Hello!

I installed a bazooka type subwoofer. The tube was in my previous car and worked fine. It is installed the same way in my smart but there is a problem.

The sound system works fine until I shut everything off. When I restart the car or turn the radio on again, there is no sound at all from the speakers or the sub. I have reviewed all connections three times and all is good. (left, right, positive, negative etc...) If I unplug the wires at the sub, (sound feed from speakers) sound comes back and I can replug the wires to the sub. Everything works t'ill I shut the radio off again. The easy fix would be adding a switch on the speaker line but I wonder if i'm missing something.

Help anyone? Links, suggestions?

Thanks.

Thanks for the help, problem solved.
OK - how did you solve it??????
Are you using the factory head unit? Where are you getting the input for the sub? It may be the head unit is seeing to much speaker resistance.
