at high power tweeter cuts on and off, can a voltmeter test the wire

so at full power my tweeter cuts in and out like it is over heating. can i use a voltmeter to test the wire going in and out of the tweeter? what setting should it be on?

the setup is botson acustics ralley series and the crossover is good (one went out once, gf slammed the door too much). the componets were professionally installed along with the deck.

Set meter to ohms and the tweeter should read 4,6 or 8 ohms, I dought the problem is the tweeter I would look at the x-over, easy check switch the x-overs, if the problem moves to the other side, there is a problem with the x-over, if it stays on the same side, then it’s the tweeter or the wiring from the x-over to the tweeter or the connections. :hmm:

Are you using the factory deck to amplify the tweets? or do you have an external amp? And how do you have tweets hooked up? Crossover? Sounds like the amp is clipping. The only thing you can really test for is the speaker impedance with your multimeter.

Give us some more information on your setup.

i have an alpine v12 that is like 225 x 2 or you can push it 500x1 . the amp is a 1999 model. i have a sony mp3 8000 series (kinda new) and the boston acustics ralley componets were installed by circut city. the crossover is in my door in bubble wrap, wraped excelent. it does sound like the crossover and you guys have given me a few things to check since i have a 20 buck voltmeter.
i ruled out the amp by switching right and left RCAs. nomatter what it is the same tweeter that cuts out .

THANKS and keep giving input, tomarrow i am looking at it and will write more.

RacingPoverty - cool, sorry

Some components have built in tweeter protection in the crossover. You say this only happens at high levels, so it could be the protection circuit coming on.

I agree with Steven :up:
And if the x-overs are inside the door :tsk: :worry: :roll: that is a cheep cheezy way to install the x-overs, the inside of your doors get wet, real wet sometimes, and unless they are installed in waterproof containers they will at some point also get wet, they also need to dissipate some heat, so if they are all wrapped up, it will be hard for that to happen :hmm:94

circut city did the install. i will know better next time. they are made waterproof but heat might be trapped.

so yesterday i was checking the wiring and writing you. i undid the tape on the 2 wires that go from the tweeter to the crossover and checked the sauder. after retaping it i aparently fixed it. when i went out there today and had the multimeter set up to the crossover i never could get it to cut out agian.

these things get me pissed because the cutting in and out happened for a few weeks till i had time. now when i have time it is too simple. i bet when i get busy it will happen agian. i need a new saudering iron but i am planning on handeling this soon.

Dude, a new soldering iron is like $7 at Radio Shack; just disconnect the wires and re-do your connections while you have the time.

Switching RCA’s at the amp doesn’t rule out anything; all you did was change the channel from L - R on the INPUT stage, but that doesn’t affect which channel in the amp is feeding which speaker; that has remained unchanged. Just FYI.

Good luck…

Yeah, it sounds like you had a cold solder joint. Make sure you heat up the parts enough that you are soldering together. It should flow evenly, not clump up.
