yeah i dont wanna go lower than 10" myself

As mentioned before I to do not recommend rear speakers in a sports car. In my altima I am not going to be running any rears and my system will be over 7k

I've been having good luck with mine also ! atm its putting to much power to the stock speakers. I have to be careful. I did not have the Bose system.

So what's the difference between the Kenwood DD... And the 9990 ?

Agreed unless you listen to DTS Cds and have a system capable of decyphering the surround data, rears are not nearly as important as the fronts. That said, having fill is not per se a bad thing given psycho-acoustics response to not being in the ideal sweet spot (center between two speakers). Keep the stock rears. If you don't like it, you can always turn it off.

He would not be able to run the rears off a new head unit unless he is running it through the stock bose amp and speakers. There 2 ohms I think and would blow a head units amp.

Also even with you and I agreeing on no rears some people just find that they miss it and want rears.

To me makes completely sense to not touch the rear speakers and that's what I'm going to do. Now leaves me with more money to spend on front speakers and tweets. So I'd spend up to $400 on the door speakers and tweets.

You should be able to get a good set of components for a $400 budget. In addition to the ones already suggested by big, you might also check out the HAT Imagines or Massive Audio CK6V's. I've read good things about those over on DIYMA.

How much are you looking to spend for an amp? The PPI P900.4 looks like a good small-footprint budget amp with a lot of power or you could go with the tried and true Alpine PDX-5.

X2 on that pdx-5. 400 is a great budget for some good components just keep in mind you are going to want to go in this order.

1. Head unit
2. Amp and speakers at the same time

Here are a few recommendations. Keep in mind all these will have clear sound and all will sound a 10 times better than the bose system.

Focal Performance PS 165 6-3/4" component speaker system at Crutchfield.com

WoofersEtc.com - ES-620X484 - CDT Audio 6.5" Component Speaker System

WoofersEtc.com - H600S - Diamond Audio 6.5" HEX Series Component System w/ Silk dome Tweeters

WoofersEtc.com - CXS62 V2 - Image Dynamics 6.5" 2 Ohm Component System




Keep in mind a silk tweeter will usually give you a smoother tone where as a aluminum tweeter will be more bright.

I would recomment Hertz Hi Energy HSK165 front.
Unless you want to upgrade to a 3 way set up.
I also would recommend against rear speakers. No need specialy with The Hertz line. Get a Hertz HDP4 run it in 3 channel mode. Of course you will need to upgrade the sub.

Lots of good advice for me too, I upgraded my head unit and sub last year and only put in some basic amps & speakers, now I am looking to upgrade to some quality stuff.

Just one question though is installing the tweeter in the back/oem position difficult, it seems it has a non standard mounting? Or should I just have a coaxial tweeter and leave the oem one disconnected.

The rear speakers are not tweeters just really small coaxial speakers. I would not even worry about them.

this is one of the best ive heard Alpine pro s but maybe cause iam crazy about the ring radiator tweeter . i have polk lsi 9s in my house again the same tweeter i think the tweeter makes up most of the speaker . lots beat these bang for the buck though:)

i was not going to put the rear speakers in my 350 and they are a pain but if your goin for great sound quality i think its worth it i cut my back speakers off and can really tell the diff i know the soud stage is in the front though

Of course its all subjective, and some people just like rear fill, but I try to explain it to my customers in laymens terms.......
What was the last concert you were at that had speakers BEHIND you?
do your front stage proper, and you forget all about the rears.http://www.woofersetc.com/p-9612-hsk...nt-system.aspx
