Check the Sony book on the outputs for that receiver. THere should be a choice of regular speakers or subwoofer outputs. You used the wrong outputs from the radio. I may be mistaken...there may be only one set of outlets but there may be a selector switch in the radio that sets the frequency!

SOURCE: Change car stereo frequency from USA to UK

On many imported cars , the radios have options for different areas of the world (UK/EUROPE : ASIA  : USA+Americas  etc. )
 
If you have a MENU button  on your radio , see if you can find the Area choice option.
 
Once found , then it is just a matter of switching to the area required ( In your case UK/EUROPE)

SOURCE: hello i have a sony

Make sure you hold down the Bluetooth button for long enough. I found I had to hold the button for 20 seconds, until the unit entered Bluetooth pairing mode.

Sony mex bt3000p sub outputs dead?


You can double check by measuring the voltage on the outputs playing a 60Hz test tone at full volume. You should get around 7-10 volts AC. I have a 60Hz tone .Mp3 link on my site - http://sparky3489.webs.com/settinggainampclass.htm

I purchased a pioneer cd player for my wife's


I'm pretty sure it is referring to the rca (low level) outputs of the deck. This means you will have to use an amplifier to run a sub.

I have a sony HTDDW7600, i cannot get the dedicated subwoofer amp to work. The fan is running on it, but for some reason the only way i can get it to do anything is to unplug the cable that goes from the...


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
sources.
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
SML).
• 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.

Conncet a sony sub to a denon reciver


Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

MEX-BT5700U, no sound in speakers in CD source, tuner source OK.


What many people do on this model is connect the remotes wires improperly. Use the solid blue wire for the amp and the blue with white stripe for the connection to the car.

How to hook it up to system with two 10s 400 watts per sub and two 6x9s at 200 watts each?,subs behind seats, 6x9s in doors. IF i need another amp i have one,to help push. But either way i need your help...


Hello www_mitzjohn,

I'd definitely use another amp.

The 2-channel Sony is well suited for powering the 6X9's but a monoblock would be better for the subs. The different types of speakers running from the same channel will not sound very good and likely it'll be impossible to get the impedances to match.

You'll want to set the Sony to send higher frequencies to the 6X9's, but not to the subs. You can't adjust the channels individually. So, just connect each 6X9 to one channel of the Sony and use a monoblock subwoofer amp for the subs.

Hope this helps.

What is the wire diagram for the 3way bx35 boss crossover


Hello rew_smith,

The wiring diagram is silk screened right on the top of the unit. If your diagram is missing or obscured, you can get one directly from www.bossaudio.com.

The first 3 pairs of connections for subwoofer, front, and rear inputs coming from your receiver or head unit. Top is left channel, bottom is right channel. The 2nd set of connections are the outputs and matched in function to the first set. These are connected to your amp(s).

To the right of the input/output connectors are the 12V +, remote and ground screw terminals. The 2 switches and 9 controls allow you to set the high-pass frequency and output levels for the front and rear channels, and the crossover frequency, bass boost, phase, and output level for the subwoofer.

Hope this helps.

What do hpf and lpf switchs do


Hello rwalinske, The abbreviations "hpf" and "lpf" stand for High Pass Filter and Low Pass Filter. They do exactly what their names imply. They allow frequencies above or below a specific setting, while blocking or attentunating frequencies below or above the setting. There's also a "band pass filter" which allows frequencies within a specific range below the high setting and above the low setting. Finally there's a "subsonic" filter which blocks inaudible frequencies below the threshold of hearing. The hpf is generally used in speaker component systems to send the high frequencies to the tweeters. The lpf is normally used with subwoofer systems and is set to send frequencies below the setting to the subwoofer. While most amps will amplify a wide range of frequencies, they are more efficient when the range is limited depending on their intended use. For example, a typical 2-channel amp might have a frequency response of 20-20KHz. When used to drive a set of normal speakers, you would not use either the lpf or the hpf, but simply let it send all frequencies to the speakers. But when used to drive a subwoofer, and operated in "bridged" mode, the amp can put all of it's amplifying power into frequencies than can be used by a subwoofer if the lpf switch is turned on. Hope this helps.
