I have a 10 inch Kicker Comp R with a 300watt amp connected to it. It’s set up in a 2013 Honda Accord LX and when I turn my car on it bums very loud, when I press on my gas pedal it stops the returns seconds later. When I open a car door it stops and comes back when it closes again. The sound sound just like a test tone you would play off of YouTube and is very loud, why is this happening? The ground is good, my wiring from the amp to the sub is good I checked. Is it my head unit or interference?! Please help
