Default Woofers

last winter i had a Kenwood installed, and upgraded the tweets to a better solution. I noticed
the last cpl days the woofers are not working.. not sure how long this has been going on, I have the fader set to 75% rear and lots of base there.. so never noticed none in front until today. the Bose fuse is good, the relay is good. wireing is good and still connected. the woofs are good, I have run out ideas,, When adjust the fade to full front, left and right, all is there is the tweets.. any thoughts or ideas be appreiciated.

1. Radio amp trigger not working. Check for 12v at the blue/white radio wire.
2. Adapter not triggering the amp to turn on. Would have to check for voltage at the amp in the door.
3. Both amps in the doors are bad (very unlikely) check for AC voltage at the outputs.

It could be your wiring interface. Wen I was doing my install, I realized all the speakers were not coming on until I pushed and held the plug into the interface. As soon as I let go, some speakers would cut out. I replaced the adapter (interface) box with another and worked fine after that.

Vince, if this were the case, wouldn’t he have no sound at all ?

highs run from radio amp. Woofers have a dedicated amp.

if they worked before, then not an issue with the connections, but perhaps an issue with the connection or plug deteriorating over time.

depends who installed it. Go back to the person who did the kenwood. I am guessing they put in the adapter.

While it isn't typical to close a thread until a solution has been found and relayed to all those that were interested or helped by offering things to check, since you are the originator of the thread, you are rightly able to ask for it to be closed.

It would be nice to make a final post stating that the issue has been found and corrected, what the problem and solution was, etc.
