I just installed new Polk components in the front and rear of my 01 grand cherokee. The rear speakers are working great but the front are not getting much volume and one of the tweeters has a hiss to it. I have tried it with a known good tweeter and the issue is still there. I checked all connections and even re ran the wire to the amp so that it is not near anything that may be interfering and I still get the hiss. I have not tried a new crossover yet but that is my next step. Any ideas as to why I am getting the hiss and why both front speakers are not getting much volume? im sure that it could be a number of things but any suggestions would help.
