<p>A few things to check are going to be the gain settings on the amp. Remember the gain in not a volume control it is a sensitivity control. Matching the output voltage of you deck to your amplifier. With that being said if it is too high it will pick up a wine or hiss. Another thing to check is your RCAs. Switch the front channel RCAs to the back channel do you still get your whine? If an RCA is pinched or damaged/bad it can cause interference like that as well.</p>
