the amps got power but no sound???

[[[d a n n y]]]

i was installing a sub and amp today

i think i did everything right.

power cable earth cable etc etc.

the amps got power and all but no sound is coming out.

seems like the amps dead

i checked the wiring on the remote line and it seems to be ok.

what could the problem be??

MAybe it's your signal thats not getting through to the amp. Check the RCA's.

real stupid thing but if it a DVC sub make sure both your coils are wired the right way(both neg-neg pos-pos). I know it's a really dumb thing to say but i've seen it happen in the past. save that does your head unit have switchable rca jacks? some are switchable for amp out/aux in.

How do you know the amp is on? I'm assuming the light is on.

You should check the remote line with a test light to make sure current is running through it, although if the amp has a light this won't be an issue 'cos if it's on the light will be on.

If there is no light then a quick way of testing is shorting the power and the remote (so your power cable runs to your power on the amp, then just get a small wire and short the remote and power terminals on the amp).

Check the fade and balance on your head unit to make sure it's actually giving output to the amp. Check where you plugged the RCAs into the head unit to make sure you've used the correct output. If for example your headunit has a sub woofer output and you haven't enabled the sub then nothing will be outputted from those RCAs.

Check you've plugged the RCAs into the proper input on the amp, some can have more than one input so make sure if you've got more than one that the speakers/sub are/is actually plugged into the same channel.

Finally if you're bridging, enable the bridge mode if your amp has a button for it. Otherwise if you're not bridging make sure the bridge mode is off, if your amp has a button for it.

Check the wires on your amp to your speakers are correctly wired to the speaker, so the positive goes to positive and the negative goes to negative. Also make sure it's plugged into the proper wiring bank - sometimes it can get confusing there.

Good luck. Let us know how you go.

okay thanks for your help all

still trying atm

no sound or current from the audio cables

power going through

all wiring correct

would the output on the Hu be stuffed??

[jezzerrr]

sounds like somethiing is dead. should be straight forward. did you check the settings for the RCA outs on your h/u?

[ferni]

check for volts on the RCA's coming from your HU.. with music turned up you should be able to see a couple of volts or so on the RCA's

hm..

i may have found the problem

seems like the RCA output needs to be turned on??

but i dunno how to turn it on

cant find anything from the HU that seems to control it

those damn japanese HU

i think i might as well get a new HU

[jezzerrr]

try turning it off, and holding each button down for a few seconds as a start. pioneers at least have a settings menu that you access by turning off and holding a specific button for a few secs. That's if you dont really want to buy a new HU anyway

[ferni]

Check the back of the Headunit for a switch to output via RCA instead of line level (speaker) outputs.

i had the same prob with mine ... got the shits really bad ... i thought i f****d something but after a quick read through all of my manuals i solved the prob!!!

find out what h/u you have 1st then do a google search to see if there is support befor eyou toss it for a new one!!!

for pioneer hold the F key. that will brinf up a set up menu.

what unit is it?
