Bose Amplifier

[DarkAngel]

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 ?
