No volume on all left side speakers


Determining the Cause of the Problem Let's assume our system has a head unit, a crossover, a two channel amplifier and two door speakers with only the right speaker working (the left speaker is not working). If the door speakers are behind the door panels then we want to make sure the speaker is the problem before removing the panel. We'll work backwards starting with the amplifier and ending at the head unit. Testing for a Speaker Problem With the vehicle and the stereo turned off disconnect the speaker wires for both the left and right speakers at the amplifier. Now connect the left speaker to the right amplifier output (which we know works). Turn on the stereo system and make sure the balance is set to the middle position.If the speaker still doesn't work then the problem is somewhere between the amplifier and the speaker Testing for an Amplifier Problem Now we'll need to see if the amplifier channel is bad. Put the left speaker back on the left amplifier channel and the right speaker on the right amplifier channel. This returns the speaker wiring to its original configuration. Again, with the vehicle and stereo off unplug the RCA cables from the amplifier's input and switch them so the left cable is in the right input and vice versa. Turn on the stereo system. Testing for an RCA Cable Problem For any intermediate components between the amplifier and the head unit follow these steps for each one. We only have a crossover so we'll just do this once. Begin by testing the RCA cables between the intermediate component and the amplifier. Unplug both RCA cables from the intermediate component's output. Now plug the working channel's RCA cable into the non-working side of the crossover. In our case the working channel is the right so plug the right RCA cable from the amplifier into the left side of the crossover. Turn on the stereo system.
If the right channel continues to work then you know the problem is in the RCA cables between the amp and the crossover. esting for a Crossover or Equalizer Problem At the input of the intermediate component (in our case the crossover) flip the RCA cables around (left to right input and vice versa). Turn on the stereo system.
If the right channel continues to work and the left channel continues to not work then you know the problem is in the intermediate component. Replace or repair this component.
If the problem is now in the right speaker and the left speaker works then the problem lies before the crossover. Turn off the stereo system and return the RCA cables to their normal places.
Testing for a Head Unit or RCA Cable Problem Pull out the head unit from the dash so you can access the RCA cables. Unplug both RCA cables from the head unit. Do not disconnect any other wiring. Plug the right RCA cable into the left channel of the head unit. Turn on the stereo system.

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..

How to I make it run at 2 channels, 2ohm per channel to get the 250 watts per channel?


If you are looking at the termianl side of the amplifier...you have on the left hand side a plus and minus, this will be the left speaker........the next terminals are the line in from thr radio head unit (RCA), then plus and minus for the right hand speaker. This is the basic setup for a 2ohm , 250W RMS output......please make sure to attach plus and minus to plus an minus on the speaker and not get them mixed around.....you WILL notice the difference

Front right speaker got wet, started cutting out. at the same time the rear right speaker started cutting. switched the rear speakers to opposite channels and this caused the right to work and left to cut....


the speaker getting wet will short it out. Shorting the output on any amp will ruin it. there is a right and left chanel with 2 outputs. Right chanel is damaged.

I am trying to install my xtant 604x after i just had it sent out and repaired. I have 4 rca's coming from the head unit wired to the amp as FL, FR,RR,RL. The front speakers connected to the front output...

As we agreed in chat - you are going to run your 4 channel amplifier as follows...

Front Channels of amplifier will run left and right independently.
Wire up the left speakers in parallel all + together and all - together.
This will yield a 2 Ohm load.

To the Same with the Right Side speakers - on the FRONT Right channel of the amplifier.

Now you have a 2ohm stereo load on the FRONT channels of your amplifier.

And using the BRIDGED nomenclature on the REAR channels of your amplifier - wire up your 4ohm sub mono.

Here is a crude drawing for a visual

How many speakers can I use?


Hi,
This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

Good luck

I recommend you swap your left and right input cables to make sure it's not a source issue.

So from your headunit, plug the left channel output into your amps right input and your right channel output into your amps left input.

If the same side is still not working then disconnect both (or single speaker if it bridged) the speakers from the not working side at the amp. Connect the front and then the rear speakers individually and retest to see if one of them works.

If one does work then check the cabling and speaker connections on the one that doesn't. If it's shorting out anywhere it will stop your amp from powering that channel.

Failing that, it could just be that your amp has partly failed.

Channel not working


If the Logitech Pulse 475 is the same as the Labtech Pulse 475 then the left channel amplifier probably blew. The Labtec uses a 5 pin TDA2030A, which costs around $3. You will need to know how to solder to repair this. The back of the case comes off by removing the 8 screws around the back of the case and lifting it out by the power cord. Then, simply desolder the left channel amplifier marked IC201 (it's on the leftmost side of the board, next to the volume potentiometer) and solder the new amplifier in it's place.
