ok sounds good. do i need the adapter plates for the speakers and also the tweets do those go on the doors or dash?

I'm not sure if you need adapter plates or not, but the tweeter location is kind of personal preference. I tend to not like tweeters in the doors since it makes me feel like the soundstage is lower than I'm comfortable with. I run my tweeters in the dash (for now), but if I'm not mistaken Ron runs a set of his tweeters in the doors.

I didn't have an opportunity to get around to it with this year's install but in a perfect world I would run them in the A-pillars.

Also: when looking for wiring kits beware of cheap no-name brands on Amazon and Ebay. Some of them are probably fine, but there are some companies out there that do shady things like include the wire insulation in their wire gauge.

ok and thanks for the heads up, ill look out for that.

You will need the plates, and given the fact that tweeter position does have a lot to do with preference, as well as processing abilities, I would suggest trying yours in the dash first.
I do have mine in the doors, and quite low as well, but with full processing capability, was able to overcome those inherent issues to suit my personal tastes. I did, however, add a set to my a pillars, and crossed them at 12.5k to raise my stage to satisfy a few judges ears at shows. (personally I think its more a psychological thing) but they seem to enjoy seeing them up there.
For the casual listener, the dash is typically a great spot, even though it is farther from the woofer than recommended.

ok is there a certain plate i should go with??

oh and also you didnt list speakers for the rear so i figured i would go with same brand. im guessing i will need plated for these aswell seeing as the rears are 3.5 and also if i add the 4" will it fit on the amp with sub and 2 fronts+ the tweeters Amazon.com : CTX 4 - Image Dynamics 4" 2-Way Speakers with Silk Tweeters : Vehicle Speakers : Electronics

I didn't forget....lol. I haven't used rear speakers in a car for 20+ years. Simple fact is, you don't need them. I have never been to a concert, or symphony, where there were speakers behind me. That being said, many are stuck on putting them back there, and that's their choice. I won't hate on it.... My suggestion to you is this.... When installing the head unit and amp, run 2 sets of speaker wire to the back in case you decide to put a set in there, you can run them off head unit power, and go with a direct fit 3.5" speaker. no muss, no fuss.
If you are dead set on having them back there, by all means, put them in right away, you can always control with the fader to on/off.

oh i didnt know that and to be quite honest with you i never knew there were speakers behind me untill i started reading up on it yesterday lmfao!:happydance:

Ron i also want to know i have never done anything with audio in a car so this will be my first time doing it.. do you think the install will be easy or should i just bring the car to an audio shop and have them install it? If its an easy install ill do it myself..

I'm at the shop right now getting my 3-1/2's installed. I prefer not ripping out panels myself and am getting older so it's worth it for me to pay someone to do this. If you have the ability and patience I say go for it. If you don't take it to the shop. The 3-1/2's are needing some modifications for fitment so I'm glad I did.

I would say if your not comfortable tearing down your interior to access everything, and are uncertain about crossover points and the like, let a shop do it for you...

It's not a particularly difficult job but it's certainly not easy. As RonRizz and Tadpole say you have to take a lot of the interior apart and you have to have a lot of patience (things never fit the way they are supposed to). Judging by your comments in this thread, you'll probably be better off letting a pro do the job. If you have the time (it may take a few days for your first install), it would be a good learning experience.

yea im probably better off getting it installed.. a couple days ehhh not good. i daily my z in the spring/summer so it would have to be a one day project..

hey Ron out of curiosity will that amp allow me to fit in those 4" rear speakers.. because im thinking my interior will be stripped down anyways so it would probably be best to just stick them in there instead of having to do that later on down the road..?

I would recommend just running them off of the head units amp, or picking up a small 2 channel, such as the power pack and dedicate it to those rears.
( Personally, I would run them off the head units rear channels )
Another alternative would be to find a decent 5 channel amp. 2 channels fronts, 2 channels rears, 1 for sub.
