Easiest and cheapest way to highpass stock speakers

What speakers are these? Such as brand and model.

ok im lost care to entertain me im bored

i really dont know the detailed info on it. i just know the basics. but basically inductance changes with the frequency, and it plays a part in the natural frequency response of the driver. if you find this information out, you can match it with the appropriate inductor or resistor to roll of the highs or lows at the freq you want to cross it at.

probably factory chrysler something or other.

inductance affects highs more then lows. so its not normally a large player for the highpass. the T/S effects that occur from the speaker coupling energy to the mass of the cone and suspension do have a large role. crossovers set to frequencies above the main resonance will not work as intended.

basically the impedance of the speaker undergoes an increase of about 5 to 10 times "near" the frequency where the energy of the cone mass and energy of the suspension naturally transfer to each other. at this point, the coil would create a voltage that is in phase with the output of the amp -- which has the effect of limiting additional energy (and thus impedance is higher).

so the filter, which is dependent on impedance, is affected -- if the filter is set high, then the response will decrease a bit until these "resonance" frequencies are reached, then it will increases (up to +0dB). past this hump it will sharply decrease and eventually the slope will return to -6dB/oct.

as for the 3 wire system. it could be a bi or tri way system with either multiple amps, or a crossover located somewhere else.
