Wow, that'd be one helluva system! I'd imagine the rubber motor mounts isolate the engine pretty well. Something else to think of would be the current drain; I think you could be short-changing your ignition system if your stereo yanks too much power out of the charging system.

That's not actually the issue. Engine knock occurs at a frequency far out of the range of subwoofers. If subs could cause engines to knock, nobody's car would run when trains went by, or any time a hot-rod with an uncorked exhaust passed for that matter.
