i recently installed a 4-ch and sub amp into my car and i now have a whining noise whenever my car is on. it gets louder when i accelerate. also it only comes out of the front speakers. it is not there when my car is off. my ground is about 8" long and goes to the floor of the trunk and is scratched, shiny metal using my own screws and star washer. power and signal wires are ran on different sides of the car. what can i do to fix my audio. its loud like i like it but i do not like the whine. please help me!!
<p>Henry,</p> <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> <p></p>
