just ran out to the freezing cold to take some pics for you guys... let me upload them really quick

Since the Bose didn't fit, here was my creative solution to getting some Infinity Tweeters in the rear deck.

I think it looks super clean, what do you guys think?










The beauty is that unless you're looking for them, you don't see them. The headrest does a perfect job of concealing them.

that is very clean too bad you didnt pait them black, it would be very stealth then, but looks great i still cant wait to hear it!

I thought a lot about painting them black but I like the way they turned out so I wanted people to be able to see them if I pointed them out.
With the limo tint on the back window, you can only see them if you're actually looking for them.

that does look very clean

EDIT: I installed my bass blockers, the tweeters sound alot cleaner, bass doesn't distorte them none at all

Tweeter isn't a bad place, obviously you didn't go to the one in Dedham where they are familiar with my car.....

I just did what kwolfman did on the small door speakers except that I used Infinity Kappa 10.7t tweeters.

I experimented with various crossover connections:

(1) no crossovers, just a straight feed to the tweeters

(2) the crossovers that come with the Infinity tweeters

(3) Bose crossovers that come soldered to the Bose speakers.

I settled on the Bose crossovers. I just desoldered them from the Bose speakers and put them between the feed and the tweeters.

The result isn't perfect: there are times when the sibilant level is a little too strong at the level of high end gain I like. But the fix is cheap (about $80 for the pair with shipping from Discount Jungle), relatively easy to do, and results in a much cleaner, tighter sound all around. Also, I personally had found the Bose system very tiring to listen to at moderate to high volume, especially with some voices. The new sound is much smoother and easier on the ears.

I used the "starfish" mounts that comes with the speakers and mounted the tweeters where the Bose speakers had been (behind the grill) so the car looks no different. There are two levels of mounting holes on the starfish. I used one low level hole, screwing it directly to the door panel. A high level mount lined up exactly over the other mounting hole so I used spacers there. The starfish mounts are designed to snap off easily so that you can remove the mounts that aren't needed or that get in the way.

One word of advice: be very careful when handling the wires to the Kappa speakers. They are only soldered on to small terminal on the back of the tweeters. Three of the wires broke off while I was fooling around with the mounts and I had to resolder them.

Thanks to Spin9 for advice on installation.

what would be the best bass blocker or filter to use if i completely replace the bose mid-highs?
i'm installing the boss TW-15's. I'd like to kill some of the overpowering mids in the stock system. the center channel should provide enough mids which is why i plan on getting rid of the mids in the doors. the tweeters should really fill out the system.
any opinions on how to filter them properly???

Here are some pics...

When you add some highs, your mids will probably not be overpowering. It just seems like it now because there are no highs.

Keef

same thing I did I think, but I put the tweeters directly in the center instead of on the side...

I replaced the bose tweeters with focal and used the bose cap as a crossover, I suspect the slope is tpp high for the focal since it is rated down to 2000Hz. Any idea how much cap should take to go to 4000-5000? My sound is vastly improved as it is.

Spin9k

I like how you guys are developing some good stealth solutions to adding tweets!
The 2 way mid-tweet looks sweet - I might just have to do an upgrade on mine
with these ideas in mind - Keep up the good work...

Update on my Focals. I checked the specs and these are 6 ohms. The Bose cap is 22uf which would give you a xover of about 2000 or less. So I replaced the cap with a 10uf so as to get around 2500. The Focals are rated down to 2k. Wow! the sound is incredibly better, even the bass from the doors sound better, amazing for just 99 cents. With these Focals you do not need to keep your stock "mid" Bose, they do it all. I just drilled out the sail panel and epoxied the Focals for a flush mount that looks stock except for the Focal logo.

i received a set of boss tw20's rather than tw15's. i guess the vendor ran out & threw these in for me. anyways, they have a higher range starting at 5k. so, i'm going to wire them in & keep the stock bose 2" behind them just like the pics posted here. i'll keep you guys posted!

Hey Razz, don't know how I missed your post, sorry.
I got all my Infinity speakers from www.ikesound.com

question for slick8...
how did you manage to glue the little tweeter in there? i can't think of a way to glue it on without having it's rubber surround touch the surface of the bose sail grille. i need a way of securing it in there...

Keef

ya, I have a pretty complicated question... Doesn't adding on a seperate tweeter change the ohm'edge??


I replaced this little set up with 2 Boston Acoustics SL60's and the crossovers that come with them... The sound is ALOT better... Just so clean... And since the SL60's run at 4 ohms, I know that the 9 inch Bose speaker will run at 4 ohms...

But either way, doesn't adding that little tweeter change the ohm's too 2?

Slick8

I used epoxy putty, it's like playdoh until it sets in 5 minutes. I used PC-7 Epoxy Putty that I got from Pepboys. The epoxy putty is available at any auto parts store for $3 to $4. It's also called plumbers epoxy putty, probaby available at homedepot or lowes.

After kneading the putty, I rolled it up into a little ball and then just smushed it to stick after I positioned the tweeter. It's the grey stuff in the pic below. Careful to leave some room to route the wires where the putty should attach.



This tweeter is a poly dome with a protective faceplate and does not have a rubber surround. The protective faceplate presses again the back of the bose sail grill and does not impede motion of the tweeter diaphram.

have u noticed any issues w/ your amp and the impendence change when running these in parallel? i'm assuming the amp is just fine cuz this mod was performed a while ago already...

Slick8

There shouldn't be any issues with the stock amp and the impedance change when running the tweeters in parallel. Tweeters are efficient and require significantly less power at higher frequency load.

Thinking I can remove the stock "tweeters" entirely and flush mount my Adire Audio Koda tweets in there. I do believe they're 2" in diameter. Think they'll slide right in.... any thoughts?

Spin9k

here you go...a little dremmel tool and I got these really deep 2" Logitechs(compared to the Bose units) in there.

Thought I would add my latest mod here instead of starting a new thread.

Since I mounted my Eclipse 3-ways in the door, I needed to bring the soundstage up a little. After trying a couple different brands, I got a hold of some Rockford Fosgate T1T Inverted Dome Aluminum Tweeters. They blend perfectly w/ my components & they fit perfectly behind the sail pod w/ no modifications. They actually face back a little more than stock.

Right now I have an Eclipse EA4000 pushing the front & rear components w/ the front channel of the stock amp pushing the tweets. Everything (including the stock amp) is being fed through a JL CleanSweep.

Once I bump my doors up to 150w, I will probably have to bump the tweeters too, but for now it sounds great.

But wouldn't the impedance change mean you need to adjust all the calculations for the capacitors? Effectively doubling them to maintain the proper crossover point? (i.e. 22udf must be changed to 44ufd to maintain 1800hz crossover on whats now a 2ohm load).

I am working on adding tweeters and wrestling with determining the proper capacitor I need to protect the new tweeters. Also just the act of adding a 2nd tweeter in parallel would lower the impedance from 4ohm to 2ohm, thereby changing the crossover point on the stock boss tweeter. So don't we need to change the stock capacitor to avoid tweeter damage?
