Loud Pop when powering up Radio ( might be just the back speakers )

anybody know why It might do this

doesn't matter what the volume is, or motor running or off.

faders works fine and the unit sounds good. Just the loud pop ( very loud )

ohya forgot to mention that it is a 1990 Allante

i believe that may be the pop of death.
the capacitors may be on their last leg.

if you are good with a soldering iron you can replace the caps,
also,
you can get them overhauled by BOSE directly - i think they also include new cones,
or for replacement exchanges, no new cones, you can contact allantesource.com.

thanks for the info. I guess you are refering to caps in the individual amps ?

 

[Stealth]

that would be correct ...

Your BOSE amp relay might be stuck on. I've seen this before, LOUD pop at key on. It is near the power antenna - middle one of the three.

how does one un-stick the relay?

i didnt even know we had a relay there.
is that relay on all year models?

thanks Stealth, worked like a charm... changed the 16 cap's in the back amps. Now they turn on with almost a fade to what ever volume is set at. Cost about $9 dollars cdn to do 4 amps ( with some extra caps, Bought 10 of each instead of 8...cheaper).

I found guides @ about 3 different sites, very helpfull.

 

[Stealth]

you are very welcome.

can you email / IM the location of those guides to me?
i am a full supporter of "interchange of knowledge."

thanks


note:
for those that dont know, the IM for yahoo is the same email address.
meaning, to the yahoo IM name, simply add the < @yahoo.com >
to get the email

I know this is an old post but hopefully some of you are still on this forum. A friend just bought an 89 Allante & it has speaker issues. I would like to replace the caps just need to verify which ones. I'm looking at the circuit board and I assume the 8 electrolytic caps(small round cans) on each board. Is that correct? I appreciate any help you can provide. Thanks -Kurt

 

[cadillac kevin]
