So I've just recently put my subs back in my truck. Before this I had just my component set and an amp to power them and my speakers worked fine. Since I've installed my subs again I've been having a problem with my speaker volume getting scratchy as it slowly starts to die away until there is no volume being produced from my door speakers at all, yet the subs will still hit. They are on two separate amps, one for the component set and one for the subs.. Anybody have any suggestions as to what might be wrong here?
