Hi, I have one of the above subwoofers. My headunit has preouts for a
subwoofer, (RCA jacks) plus the spkr. preouts. I'm powering my spkrs
with a 2 channel 800W amp. If I connect the RCA jacks from the head
unit sub preouts, to the - and+ on the subwoofer, and run 12V power
from the battery, and a ground, shouldn't I have sound from the sub?
The directions say to splice your - and + from your spkrs, to your sub.
Is this the only way this will work? I can control the frequencies from
the head unit. I would like to control the sub from there also.
Actually. I don't think you have to wire a remote switch from the radio to the amp on this product. This powered subwoofer supposedly has automatic signal sensing turn-on circuitry. I have the same problem. So I think I'll try to just hook up the power (to the battery), ground and the + / - speaker wires to one of the back speakers in the car and see if that works.
Choycemoon, that will work, that's how I did mine. I can control the
Low frequency, and the Bass from my headunit, which kicks **** bigtime.
You don't need a remote switch, to turn on anything. Everything will
power up when the key is turned on, and shuts off when it's turned off.
Hook it up just like you said, and it will work fine. Once you get it
hooked up, and hear it, just for grins, diconnect one of the sub wires,
and hear how bad your speakers sound. That little sub kicks ***! Can't
beat it for the $.

assuming that both subwoofers are working fine: check what voltage output your headunit has (RCA output voltage) and match it to your amplifiers input sensitivity (GAIN) eg: if your headunit has 4 volt outputs then on this particular amplifier your gain knob would be completely to the left as if in the off or 0 posirion.
if u are not sure of your headunits output voltage you could check the manuals specification page or send me the barand and model number of your headunit and I will check it for u.
hope this helps. let me know if I can assist you any further.
Hi there, the Pioneer VSX-815 amplifier only feeds out a mono LINE LEVEL output with the subwoofer signal. Therefore you would need to connect the SUB PREOUT jack at the rear of the unit to the "line level input" on a self-powered subwoofer.
Hope this helps..
Your kenwood only has preouts for a subwoofer. If you want to add the amp the amp will need to have some high inputs. If it does not then you will need to buy an accessory that will allow you to connect speakers and have rca outputs. From there yo will need two sets of rca jacks to run to the amplifier.
You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.
Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.

The red and white RCA pigtail leads is for AUX input

Right set of Preamp Outputs - Front Channels
Only Models C3433U, C3304U, and C3333U have a 2nd set of RCA pigtail leads for subwoofer output.
The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.
Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.
You can even now turn off your subwoofer / adjust the volume easily now!
