Tweeters in back seats?

[SkwurlyFab 10+ year member]

Is it just me or do most people only run tweeters up front in the pillars or the highest part of the door usually?

Is there a reason why people don't run tweeters in the rear a lot?

If I were to put tweeters in the back of my car, what would be the best place to mount them? In front of the rear passengers on the door somewhere or somewhere behind them at head hieght around the trunk? o and this would be in a 4runner.

If you are after the best possible sound quality, you aren't going to want tweeters in the back. They will smear the image from the front speakers and will ruin the overall frequency response of the system.

Many people don't run rear speakers at all, in fact, myself included. If you have good speakers up front, rear speakers aren't needed. Even if you routinely have rear seat passengers, you'll not likely miss rear speakers, they'll be able to hear the front ones. Adding rear speakers without any delay processing creates a situation where the sound from the front and rear speakers arrive at your ears at different times. The result is phase differences between the sound from the front and rear speakers. This phase differential will cause destructive interference at some frequencies and constructive interference at others. The end result is a very ragged response curve.

If you feel that you must have rear speakers, run minimal power to them and use delay processing on the front speakers to get the arrival times as close to the same as possible. I still think that your best bet is to forget about rears altogether and use the money that you would have spent on rear speakers and amplification for them towards better front speakers and a more powerful amp for them.

time delay. thank god for zapco digital sound processing

I'm definitly not all about SQ, but I don't want it to sound like shit. what would be a good place to put the tweeters in the rear? The only reason I want to is for things like tailgate parties and the dezert. the louder the better and it seems like 4 tweeters would be better then 2 if I'm not going for perfect imaging right? so what's a good place to put em so they don't drown out the rear and front mids?

i've got mine right on the doors, wanted to put em on the rear door pillar but i don't want a permanent hole.

If you want them to listen to outside the car, they are not neccessary. I have my mids mounted in the doors with tweeters inside on the a-pillars, and when the front doors are open and the volume is where I normally listen to it, you can hear it crystal clear about 80 yards behind the truck.

80 yards = 240 feet

maybe in a perfectly silent city.

I used to do the same thing in my old truck. One tweet in each front door and with the doors open, there was plenty of volume for tailgating, or waking up the whole quad during basic. Only had a 225 HCCA Orion running in stereo to the front, too.

Or out here in the country lol, not everyone lives in Cali. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif No, I am not exaggerating, you can hear it crystal clear to about 250 feet. It's not loud by most people's standards, but you can here it well enough to listen to if you are working, etc.
