## Questions & Answers

**Q: What amp what I want to wire up to 2 of these**
A: these tweeters are 4 ohms; the nominal power is  200W (constructor; measured with white noise meaning less with fixed frequency) . If you connect 2 in series (total of 4 for stereo) you should also connect the 2 caps in series. The max power for amplifier is then 400W @ 8 ohm.  in series you have a safety for power transients (poks!!!) I recommend to do this wiring. 
Another possibility is connect them in // then you have a power of 400 W @ 2 ohm. In this case each should have its own cap in series. For cars this can be better as voltage at output can be lower and more power for amp at 2 ohm. If the amplifier is not designed (and cooled) for 2 ohm you will destroy the amplifier or have overheating) then connect them in series

**Q: Are these ones , the ones showed in the picture of pioneer.com, because on that picture the middle of the component is red, and on this one it is gray**
A: The ones I received had the red middle

**Q: can they be install in the door of my car**
A: What kind of car you I have toyota lasso I install 3" in my door.

**Q: Do they 8ohm tweeter 4inch ????**
A: They are 3 inch and four ohm
