implications for your home to begin with
2) Rather these speakers are near full-range in-ceiling speakers (spec'd at 50-20K Hz) and just have a woofer for regular old bass response
- In your defense; Monoprice marketing poorly labels this speaker as a "sub woofer" with a "super woofer" (WTFO); in reality it is a normal in-ceiling speaker with a dome tweeter, mid range, and 6.5" woofer
3) A subwoofer works the frequency spectrum below ~100Hz down to near, or a bit below, 20Hz

Scenario A: Do I just use one preout on the receiver and connect it to the L in put on the amp and set the amp to mono. Then connect the two in ceiling subwoofers to the output with the speaker cables?

No

Scenario B: Do I use both preouts and connect them to the L and R on the AMP and set it to Stereo or Mono.

You can do this, but set the AMP to Stereo to use the capability of these speakers

Scenario C: The other option also I was thinking is maybe drive the in ceiling subwoofers by also connecting it to the Front speakers to the amp and use the low pass freq to filter out the highs?

?? Do you have some other speakers you did not list above?
- The option you describe here is not clear at face value.
?? Where are the in-ceiling speakers located in the room and in reference to any other speakers and/or a Home Theater display?
- You also have the option to connect the in-ceiling speakers directly to the speaker outputs on the rx-v675.

My goal only is get some mild base with the ceiling woofer but not so much where the ceiling would shake.

I also have 7 other speakers hooked up to the receivers in a 7.x theatre setup. The .x not so subwoofer is setup: one in the front between the left and right front speaker and another not so subwoofer in the back in between the back left and right. I know these subwoofer won't give me the same base as a powered floor unit. But I just wanted a little thump rather than a mind blowing one. I was thinking with scenario three I can have the smaller base on the ceiling and at later time add a better one floor base? Or recommend something else? What do you guru think is the best without going through how f up the setup is? Because the holes have been cut.

In ceiling subwoofers can be great, but you will need to do your homework to put them in and that little pea shooter amp won't drive them. You're looking at an infinite baffle build. I"m not an expert on these, but at least I can point you in the right direction.

I am not exactly sure what direction you are pointing me too and not everyone has an infinite amount of money to build a non baffle box. We work with what we have not someone's ideal system or specs.

Well, what I described earlier will allow you to play those speakers but, as others have pointed out, the results will NOT be what you're hoping for, particularly since they are not desighed to be subwoofers.

For what you are hoping for, you need to rethink this and be prepared to expend a bit of cash.

Consider this: A workable powered sub (in it's own enclosure/box) can be had for what you are planning to spend on this amp/speaker combination. And, bass is non-directional.

Thanks all for the replies. One last question, would it damage the receiver if I hookup one of the speakers that is rated at 6ohms along with say a center speaker rated at 8 ohms? sort of re-purposing it or there is really no point in doing so? I manage to hookup an old sony subwoofer but trying to figure out what I can do with these two speakers to go along with the other 7 speakers.

I should have done more research before I ordered these speakers, cut the holes and installed them. I originally started putting recessed lights in and figured since I have the walls opened, installed speakers without doing homework.
