This is a frequently asked question, All workable solutions are dangerous and illegal.

BTW, I design car audio. Not too long ago we launched the 10kW amplifier. Brace yourself.

10 kW at 12V makes 833 Ampere. For a 50 Ah hour battery that makes .06 hours, or 3.6 minutes. After that you cannot star anymore. Must be 'music power' so 10 W rms? LOL

You need an EMP generator that focuses about 100 Megawatt electo-magnetic impulse on an offending car. The military has done a lot of work in this area to disrupt communications and even vehicle operation. It would be perfect for killing boom box bass and other thump-thump acoustic pollution one often hears. See if the rocket scientists on this group can assist you in making such a device.

BTW a nuclear bomb gives off an EMP impulse that can probably disrupt bass thumpers. All you have to do is set off a hydrogen bomb near the offending car and the problem is eliminated!

I have an idea. You can do it if the vehicle you are driving is an old style diesel or something. Anything that needs modern electronics may be damaged by this idea.

If you run a DC-DC converter off the battery, you can charge up a bank of capacitors to about 1000V. In the area of the back seat of a car, you could fit enough energy to make a darn good EMP pulse.

The feed horn could be built into the front of the car. You would just need to get close behind the offending car a hot the button.

er.

10kW may not be nearly enough. Some fast acting values and a compressed air tank can do a lot more than a mere 10kW.

Your math didn't include putting about 10 extra car batteries in just to run the audio. It wouldn't be super hard to get an alternator big enough under the hood of some cars. On a hybrid you already have an electrical machine bigger than that.

Yes, OK, one could also set of nukes at precisely times intervals to enhance the bass, look up 'project orion' and similar ideas:

That was considered. Actually, the hydraulic actuator makes perfect sense for the woofers at the power levels of ~tens of kW.

Vladimir Vassilevsky DSP and Mixed Signal Design Consultant

Ok, with the ten extra batteries you're up to 40 minutes. ;-)

Modulate the control rods; Class-N. Perhaps a Mr. Fusion and a banana peel?

10 Kw at the 7.5 hz "Stomach Resonance" frequency must make every puke within what ? 50 meters?

The amp delivers 10kW RMS undistorted sine wave into the 2 Ohm active load and sustains the operation indefinitely. It is powered from 12V and drains about 800...900A. You can feel the power leads pushing away from each other in time with the beats in the music.

Yes. There is a whole science of how to add 2-3 custom alternators and a bunch of batteries.

Vladimir Vassilevsky DSP and Mixed Signal Design Consultant

Huh? Do you seriously think that it is possible to hurt the kilowatt level class D amplifier by a reasonable EMP?

Too many side effects.

Why hydrogen bomb? A baseball bat is lot cheaper and cleaner.

Vladimir Vassilevsky DSP and Mixed Signal Design Consultant

You can get electrohydraulic servo valves that work at thousands of psi with bandwidths in the hundreds of Hz. You could use the same hydraulic pumps and accumulators for the bass drives and for the pistons that make the car jump up and down.

Noble work indeed.

Set it off in the trunk, just to make sure.

BTW, Ken, what do you think would be the voltage to accomplish the max. density of energy using the standard capacitors?

Vladimir Vassilevsky DSP and Mixed Signal Design Consultant

It depends a lot on what you consider "standard". The goal here would be Watts not Joules.

With film capacitors, 2 Joules per cubic CM seems to be the limit for voltages from about 50 to over 1000. As the voltages goes up the capacitor grows so that the energy per unit volume stays nearly constant.

Down at low voltages, things like supercaps can store a lot of energy but they can't discharge quickly.

LOL. Here's the thing, since most cars these days are highly dependent upon CPU's you can be sure that not only will you hear the Thumpa-Thumpa stop, but the car will stop too.

It would also be a very expensive repair.
