Hello Jeff. I have never heard of three way components. All the components at Crutchfield are 2 way (this is where i usually reference equipment i see on the web). How do 3ways compare to the 2 ways, and is there a big difference? I would think there would be a fuller range of sound. If you don't mind me asking you can you advise on some other 3 way Components, and how much and where the hertz speakers were purchased? After doing some looking around I found this set 2009 DLS UP36 3-Way 6.5' Component System which consists of a 6.5" and a 2.5" and a 1.1" tweeter.

I've never heard of this brand nor Hertz, but they look like high quality speakers.

Unfortunately I already purchased the JL C5-650 components before i saw this thread. How do you think these 2 ways would sound in comparison?

Thanks

David the Hertz HSK163.3 3 way's sound amazing! 75% of your sound stage will rise from the dash and not from the doors like in a conventional 2 way set with high x-over points. The only way I could see a 2 way set coming close to this sound would be a large soft dome tweeter with x-over point around 1.8-2.8k The other benefit to this system is that Kenwood DNX8120 has separate front 13 bands and rear 13 band eq's with Time correction for speaker placement. Now step back and look at the system that I installed for SRR2449 and I'm gonna clue you in on a little secret. The rear speakers in this car are worthless (IMO) disconnect them. Using a 3 ch amp like the audison LRX3.1k allowed to to take the front L rca and connect it to the Left front input of the amp. Then take the right rear and run it into the right front input of the amp. This gives you independent left and right eq for the best possible SQ tuning!

Now this I am very interested in! Being able to keep the spare AND have a stealth sub setup so I don't loose trunk space. Please keep us informed when you have tackled this project.

Assuming all that you've done here, same equipment, etc...

As far as adding a 6W3 - would it be worth doing that if you *also* have the bigger woofer in the spare location? A sort of more-detailed mid-base woofer?

Thanks for taking time to answer questions!

Hello Jeff. Thanks alot for this information but I am kinda lost on a few points here. You mention that the kenwood dnx8120 has separate front and rear bands;however, you are not using the rear ones correct? Also you mentioned that it has time correction. If this is the case do you feel that we could add a set of rear speakers and use this time correction?

The part about the 3ch amp, I do not really understand this. Are you using the third channel? Can you ellaborate more about the inputs going into the amp. what happens to to the right front input coming from the head unit? and the left rear input from the head unit?

Also, can you let me know where and for how much i could get a set of the Hertz 3 ways.

I try not to quote prices over the internet because custom shops charge differently due and prices on equipment and customer relationships. But I can say that SRR2449 got a great deal.

As far as having 2 sub woofer systems I seriously doubt that you would want both. The 6w3 set-up has worked with great results in many Porsche 911 installs that we have performed. Now there may be enough room to install a shallow 10" sub in the spare tire itself but it may not give the best desired low bass effects.

Thanks Jeff. I was really just trying to get a ball park figure to see if it was in my price range. I didn't really want to be spending more than 400 for a set of component speakers, but I am pretty sure they would run more than this. I called up one shop and they gave me a price of 600. I am not sure if this is high or what not but i'm thinking for now I'll wait on these though they look really nice in you install. I was wondering for the pillar. Did you actually drill out all the little holes and then wrap it with the grill cloth? Also the black stuff holding the tweeters in place, is this like black hot glue? I really appreciate all your input and help. I still do not quite understand what you were trying to say about the three channel amp though. Now that I've given it some thought, I am assuming that the right front signal and left rear signal are not being used? I understand if you rather not go into detail about that.

Midbass 450hz-40hz
Subs 50hz

Kenwood DNX8120 has EQ and time correction in it. The car images and stages like crazy!

I do not understand this explanation, can you expand please.

What do you mean that the tweets are 1" above the mids???? I am a little lost....sorry.

david712370 04-25-2009 10:50 PM

the mids are in the dash.... and the tweeters are int he pillar which are about 1" above the dash.

This is correct!

Could the factory tweeter covers have been left without the added grillcloth and still look stock, no modifications needed to the covers? And could the pillers have been left stock with no cloth wrap as well, just a small grill cover for the tweeter? Thanks.
