Hello,

i have problems with my 2 front speaker on my '90 zr1
i don't have any sound from them

ive read that it might be the amplifier and i've ordered some new one from ecklers

ive changed them and had to do some welding because new and old connectivity are different
on old connectivity, the wire are welded directly on the motherboard and on the new it has some "pin" that can be plugged and unplugged

unfortunately after all of this, ive plugged them and i obtain a repetitive "tac tac tac" from them

do you have some idea on how to fix this ?

Are you using 'Google Translate'? Syntax is bad on Google Translate...

Did you check to see if any power / signal is coming to the fronts, BEFORE ordering new stuff?

If there's no power / signal to the fronts, can I have your old [good] ones, when the new ones show from Ecklers?

i didn't use google translate

my english is that bad ?

It's probably the unit under the floor on the passengers side.

Call Dr. Don - he will get you all squared away. The years are different on the termination of the wires.

There is probably cheaper but Dr. Don does a fantastic job - 1 year warranty. He has done all the radios in my Vettes. It will sound really good when refurbished.

No - it's not bad English Dark Angel, but 'the Devil is in the details'...

Are you saying that you already put in the new ones from Ecklers?

Did you test the leads to each front speaker? Your multimeter should show a voltage increase as the volume is turned up...

DarkAngel as stated SCHRADE is right start with the basics make sure power is getting to the speakers/amps. As to your English it's better than my French lol and as SCHRADE stated we just want to make sure no details were lost in the translation.

If that checks out the radio brain behind the passenger seat on your 90 is the next logical suspect as stated by xlr8florida and Dr dons is the best choice for repair. GC

the front surely has power because when i start the radio, it makes "tac, ... tac, ... tac" from the front speakers

cvette98pacecar; great idea
i didn't thought of that
i will try to put the front speaker in the back and the back in the front next we to see what's going on

You do have some sort of power to the front but it may not be going where it should, thus the tac tac tac sound.

If your going to swap speakers rather than measure a few voltages then I'd
swap a single know good rear one to the front not the suspect front one to the rear since that is the one you modified.
You could avoid damaging the rear pre-amp depending on what the wiring error is (if there is one) in the front one.

1990 is different from 1991 thru 1996 - it sounds like they shipped the wrong part.

DarkAngel · 01-12-2014

when i had the car, the radio didn't work at all and it was the cdm that was not working
i've changed it and only the rear speakers works
the volume of the front speaker was between really low and nothing
but there was some noise; that's why i guess it could be the amplifier

i've ordered this part at ecklers

how does the part behind the passenger seat look like ?
