It never really did that before, can anyone tell me what that means and how I can fix that? If I undo my seat belt, sometimes that breaks it but it comes right back, or if I lower or raise my window.... It's the craziest thing, but I hate hearing it when I accelerate thinking I got a supercharger or something. It's really annoying.

For me, I've listened to Pros and listened to backyard installers, both will claim to be right, but I just use their knowledge only as opinions and use and make my own judgement. I've been a good backyard installer and don't even listen to the ones who claim to be pros. In my experience people will claim to be pros, certified, etc. but the best mechanics and installers are usually those without certifications. For example ASE mechanics claim to be the right or better but the best i've seen are NOT ASE certified. I prefer people with experience not necessarily certified. I'm not saying anything bad about rave2n, I'm sure he has his concepts right. but Whatever pros say, who cares, we don't have the time or money sometimes and if you wanna be truly safe seperate the wires on either sides. Just get a good solid ground thats it. Who cares about good wires you can take care of it and not worry or spend more money by just seperating it and also getting a good amp ground. Lets not make it more complicated its just fundamental sounds not bass or decibel competitions.
