Keeping HU and changing all speakers
I have read many posts over the last 2 weeks to educate myself with the stereo shops. I knew about close to zero on this topic when I started and now figure I know about 100 fold more!

Still not enough to do my own install Some of you guys are amazing!!
I went to 5 different ones and each time got more educated with what I wanted to achieve. I even showed picture posts of the doors and trunk area that were posted here on the forum
This is what I have ordered
JL Audio Stealth Box 10" sub woof -This was made for the left rear corner of the vett
Focal 3 way in the doors consisting of:
Focal 100KP for mid
Focal 165 K2p &TN52 tweet
I learned that the center stage is the most important from you guys
JL Cleansweep- allows me to keep my OEM HU & Factory Nav
Dynamat
Kenwood rears to fill sound
Audison LRx 5.600 5 channel 600 watt amp
Box/compartment made directly behind seats in rear trunk area that will have the option to remove lid and show or go stealth with carpeted lid. guess no loyd mats for me in the back.
I will post pics as they do the work. 2- 3 day job
They have to remove the middle console
and also install 2 volume controls where should these go?
The shop is a busy high end install place with guys that are real pros. Luckily they were also just down the street so I can pop in anytime and see how its going.
They spend as much time as necessary adjusting the sound to my likeing
EDIT..IS THAT A Z06 AND ARE YOU IN SANTA MONICA? hey...uhm.. you should swing buy and take me for a ride in the z06!
Unless you are big in to DVD's or 5.1 stereo surround I honestly think you will like just the focals better.What crossover are you going to run? Passive Focal's only? Hopefully they are a biampable 3 way passive crossover? If it is not you are going to need some sort of external active crossover. With 5 channels of amplification you have 2 possible scenarios:
Channel 1/2 to Focal passive crossover powering the 100kp/tn52
The high pass point will be handled by the amp crossover rest by Focal.
Channel 3/4 to Focal passive crossover powering the 165k2p
The High pass point will be handled by the amp crossover rest by Focal
Channel 5 to the sub crossover handled by the amp
This scenario really only works if the crossover is biampable.
Clean sweep rca's to external crossover.
RCA 1 to channel 1/2. Channel 1/2 to passive crossover for mid/tweet.
Crossover high pass point handled by external. Rest by passive Focal.
RCA 2 to channel 3/4. 165k2p directly to amp channel 3/4.
Both high pass and low pass handled by external crossover.
RCA 3 to channel 5. Can choose either amp or external for crossover.
Focal passive crossover's generally have 3 filters. Some are on a 12db slope (ok) some are on an 18db slope (better). Crossover points are generally:
Midbass (165k2p) No high pass point / 300hz low pass point
Mid (100kp) 300hz high pass point / 3.5 to 3.8k hz low pass point
Tweet (tn52) 3.5 to 3.8k high pass point
Hope this helps before everything gets situated and layed out. I can promise you that you will want to control what speakers are playing what frequency range as best as you can
EDIT: Also realized I ran down the options without the Kenwood rears included. Definitely don't want those speakers trying to play too low (probably somewhere similar to where the 100kp's will be possibly lower IE 150hz or so) Really running out of options without sending the amp too low an ohm load to get those included somewhere and be able to manage them at all. If I were your installer I would be trying to talk you out of them
PM me if you have questions or for a number to call:

Now I know who to call when I start getting into these kinds of messes in the future.

I remember one of them saying the same thing as you that front speakers are everything and skip the back, and another saying oh you need something to fill the rear. So I said then just put something cheap back there to fill
I think I agree with you or will at least try the hookup with out first. I had a price point I was trying to stick with.

I am thinking of ***** where the ash tray goes


Would like to hear your system too.

With rear speakers you generally degregade your sound quality up front because they are lesser quality speakers and are poorly aimed . .and as I have said many times ever been to concert with "rear fill" speakers? Or ever turned and faced away from the stage for that cool "rear fill" effect? I sorta thought not
G'luck on the install should sound great. Question how/where/how much are you getting the 100kp for?

i just ordered a set from fred beans and they are pretty nice (expensive for what they are though)
Oh... and you are not going to be allowed to listen to the system until i dynamat..i'm ashamed i havent done it yet. I'll pm you with my # though. I'm planning on sound deadening in 2 weeks. and let the new install start!
oh btw for any of you trying to piece together my install there was kind of another hint in this reply


Yep ZO6 from Santa Monica,and in Marina Del Rey/ Venice several times a month. And your in Venice , pretty close. PM your # and next time I am in the area I'll give ya a buzz and see if your up for a spin

Rockford is coming out with a unit that does all the clean sweep functions and includes full EQ for front, rear, center and sub channels. Full crossover, selectable 12/24db octave crossover for each speaker, and adjustable output levels as well as time alignment. All done through bluetooth on a Palm Pilot. There is a level control **** that can be selected as a ssub level output or master volume. It also acts as a auxiliary output volume control if you use satelite radio, Ipod or whatever. There is also a scaled down version for those who don't want to be overwhelmed with all those features that have basic eq functions for 5 channels.
I believe they will be shipping within the next month, and I am currently running a test model in my car and the adjustability is great.
Here is a link about it if anyone wants to ressearch the specs.

Good luck with the install, I'm sure whatever happens it will be great regardless.
Oh, and as I learned from everyone here, we love pics!!!!

I have another thread with (pics)
As far as the clean sweep it does the job for me , I could of added Audio Control but not that interested in changing and tuning all the time for the variety of music I listen to
ie: today I started off with GreenDay, then Celine Dion and threw in some rap forthe bass along with LA FM radio 93.1,95.5 98.7,106.7 and then XM Sattelite about 6 presets so I am all over the board.
I will say this, The system is so much (repeat with emphasis) so much more c l e a r .
