Dahlquist Subwoofer installation

totally lost on trying to get a Dahlquist Subwoofer installed with my Marantz 4270 receiver. I hope someone can look at the information below and try and walk me thru the installation process. (I do not know the model number of the subwoofer)
the back of the unit has the following (as well as the power cord)

a) 4 squares for your L and R speakers (In)
b) 4 squares for your L and R speakers (Out)
c) 2 RCA inputs (female) listed as L and R under the heading: Low Level In
d) An on/off knob for Crossover Frequency. the minimum reading is 50, and the maximum reading is 150.
e) one very small switch that is under the heading "Phase"
(when the switch is in the "up" position, it is on 0, and when it is in the "down" position, it is on 180.
f) another very small switch that is under the heading LFE. this is an on/off switch
g) a volume control knob

just looking to see what I need to get it hooked up.

thanks

Hi - Correction - I think on LFE, that may be the direct input from a surround sound processor that is sending out video-track LFE - Low Frequency Effects - again pls double check in your manual.

thanks for the info. I did all that you said, but now I am wondering if the sub even works. I hooked all the speakers up by running them through the sub, and all the speakers work, but the sub does not work. Remember, I am trying to play this with an intergrated amplifier. (I have tried both my Marantz 4270 and my Pioneer SX-1250.) Neither of these has a "subwoofer" outlet. Do I need some sort of Pre-Amp?

Hi R...

if the sound signal is running thru the sub and then from the sub into your speakers...then the sub is [partly] operating otherwise the signal would not carry thru the sub to your speakers.

However, i think you may need to check that the sub itself is playing bass. To keep life simple...

...focus on making sure the RCA-outs from your integrated (OR the speaker outs from your integrated) are correctly connected to the sub.

....Crank the sub and see if ANY bass comes out of it. Play with sub volume (turn it up)...and play with crossover...does any bass or music come thru at all?
