Hi, i was wondering, before dismanteling both door panels in order to see if the tweeter is just blown or if the cross-over just went out. My Right front Infinity Reference tweeter has no sound what so ever coming out of it. it was working fine up until i noticed a different sound in my car. & i realized my tweeter wasnt working.
My questions is: Do you think it is blown? or maybe the cross-over? & is there an easy way to finding out?

You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.
If there was a traumatic high-volume event that preceded this problem, I'd guess the tweeter died.
If you can access the connections on the tweeter and you have an ohmmeter, you could disconnect the tweeter and measure across the the terminals. A shorted or open voice coil = dead tweeter. A measurement near the stated impedance is probably ok.
If you have NO ohmmeter, you could carefully connect the output of one amplifier channel directly to the tweeter and just scooch the volume upward slightly from silence while playing something with very little bass in it. If you hear it, the tweeter is alive.
Could be an open capacitor in the cross-over, unconnected wire to the tweeter (not likely) or a blown (open) voicecoil in the tweeter. Remove the tweeter and with a 9 volt battery (even run down but not dead will work) quickly touch it to the connections to the tweeter - it should pop and crackle. No static, the tweeter has sung it's last song.
The crossovers in professional speakers don't fail that easily. It could be a blown tweeter. To confirm remove the metal grille-- remove the screws of the Horn Tweeter -- remove the cable connectors on the tweeter terminals ( Red and Black wire ). Now if you have a multimeter put it in Ohms range and touch the probes on the tweeter terminals-- It should show a reading betwwen 4 to 8 Ohms depending what is written on the back of the tweeter magnet. If you do not have a Multimeter you can take an ordinary cell/battery ( 1.5v ) from a TV remote and touch the terminals of the Horn Tweeter with the battery. + to the tweeter + ( a small red dot or mark will be there on the tweeter ) and -- to the tweeter -- . When you touch the terminals or give 1.5 volt supply the tweeter will make a scratching noise. If you do not hear the scratching noise - it indicates a blown tweeter coil and will need replacement.See link below for spares:- http://legacysoundservice.com/catalog1/product_info.php?products_id=1417 But if it does, you are in trouble and will need professional help from a electronic technician. Could be blown HF Amplifier, suspect the crossover last. They seldom fail. Revert back for more help
either the wires in the boot where door folds open has broken wires in it or the most likely case you have 2 blown wolfers and 1 blown tweeter. common for cars with the monsoon stereo system, they made the radio better than the speakers.
the best solution I've found is this: 1. Remove all the tweeter screws. 2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.
This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.
The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.
hi, have u first disconnected the tweeters and then checked, as if its on a cross over, the tweeter is in series with a capacitor,if u have a ohms meter or a continuety tester check the tweeter coil if its open,secondly you can have the coil replaced, check if u can get one before buying a new,let me know
