need advaned help with wiring
 

hey,this is my first post i have a pretty complicated question, recently something happened to my sub and it gave me an idea, whenever i open and close my door my sub vibrates, this is not supposed to happen obviously but it does, and it actually sounds really cool, the idea it gave me is having my sub go off like it does when i open and close the door but when i accelerate so basially the sub would match the sound of my exaust accelerating. this is a pretty advanced question to ask but i looked online and couldnt find anything so im wondering if anybody here can help me, Thanks

You could setup an Arduino to watch engine RPM. The Arduino could then output a signal to the sub's amp and change pitch and/or volume based on the RPM.
