I have the following equipment.




As you can see there are some tweeters and a pair of crossovers. From the images you will see there are 3 tweeter mounting options
(i) flush with a panel (directional) (top pic)
(ii) raised from a panel but parallel to it (bottom pic)
(ii) raised from a panel and angled (top pic)

So, I don't know what to do with these and am hoping for some suggestions. I've seen the how to on putting these in the dash mounts and that's an option. Would this be the best options or would I be best to keep the ones in the dash and mount these somewhere else.

I guess that unless I want to keep the ones in the dash and use these somewhere else then I don't need the crossovers?

If I do want to put these somewhere other than the stock dash position suggestions welcome on where to put the crossover.

Steve

Identical to what I've got. I cut the old tweeters out of the grilles and glued the new ones into place. The crossovers then fitted into either end panel. Simples.

Why do you need the crossovers if you are going for a direct replacement Stan?

Steve

Er, good question, not my part of ship so to speak but I believe the coupé didn't have a crossover as standard, and I was fitting matching speakers in the doors so it seemed wasteful not to use them. I've never found crossovers in the coupé, maybe I haven't looked hard enough!

Logically I thought the crossover was for when you want to run a tweeter and a speaker from a line which previously only had a speaker on it.

Given the coupe has a wire running up to the tweeter I thought that the replacement tweeter could be just spliced into it.

If that's not what they are for, what are they for.

Can anyone else help with this?

It's not my part of the ship either (although I'm not sure which part is...!), but I believe that the standard coupe tweeters have a passive crossover build into the tweeter, a capacitor at the back of the speaker. If you've bought tweeters that came with a separate crossover then they won't have one built into the speaker hence why you'll need to use the crossovers that came with them.

Gareth

So what do crossovers do then?

Please use the cross overs supplied with your components the fiat tweeters have a capacitor as part of them which acts as a very basic crossover.

Think of it as a boss it splits up the work so the big lumux woofer does the big heavy stuff and the little petite tweeter does the delicate intricate stuff and does not brake a nail.

Fair enough. I'd have thought that the cable coming out of the stereo would, if it was going to a tweeter, not put out the bass signal.

Clearly that assumption is not correct. I will install the tweeters with the crossovers.

You have one feed from the HU to each channel. Do you have the standard HU?

No its a Pioneer.

I'll use the crossovers.

haha this infinity is the stuff that was in my car yestaday mate

ok lets get this in writing

components packages use crossover as a means to filter the correct frequances to the right place, so in a most common component speaker packages its woofer and tweeter that produce the sound.

off topic
"also theres three way which consist of tweeter, midrange speaker and woofer speaker

but there mostly common on vectra's and up market spec bmw's but not really used as a uprated speaker option as 9/10 times doorcards need cuting and customising" dynaudio, vocal, alpine type x, and other.........

Anyway...........

so as for the job of the crossover, its job goes as the following in a componant setup of only 2

low and lower midrage = Woofer
Hi and hi midrange = Tweeter

the crosovers on some up market packages "i.e alpine type r componants" allow you to tweek them 0db down to say -5db sometimes more

but i alway leave them 0db as too much tweeking can end up being a wast of time due to how music is produced today and mp3's as one track will sound great once tweeked then others will sound crap but yes lets keep it simple.

now there are component packages out there that are CHEAP! £30 or so jobbies that use a tweeter with a resistor that cancels out the nasty frequencys and a woofer, "i.e alpine type e" but like i say its an improvment but not the next step up.

but band, model and quality is upto the end user to decide

and why components?

well co-axle speakers are just a all-in-one solution!
so there is a lack of tweeking as you cant position the tweeter where you want it.

this is called a "sound stage"

with a componant speaker package you can position it just the way you like it to sound.

hope this makes some sence

Very interesting Em.

Would there be a big difference in audio quality from mounting the tweeters "inside" the tweeter housing (i.e. the stock position) Vs positioning the on the top of the gril for the stock housing (as per the How To). I think I recall you went for the "inside" option?

