Speaker cuts -in / out

Hey there - I hope someone can give me some advice to troubleshoot this problem:

I have a midrange driver that cuts in and out all the time. I checked the connections at the speaker terminals (soldered - looks good), and the passive crossover screw terminals (looks good). I know I don't have an issue before the crossover because the tweeter never cuts in or out (tweeter is spearate from driver) and is run off the same channel.

One peculiar thing is that whenever the speaker has cut out, it will come back at high volumes...

Any idea what is happpening here?

Thanks in advance.

I suspect a blown capacitor in the passive crossover?

Easy to test. Bypass the crossover, by attaching the midrange speaker to the input wires. Don't go super loud because your mid won't like the high freqencies. This will tell you if the speaker is good.

if it was the cap I think the tweet would be kicking in and out

Edit: removed my answer in its entirety

EDIT: re-read the Question... not the HU like I said ...but it is the driver itself or the crossover assuming all the connections are good. Use Dukks troubleshooting guide below

Im having the same problem started last night. Let me know if you find the solution.
At a lower volume does yours distort and kind of gets louder, then quiet than loud again? than when u crank it, its stable, but pops at the peak notes?

here's a problem I had... I ran the speaker wire on the outside of the door molex and it was rubbing against a sharp edge of the door. cut through the insulation and then caused intermittent problems (noise in system, cracking, popping, amp went into protect) So, make sure the speaker wire is good all the way.

yea mine are good, its the rear speakers. theres nothing interfering with the wire. Im trying to figure out..is it blown? about to blow? or is the amp ****ing up causing the distortion..

If it plays loud but not quiet then I would suspect a bad solder, cracked trace, or mostly burnt voice coil. Trade your mids side to side to see if it moves with the mid. If not, trade your crossovers side to side to see if it moves then. If not, trade speaker leads at the amp side to side. Then trade RCAs side to side at the amp and then finally at the deck.

Process of elimination.

I'll try a resolder first this weekend. Thanks for all the input so far!

I thought it might be a burnt voice coil but the speakers are new and I have not punded the crap out them and I have an appropriately matched amplifier powering them.

why not just crimp some connectors on? and check the speaker wire all the way
