Hey there....
I know you guys rock thats why i m here for help first thing :)....well the problem is one of my rear speaker has not bin working only have two 6/9 and i have a 5 channel amp but i ahve bin using it on three channel the speaker channels were bridged as specified in the user manual.Now suddenly one of the speakers have stopped working and i tried checking the channel buy plugging in the other speaker and there seem to be no current in that...I am just wondering what other checks i can make...to make sure the speaker is working ...but this is for a fact that there is no current in that channel .In the worst senario i will have to send it off to the supplier...cause its underwarranty luckily :) Let me know guys what you think and what check can made before i come to the conclusion that the channel is blown out...thanks

Best you can do is test that speaker with a known good channel on the amp. (Ie: reverse the amp output wires) and see what you get. Do this at low power too. If the "bad" speakers works, the amp channel has a problem. If the "good speaker" does not work, the amp channel is defective.
However, if the "bad" speaker does not work on either channel output... the speaker is blown. Hopefully the amp channel that powered it before, will work on the known good speaker.
Good luck,

also switch the rca's to check the input.

well i did that...there is no current in the Amp channel....Bad n good speakers are both working...on the known good channell....soo it has to be the amplifier channel then.Is this is Quite common to happen and why does it happen and what can be done to prevent this...thanks

well sounds to me like an internal part of that channel has blown out... assuming its a new amp less then 2 years old it is probaly under warranty if not then it would probaly be less then 100$ to have it repaired.

if you have an ohm meter this is the time to pull it out and test the impedence of the speaker at the amp to ensure it is hooked up properly, but it would appear the channel is gone.

Not an uncommon problem at all. The main thing you can check to verify that "bad" amp channel is getting a good signal off the RCA inputs. Ttocs mentioned swapping the RCA's and see what happends.
We now know your speakers are fine. Just need to insure the input signals to all channel inputs are there. The best way to test this problem is to either swap RCA's (L&R) or use a Walkman portable with headphone/RCA patch cable in place of HU RCA line.

PS Don't overlook the obvious either... check the HU fade and balance controls. Something that simple is enough to cause the problems noted or a loose HU RCA wire.

Still say grab a meter........... Check speaker impedences and reference to ground............

Good point... do that too!

i have the same problem but both of my subs work and i have power to the amp but not to the subs well let me know
ttocs on 11/16/2004 02:08:18
you just said the subs work, and they don't. huh?
swez on 11/16/2004 08:43:43
Different guy posting that his sub system is down.
Swez
PS Any progress on the original issue in this post?

i guess the RCA input jack of that certain channel must have gone bad.. cud be some other problem too..
get it checked by some local guy who does amp repairs..
comments...??
Victor...
PS. please let us have an update on your progress and difficulties.. so that we know wether u still need our help or have u sorted out the problem already...
