I mean I know rattling door panels off isn't good, but is there any other effects, such as perhaps getting into the cylinders and confusing the computer/possibly damaging the engine or other parts of the car?

Any equivalent, such as going over the train tracks or bumps?

I know it can't be good...

It'll loosen gaskets around windows and bolts all over the car with enough pressure, but I'm not sure about the ECU and other components

Any idea how much pressure you need?

Is it only with windows closed or up most of the way?

never heard of anyone having enough bass to destroy electronics before. I have seen spoilers knocked off. license plates fall off. rear view mirrors. doors.........the list goes on. but mostly things that are screwed or bolted on getting loosened up.

even then, you have to have some serious SPL to do that kinda stuff.

Cars vibrate all the time so most electronics are built for that from OEM, built to last. You can see with cheap amps sometimes they break if mounted on a box for example, from vibration and impact. Sound waves and the power used should not bother electronics in the car, unless you use all the power so they don't have enough. If you read up on SPL stuff you will find what breaks in cars from it, mostly mechanical things that rattle loose. SPL cars have eventually broken spot welds and such, but you are talking serious high output not a typical daily driver than goes kind of loud.

I wonder if the ecu could ever mistake bass for engine knock and pull timing. That would be kind of funny. Every time your bass hits the power drops off, haha.

And it also effects the air pressure right?

knock sensors are in the head, i doubt they even feel the bass from your system.

Impossible.

Knock sensors are piezo electric, and are listening for a ringing in the substrate of a very specific frequency range. 5000-15000hz is typical.

Haven' you guys figured out the OP is trolling yet?

I've heard of some Subaru people that had issues I recall with heat shields rattling and causing knock sensors to pull timing. However, that is true that the frequency would likely be very different than sub bass.

If in doubt remove your sub.....:rolleyes:

Bass taxes your electrical system (if not done right), which is why you may see some people's lights dimming every time the bass hits. I had a friend who had a Brahma 10 in the trunk of his Protege, and that thing hit so hard. His paint was actually starting to crack from his trunk flexing in and out. I am sure it is bad for creating new rattles in the car from panels vibrating so much, but that is what sound deadening is for!

To some degree it might but it all depends on what you're running. For the most part I wouldn't even bother worrying about it.

If you use 12 tweeters it will counter the effects of the low frequencies.

Come on man! Get real! It would take way more than 12 tweeters to equal the sd of even 1 10" subwoofer. Do the math!

Unless they were high Xmax tweeters.... Maybe your on to something?

I always thought the opposite, that bass actually helps your car last longer...

The last thing bass is going to hurt is the powertrain. Electronics over time, maybe. The harmonics that go on within the block, crank, and especially valvetrain are crazy and no amount of bass will be able to match 1/10th of what the drivetrain sees on a daily basis. No chance in hell of it setting off a knock sensor unless it causes a foreign object to vibrate against the block or heads. In the old days I could trigger the knock sensor on the GN just by banging on the headers with a wrench. Today the ECU and filters are much more frequency specific.
