Does the basic radio have rear speaker outputs?

The factory stereo's crossover is the little capacitor on the tweeter.

You can house the cross over under the dash and run wires to your TW and through the door gromit to the woofer, or place the crossover inside the door panel, run the tweeter wire through the door gromit and into your tweeter.

Eitherway works but you need to run wires from the cross over through the door gromit at some point because there's not only the crossover for the tweeter, there are choke coils for the woofer's F0.

GL!

Ok. Does the factory wiring just "Y" off to each speaker or does it have a separate dedicated output cable for the door speaker and the dash speaker? If if it uses a "Y" I should be able to connect the factory door speaker output cable to the crossover input and then the crossover woofer output to the door speaker and the crossover tweeter output to the tweeter and just abandon the factory tweeter cable. This would allow the crossover to be mounted in the door and piggyback the crossover tweeter output cable on the large factory cable harness serving the door and then to the tweeter. Is this the way to go?

They just y off and the tweeter has a little resistor that they use for cutting out frequency.

Someone does not know how to build passive crossovers.

Ok, but just to confirm, I CAN use the factory door speaker cable as the source to feed the crossover. The reason I ask is if factory feed for the door speaker is a full-range audio feed I'm good to go, but if it is only a low frequency source I'd new to find a different source for the crossover.

That's a capacitor, not a resistor.

Correct!

Correct!

capacitors store energy I doubt they would use that for blocking frequencies for a tweeter.

Dude look it up.

Shall you now admit you odviously know jack about audio?

Well come on now, your the bigaudiofanat and you don't know caps are used as highpass passive crossover networks. This is basic crossover theory, your the one making write ups about this stuff. What do expect when you say dumb s#*% like capacitors are used for storing energy, capacitors do a ton more than that bro. Get educated about this stuff before stating your wrong opinions again. Google capacitors maybe and you will see what they are used for outside of car audio.

What are you taking in school anyway?

Never wrote a writeup on a crossover and how it is made man. Get your facts straight. You are completely ruining this section of this forum with your annoying comments.

Computer science and networking in school btw.

As an electronics engineer, I can promise that a low or high pass audio filter can be made with a simple RC circuit. Thats a circuit with a capacitor and resistor.
