I put in my Alpine DDDrive components about a week ago. Everything sounded good for a while until my right tweeter quit playing. I didn't even think anything of it at first because I thought my brother's leg was blocking it. Anyway, changed out the tweeter with another one that was given to me and it worked fine. Then the one on the driver's side quit working. I don't have another tweeter to replace it with either. Any ideas? Maybe just a bad connection on the tweets? The thing is, I can't get to the connections to check. Plus I bought them used so they're not under warranty. If anyone knows how to get into them, let me know. I'm pretty good with a soldering iron. Any other ideas would be appreciated, too.
Thanks,
Jeff

Hate to bring bad news, but they sound pooched............ What's driving them?? An amp I hope. It's real hard on components running them off a deck. Plus the Alpines don't have any protection on the tweet....

I was going to add to Dukk's response. He already made the valid point, Alpine does not protect they're tweeters. You must do this yourown self! Dukk had advised me to use 12v light bulbs in series to protect my tweets, which, by the way, have been installed. They kinda give a pretty glow under the dash....

Yeah... Blown subs often still make a noise. Either you've broken the motor mis-aligning the driver or you've partially burned or separated the coil. Blown mids sometimes make a noise. The above things can happen but it's a little easier to leave the circuit open. (totally fragged coil) Blown tweets usually just quit. Generally the failure is a burnt coil or where a wire comes off the terminal to go to the coil.

As far as the light bulbs, I bought a couple of blue ones to match the interior. Should look nice if they light up even a little. Anyway, how do they work? Wired in SERIES, right? I assume they just use up a little of the current going to the tweets, but wouldn't it still be possible to blow them? Or would the light bulb burn out first? I saw these things in Parts Express that completely cut off the power going to the tweets when they get a certain temperature. Anyone know off hand what these are? Are they better than the light bulbs? Once I order the new pair and get them put in, I don't want to be going through this again. Thanks for all your help.

I like the bulbs because they also filter out odd spikes and noise that may prematurely smoke a tweet. While a bulb does rob rome power all the time, it really doesn't affect to much until it begins to light up. Once making full light it pretty much burns off all energy past that point. Generally with a 12V bulb, this limits the tweet to seeing around 36watts (plenty) more or less. If you want more power flow to the tweet then use combinations of 12V and 6V bulbs. Many major home and car companies use bulbs for tweeter protection. Their less prone to failure than small breakers or fuses, and are simple to use.
