I just installed a new amp (USAmps tu-4360 hybrid tube hi-fi) in my car. One of the four speakers is getting a very weak, fuzzy signal that makes the speaker sound blown. When I hook it up to other channels, it sounds perfect. The speaker is a JL XR evo series 6.5" 650CSi comp. Is the channel on the amp fried or is there something else it could be? If there is anyone out there that knows, I would appreciate some info.
Another thing, how important is a line driver for RCA cables?
