Type R components
 

I got a stereo installed a while back in my 02 Civic LX, Alpine Type R component speakers in the doors running on channel 1/2, and I have been having problems since day 1 with the speakers cutting out…not completely so there is no sound, but it sounds like the amp is not giving the power any more and splitting the sound between the woofer and tweeter. I have a Visonik sub running on channels 3/4 which is always fine. Any ideas what's wrong?
