    i did swap the red one and the white one, but then the sound comes out from the left speaker, but the right one dont. i checked with the same cable into my home stereo and it works, so what do you think?? is it the HU??, is there any way to repair it any fuse or something??

    thanks a lot

It sounds like the preamp wire that carries the left channel signal between the HU and the 2ch amp has an issue. Here's two quick things to check.

  1. Check that both ends of the left preamp cable between the deck and 2ch amp is not loose or disconnected.
  2. Swap the left and right preamp connections at the amp. If the issue stays with the left channel, the issue is with the amp. If the issue moves to the right channel, the issue is with the preamp cable or the HU's preamp output.
Let me know what you find out!

    Definitely sounds like the issue is on the HU side of things. There's no fuse to change on the preamp outputs. The best you can hope for is that the left preamp output on the HU is dirty, loose, or has a broken solder joint inside, where the jack meets the PCB. Clean the jack as best you can, make sure it's not loose, and if you have to, open the HU and touch up the solder joint (which may not be easy to get to) with a soldering iron.

I have a kicker two ch amp and when I hook up my two 15s which ever sub I hook to the right CH flexes weird and don't sound like the one hook to the left CH


well what ampage is your amp ?? for example if its a 350 amp and you have two speakers at 200 each the sound quality will be **** in other words but if you have 1 thats 150 and 250 the less powered speaker is going to give out more sound. either that or one of the channels is broke or weak

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...


:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

Audiosource amp two intermittent distortion in monoblock mode


Good question, well constructed, a real fault report.

I would say from you fault description that maybe there is a dry joint / loose connection somewhere in the system.

So check all your wiring / connections.

Put the amp back into 2 ch mode and check each ch with the same source and load, do it both cold, and then drive the amp and do it hot do the shake test on both ch, cold and hot.

maybe this will help id the faulty area, if both ch have fault the it might be the psu as this is common to both sides.

If you can track down the fault to a or b then you can resolder all the connections on the board, if you are not happy with taking the lid off then take your amp with your test report to a tech, the test results may save you time and money.

Hope this helps, thanks for using FixYa.

Yamaha Dsp-A1000 5 ch amp Bought a used amp will be hooked to an awia reciever and speakers also have two subwoofers need help to install correctly witch connections to use


if you wanted to use your receiver as your controller and source then try to find out the receivber has got a bridge (jumper) between the pre-amp stage and the power amp stage. if your receiver does not have that, then you can just connect your receiver tape record out to one of your DSP inputs. subwoofers, the DSP has got a sub woofer out connector. you can use that (RCA type) to your sub woofers. put in series because DSP has got only one output for sub. or, you can connect your subs directly to the mains speakers, parallel connections. maybe one sub to your left and the other to your right channel.

Hooking up a new 8" woofer speaker to my amplifier


If I'm reading the amp manual right, you should be able to connect the amp in 3 channel mode. To do this:
  • Connect both left door speakers in parallel to Ch A Left.
  • Connect both right door speakers in parallel to Ch A Right.
  • Bridge Ch B and connect it to the new 8" sub.
  • Set the Ch A LPF/HPF to HPF.
  • Set the Ch B LPF/HPF to LPF.
This should allow you to run all 4 door speakers and the sub from the amp. It will also automatically route non-bass to the door speakers and "only bass" to the sub.

I have a pioneer gm-x404


The wiring is fairly straight forward. Along the top row of the ten pin plug =
(Left to Right)

Front Left positive,

Front left Negative,

Control wire from your stereo head unit should be thin blue wire sometimes listed as Remote Wire this switches your amp on and off via your head unit so you don't run your battery flat,

Front Right Negative,

Front Right Positive.

Bottom Row=(Left to Right)

Left Back Positive,

Left Back Negative

Centre Nothing

Right Back Negative

Right Back Positive

These are all inputs from your head unit.

To bridge from 4 channel to 2 you connect

one left speaker to Ch B Left Positive and Ch A Left Negative

one Right speaker to Ch B Right Negative and Ch A Right Positive

Ten Switching the Input Select switch to 2CH

Alternatively if your unit has RCA's on the back of the Head unit you can use them to run your subs.
Hope that helps.
