The manual says not to use preouts at the same as speaker connections even though the same signal goes to each. I don't want to run the speaker wires through the sub in case I degrade the signal. Looking to changing my fronts to large by doing this so they are full range (speakers go down to 47Hz and sub to 20Hz). Thanks.

Re: Can I use front preouts for subwoofer?
First, you have to have a self-powered subwoofer (or two) with this reciver. That means the sub has its own amplifier. These are usually capable of accepting either Line Level (RCA) input or direct L and R amplifier channel speaker wires from your receiver from which it will react only to frequencies in its range. It doesn't actually use any if the power from your receiver's amp.
That is why you can extend your front speakers from the sub. Again, understand this - it is not playing any part in amplifying them. The amps in your receiver are just passing through it.
Setting your speaker 'Type' definition to Large will tell your receiver that they are capable of real bass (as opposed to small satellites) but won't necessarily steal anything from the subs. Set your LFE/Bass Out setting to Both if your front speakers are capable of handling real bass. Why would you want to deny them bass if they can handle it?
This part is confusing "If I can get the sub working on taking the lows out of the front speakers if I set them to large on the receiver then that is one thing less to send to the other sub on the LFE channel". The crossover feature allows you to define what bass goes to the sub. You would use the various points to smooth out the transition between your sub and the rest. Your quote of 47hz spec for something doesn't suggest your other speakers are great bass reproducers. One needs to see the +- db spec with less than x% distortion for that number make any sense.
Your receiver has two RCA Subwoofer Outputs but I'm sure they get the exact same level. If you're having trouble matching two different subs doesn't at least one of them have an adjustment for volume? Or maybe you could use physical positioning to adjust their comparative volume.

The Jensen JS650 does not accept line level input so you need to use the Front B speaker output from your Sony receiver and not the RCA subwoofer output. Even though your subwoofer is active, it does not support line level (RCA) signals.
Just connect the subwoofer as you would a pair of speakers. Once connected, you make sure the front panel speaker switch on the Sony is set to A+B so you get sound from your existing speakers (A) and subwoofer (B).
H?, You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer. .your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while
you are switching the modes of the surround you will see the speaker
position on the display of receiver as well..if you do not see the sub
woofer it wont be activated..Sound Field Program (A.F.D) is a good
example to test it.. Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps! -------------------- Additionally please follow the instruction on your user manual to activate the SUB ,as is follows.. ----------------- BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.
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..
Hi, just turn up the gain, though the max voltage may be higher, it does not mean the audible output is higher, alpine decks subwoofer control is an attenuator, so at max it will be the same level as front n rear, on min it is -15db... you will probably find the kenwood is +/- 7db so it has a gain boost...
just crank up the amp gains, problem sorted...
1 Use MULTI-CONTROL to select SW CONTROL. 2 Press MULTI-CONTROL to display the setting mode. # Press BACK to return to the previous display. 3 Press MULTI-CONTROL to select the segment you wish to set. Press MULTI-CONTROL repeatedly to switch the segment in the following order: REAR SP (rear speaker setting)—PREOUT (RCA output setting) 4 Use MULTI-CONTROL to select the desired setting. Turn to change the setting. When REAR SP (rear speaker setting) is selected. REAR SP:SUB W(subwoofer)—REAR SP:FULL (full-range speaker) When PREOUT (RCA output setting) is selected. PREOUT:SUB W (subwoofer)—PREOUT:REAR (full-range speaker) # When no subwoofer is connected to the rear output, select REAR SP:FULL.
The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
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.
