wierd problem

so i finally wired my system up...now i have a strange problem

after wiring up the 4 channel to run the 4 speakers...all would work except for the passenger front when running stereo...we put the wires into one of the other leads on the amp and it worked

then we put everything where it should be and it wouldnt work on stereo again but it all 4 work on mono???

could it be some kind of signal problem with the RCA's going to the amp?

Luke your post is uber confusing lol

what you need to do is test each part, RCA and SPEAKER

If you have tested the speaker that is not functioning on that channel, and found that it works when run on another channel, the its not the wiring or speaker.

Now you need to disconnected all the RCA's and take just one (1) of them and go plug it into each channel and make sure you get sound from all of the channels, that would rule the amplifier stage inside the amp being the culpret

if that checks out, you know its either a

Bad RCA
(cut, bent, broken, bad solder joint)

or Its...

Loose or disconnected at the deck

Take the deck out, and try the 1 rca trick again but going through all the rca outs on the deck, if that works than you have narrowed it down to a bad rca

simple steps for sometimes simple problems

ok...in simplest terms:

with the amp set to run on mono all 4 speakers work
with the amp set to run on stereo 3 of the 4 speakers work

that shows that it leads in the direction of a bad connection on the rca side, or bad rca, or bad connection at the deck, or blown output on the deck since in MONO it is summing both channels, so even if no input is coming off one of the rcas it will split up the signal from the other rca to both channels

connection at the deck is fine...

better not be the deck as i just bought it a few months ago (alpine cda-9833).

i'll try a new rca when i have the energy to rip everything apart again.

See if anyone has an RTA if you wana get serious...
or just by ear, personal preference, I prefere pretty flat response usually, unless Im in a bumping mood

just make sure your not clippin any of your signals on the amp, sometimes its hard o hear by ear, I double check with a scope

Luka..

when and if you're ready for someone to take a look at it for you, stop by..as per usual it costs you nothing for us to diagnose it and if it's a quick and easy fix that's gratis too, with the exception of any parts ya might need (membership service at it's best)

either way, everything will be explained to you before anything gets remedied
