RCA from stereo to amp not functioning properly.

The only way that my sub will output any sound is if I put either the left or right RCA cable into the output and the other into the input for the amp. otherwise if I put both into the input side the amp goes into protect mode.

Make sure switch on amp is on master, if it doesn't have a master/slave switch... turn your gain down.

SOURCE: amp is working and is putting out, but no sound from subs

Ay man I had the sam problem. What's happening is your amp is taking in too much power and too much heat. In my car I have a aduibahn amp that matches the box like yours. You should try turning off "bass boost" and/or "sub sonic" or "game" on your amp if it has those options. This will cause less heat and power and prevent your amp form haveing a terminal shutdown which is what Im confident is happenening. Also does your ride have AC? If not you should try letting your back seats down just to test it. Cause if your car is hot, then imagine how hot the trunk would be. If you need more help I got you at 317 374 7483 or tajcze@aol.com peace

SOURCE: how do you hook up a sub and amp to a stock radio

you can splice into the wires for your rear speakers and install some of your owns rca's and just use the low pass filter on your amplifier to eliminate the mids and highs from the frequency to your subs.

SOURCE: Stereo in my Fiat punto

Hello, when I insert a CD (normally purchased) into my Fiat Punto Grande stereo it displays "CD ERROR", ejects the CD then displays "AUX" (the tuner still works). I would be grateful if anyone has any idea what the problem is, thank you.

SOURCE: hi i trying to figure

Without having the exact model numbers of all your Pioneer deck and your Clarion EQ, what I can do for you is send you to the following website:

http://www.ehow.com/how_7207112_wire-car-equalizer.html

Once you get to the page scroll down to the link called AudioControl: EQX Owner's Manual. Download that pdf file. It is actually the owners manual to an EQX equalizer. If you then look at page 10 and 11 they show you a wiring diagram that will probably fit what you are looking for. Essentially what you are going to do is the following:

1) Wire the main output of your deck to the Epicenter unit.

2) Wire the Epicenter main outs to the Balanced Input of your Clarion EQ.

3) Run the Highpass connections from the Clarion EQ to your Tweeter amplifier, and then wire the amps output to your Tweeters.

4) Run the Lowpass connections from the Clarion EQ to your Subwoofers amplifier, and then wire the amps output to your Subwoofer. If you have two separate amps for two separate subs then wire accordingly.

5) If you are going to use your 4 channel amp to run your tweeters and your midrange speakers, then you would run the full range output of your EQ to the two channels of the amp that would be your main or midrange speakers. Then you would run the Highpass outputs of your EQ to the 2 channels of the amp for your tweeters, and then the ouput of those two channels would go to your tweeter speakers.


This should give you the necessary information to wire up all of your components. IF you need any further information then please don't hesitate to let me know.

Thank you for the opportunity to assist you in resolving your issue. Should you need further information or assistance please do not hesitate to let us know.

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.

How do i hook my car speaker and the sub and output converter together


you splice the output converter into the stock stereo speaker wires, then run rca cables from the converter into the amplifier rca inputs. the amplifier prolly has left and right speaker leads, you will have to locate a manual, or photo of the mono bridged lead position, if it isnt labeled on the side of the amp

How do i connect the sub to the amp and my flat screen


Typically there is an RCA jack on the back of the amp (assuming you have a surround sound amp) by the rest of the speaker connections. Run an RCA cable from it to the input on the sub. If you have a stereo amplifier instead of a surround sound amp you could connect it to either the left or right side of channel B, but it wont give optimal performance.

I have a stock stereo and two subs with an amp in the trunk. Also two alpine speakers in the rear. Whenever I turn my balance to the left my subs don't play. What's wrong?


Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

I need to know step by step how to hook up my entired system using my macki board. I have a Mackie 1604 Vlz, a power amp for mains, a power amp for subs, a crossover, a vocal effects processor, and a 16...


ok, first thing will be the effects processor. look for the "aux sends" output jacks near the bottom center of the rear panel. run a 1/4 inch instrument cable from "aux send" 3 out into the input on the vocal processor, and run another from aux 4, if the effects processor has 2 inputs. then, from the vocal processors output, run 1/4 inch cables back into the "stereo returns" on the mixer, (located on the rear panel on the bottom, extreme left) 2 outputs per input, since its making stereo effects. so, if you ran just send 3 into the processor, you should have a left and right return instrument cables into the mixer for "stereo return" 3 (left and right). if your processor has 2 imputs, and you are using both "aux send" 3 and 4, then you will have to have a pair of cables going to each "stereo return" for 3 & 4. -to apply effects to a microphone(s), you would adjust the individual aux send levels for each channel you want to have effects, and you would have to ensure that the master aux sends and returns are also turned up..

ok, the snake is simple, each xlr (3 prong mic) connector on the snake is labeled, so, just plug each xlr jack into the corresponding channel on the board, and plug the first 2 1/4 inch ends of the snake into the "C/R out balanced" outputs on the board, located on the rear panel, up and to the left a bit.

at the stage end of the snake, ues a 1/4 inch instrument cable to copnnect the first 2 1/4 inch jacks on the snake to the left and right inputs of the crossover. then, from the crossover, connect the sub power amp to the "low" stereo outputs of the crossover with instrument cables, and connect the main speakers amp to the "high" stereo outputs of the crossover with instrument cables. if its an adjustable corssover, you will want to have it crossed over somewhere about 80-120 hz to allow only the lowest frequencies to the subs.

now, from the amps to the speakers, we ane going to have to use heavier 12-14 gague SPEAKER CABLES, instead of light gague instrument cables. hook the subs up to the stereo speaker outs of the sub amp with speaker cables, and do the same for the main speakers.

Hi i have just bought a alpine dvd headunit the 105r and it only has 1 phono sub output and not the left and right phono output how do i connect my amp to this


it has 3 pairs of rca outputs, one pair for the front, one for the rear, and another for the subwoofer. the other sub preamp output is not needed to run to your amplifier.

For better sound quality, buy an RCA Y splitter cable (single male connection to double female connections), and run your regular pair of rca cables to the amp.

Connecting a car stereo to an amplifier


you have to connect your 4 speakers to 4 speakers output direct to your car stereo no need of amplifier to 4 speaker but speakers should be small not like a woofer, and you have to connect your sub woofer by using amplifier don't connect direct. connect the output of your car stereo (using 2 RCA) to the 2 RCA inputs of amplifier. If u connect your 4 speakers to your amplifier then your car stereo does not support Left Right channel.
You can also connect your laptop or iPod direct to your amplifier.
Good Luck
enjoy music

How do i connect my pv2600amp to my peavey subs and top speakers, i have the leads but what do i do?


Line outs Left and Right from mixer to power amp Left and Right inputs,
Power amp outs to Subs(if they have passive crossovers built in check specs on subs).
From Subs then to Main spkrs. Make sure power amp is set in stereo mode using this way.

Alternative: You will need at least a 2-way stereo crossover unit inline after mixer and before power amps if the subs don't have a built in passive crossover. Most of them do have passive crossovers in the subs these days. Then separate amps or one channel would drive the subs and the other the main speakers. True stereo would require at least a 2 way crossover and two stereo power amps if hooking them up this way.

There is another option as is common with many sub setups. Send the signal to the mains using L/R outputs from mixer and a separate Mono output to the subs only. Putting only bass/kick and low frequency outputs in this send would help too.
