Amp Install, 1 Channel Not Working?

[white33gtst]

hey all,

i bought myself an eclipse XA4000 amp 2day. went to install it and it seems as though 1 channel isn't working properly? the car had a 4 channel amp in it already so all i had to do was swap over the amps. put in all the wiring etc and it seems the "left" channel dosen't want to work. whichever front speaker i plug into the left channel, it won't play at full volume. the other speaker will play at full volume and obviously drowns the other out.

is there anything else i can check? it definately seems like it is the amp. very annoying. it isn't settings in the head unit either because i disconnected the battery to install the amp. (settings reset)

so yeah... not h/u settings, not settings on the amp (frequency etc), i've swapped both speakers over and whichever speaker goes into the "left" channel it will only play on low volume. any help is appreciated.

dead amp..

mind you they tended to die quickly anyway.

Have you tried to swap the inputs?

From what I can gather you've swapped which speaker is on the output, but try swapping the inputs over.

yeah i've swapped RCA's over etc... swapped the front speakers onto the rear channels and they played fine. had the sub bridged on the front 2 channels, didn't want to work at all.

it is weird though, because i am sure all amps are tested before they are sent out for sale? unless damage is done in transit through rough handling?

i've taken the amp back anyway and explained everything to him. he'll get back to me monday morning. thanks for the help anyway.

just thought i'd update what's going on.

took the amp back and they hooked it up all fine so it isn't the amp. they had it hooked up for me to hear and everything.

i've just put my whole car back together it seems. ripped the rear seats out and checked wiring the whole way along up to the head unit. checked behind the head unit etc all seems fine. no wiring is loose or anything.

taken the left door trim off (since it's the left speaker not working) and checked wiring... all seems fine.

so, my next guess is the left front speaker is blown? i swapped the +/- over on the amp etc just incase i got them mixed up but no change in volume. i'm guessing this because no wiring is loose or disconnected.

any thoughts? they are pioneer splits, brand new from the same place. they were installed bout 2 months ago? they are the TS-C1625 splits

You said up top that you tried both front speakers from the left channel and they were both low in volume, so that means that your speakers are fine right?? The amp tested fine at the shop aswell, so it doesn't seem like they are the problems, its further up the chain.

Tried a different set of RCA's?

Maybe its your headunit RCA outputs, try running one RCA at a time to the amp (and split the one RCA into the two inputs on the amp, you'll need a splitter). Try it on left channel, then right channel and see if there is a difference.

hey

yer i had the same prob just last week all it was for me was the {rca} plug was stuffed so if u get a new rca plug and still not working try new speaker wire from your amp to your speaker cause there might be a short or wire is broken

so if still not working take it to a car audio sound shop

all fixed. was the RCA's. the rca's were plugged in wrong in the back of the head unit, so the place i got to install my headunit stuffed up. they mixed the non-fader up with the rear set of preouts, so the sub wouldn't turn up at all on the headunit. probably shouldve checked that earlier but i was more worried about the speakers not working properly.

thought i would get it all installed by a pro in the skyline because i didn't want to skimp out on the quality... obviously ill go back to doing all my own installs.

so yeah, i've switch that around behind the headunit and all works well. thanks all
