Speaker crossover location?

[V1nny]

Is there a frequency crossover anywhere in the door on non-bose cars?

not from what i could tell, there were no resistors or coils or anything different going to the small speakers near the door handles just looked like additional wires from "larger" speakers on the bottom of the door.

Thank you for confirming. It has to be somewhere else, if not in the door card

Typically just a cap that's right on the tweeter. It won't have a full crossover, just the cap for a 1st order filter on the tweeter.

You are exactly correct. It not literally right on the tweeter, but soldered into wire about an inch away, very small and covered with shrink tube. Replaced tweeters, crossed them the at 6 KHZ, with proper second order crossover, already had some high efficiency 6 inch midbass that are more like midrange, so crossed them hi-pass at 80HZ, and added second 8 inch sub to cover 30 to 80 HZ range. Sprayed some sound deadening, and it sounds so good, I am sometimes forget where I was diving :)

hey sorry v1nny there was nothing on mine, just straight wire from the "mids" to the little tweeters, and it looked factory, doubt anyone had been in there before me.

no worry, these tiny capacitors are easy to overlook

Glad you found it. Good idea on the crossovers, it's nice if you can do them in the amp.. I had some Polk DB series and thought they were low on bass. Recently I popped them into 6.5" bookshelf speakers and was surprised they're like -10dB down even at 60Hz compared to some cheapo woofers. Definitely not reusing those in the car!

All car audio is tough due to passenger location, driver placement and shape of the interior.. 6kHz is nice for the tweeter but that's pretty high for the location of the mid-bass driver. Where did you put the 8" driver? I'm looking at doing the interior in my ratty Allroad and doing something with a sub while I'm at it.

I tried Polk MM series. They are not bad speakers. I am sure there are cars where they sound good. Problem with C5 Audi, speakers are attached to flimsy door card, so only way to reduce distortion is to let door speaker to play above 80Hz, not the deep bass.
I have efficient neodymium mid-bass and aluminum tweeter that each have hi-pass second order crossover at 80Hz and 6KHz respectively.
If anyone interested, I could share my entire setup
