Tweeter Wire Harness
 

Hey everyone, I'm new to car audio, so please bear with me. I'd like to replace the tweeters in my FR-S without having to cut in to any wires or anything. Since there are 4 wires that plug right into the stock tweeter with a harness, does anyone know of a harness/adapter that that could plug into instead, giving me bare wires to run to my replacement tweeters? Also, I just had time to take a quick glance, but why are there 4 wires going to the tweeter instead of 2? Is something running to the other speakers mounted in the dash as well?

there should be adapters available, just not sure where from. I bought some for my tC speakers but that was years ago.

I'm interested in this too. Anyone know of one?

anyone find a harness for this? im looking for one.

Carbon Car Systems
 

Carbon Car Systems used to carry some great adapters and harnesses. The bad thing is they are located overseas "from the US anyway" and their videos are dated so not certain what they still offer?

I have yet to pull things apart and map out the OEM wiring on my own car as of yet ... but .... to my understanding a full range range speaker level signal comes from the OEM head unit and run up to then back out of the dash speakers. That is why you see 4 wires at that location. The dash speakers use simple capacitors to limit frequencies to upper mid and highs getting to the driver / drivers at that location. The wires leaving the dash speakers then go back to the OEM amp located in the back of the vehicle. This is still a full range speaker level signal which the amp picks up only the lower frequencies from and "amplifies" sending to the door speakers "woofers" I think some models do not include the OEM amp so the full range speaker level signal comes from the dash speakers and directly to that door speaker.

If your simply replacing the tweeters up in the dash - be certain they also employ an attached capacitor to limit only higher frequencies get to the driver. Some tweeters are designed to be fed from separate crossover which performs this same function. Full range speaker level signal getting to the driver of a small tweeter will result in a blown tweeter very quickly.

There are a good number of people who know the audio wiring inside and out so if needed I hope one of them will chime in and correct me if I am incorrect.