If the latter is worth doing:
(i) will simply mounting onto the gril give enough damping/support (I just want it not to vibrate loose I don't need it to be uptimaltechnically)
(i) is a directional position on the tweeter going to make a difference.


Steve

The tweeters probably fit inside the old space but poke out the top if done right. this keeps them secure.

hi mate i had to remove the old tweeter's from the covers, then prise off the metal grills, then underneth there is a plastic grill that covers the old silk dome tweeter, bit of triming then the infinity metal grill covers on the tweeters are removed carefully, mounted on the newly retrimed fiat covers, gule gun into position, metal fiat grill back on.

wire them up, job done.


if you dont want to do them then give me a call

I'm not sure I follow how you are saying that gets done.

I have removed the tweeters and housing. The old tweeter has been removed. Metal gril removed.

However the new tweeter is too big for the hole in the plastic mount. I had thought of chopping a bigger hole in the plastic mount but I can not see how the new tweeter will sit lower than the metal gril cover if I do this.

Are you saying that the infinity gril covers can be removed and if this is done then the tweeter itself will not protrude from the top of the plastic housing of the tweeter body and can be glued onto the bottom of the fiat dash holder?

In your picture you have a tweeter in a pot. I used the same sort of thing. tweeter in pot pot through hole.

My tweeters are proud of the grill. Then you can see there is something there and that is probably how the manufacturer designed it. I pealed the inside of the hole until the new units fitted in them. I cut out all the fiat gubbins that is in the way and even sawed off the little tube like part so that I had a flat piece of plastic. if you work at enlarging the hole slowly you get a nice tight fit.
Then made a whole in the metal grills and fixed the grill to the plastic. then I pushed the tweeter assembly through the hole (in the two parts simultaneously) and the lip on the pot stops it going all the way through.

I'm with you. I had thought about doing this. Will be tricky though as the outer lip of the pot is pretty much the same diameter as the available space on the plastic housing. Clearly the interior of the pot is a little smaller, so the hole does not need to be quite that wide, but it will be very tricky to do this due to the size issue.

Guess I can give it a go though..

you have to get the raw infinity tweeter and magnet to fit in fiat tweeter position, but in order to do this the plastic grill that would of gone over the fiat tweeters inside must be removed

then position the new ones and glue, then reasembale

hope this helps,but looking at the these pic iv got kapper tweeters and yours are referance ones? so this approtch may or may not work

It works a similar way with the Reference Series tweeters, in fact I left the Fiat metal grille in place to avoid attracting the attention of any ne'er do wells who may have a look through the windows.....

I just cut away the plastic frame on the tweeter cover and used a hot glue gun to stick the new tweeter in place:

Thanks Em
Those infinity ones I have are significantly larger than the ones you have in your pic (don’t want to come over all “mines bigger than yours”, but it is true in this case – you could always claim your car is more powerful, but IU’m not sure that would help you here!). They have been a major pain to get into position under the fiat metal gril. However I have, with some manful persistence, managed to get the thing into place.
Question is though how to wire her up to check if she works. The stock wiring has a red cable and a black cable.
I assume red means positive, is that correct.
The wires coming out of the new tweeters are (I) red (ii) back with red stripe.
Is the red one positive and the red and black one negative?

Cheers

Yes your correct on that, that's how I would see the wires being but your only running the tweeters of the crossover not the woofers so that souls be fine

Operational. One down one to go.

Makes quite a difference, but potentially the system is a bit bright now - or perhaps before it was a bit bass and mid range heavy with the other non standard speakers.

Em, you might need to have a look at it next time we meet and perhaps make a suggestion or two.

The install I went for was inside the standard grilles, which is essential if you have the bigger tweeters. I think I might do a short alternative to add to Simma's how to for people who are in a similar position.

Steve

no problem i can have a tweek with you pioneer

haha just off topic, rog has a moonie gray coupe just like yours up at his place and phil the day before was going to buy another coupe due to the pace thing, but i convinced him to buy my set up and some more stuff of R1DAN, then after i bought the intercooler rog tells me oh the guy that owns that plus wants £2k! for it, phoned phil and he was so annoyed mate lol, i cant even drag him up ther to look at it mate hahahaha
