Rattle from HDS210

[UGHH]

I've had my subs for about 2 weeks now and a couple days ago and started hearing a rattle and I'm pretty sure its coming from one of the subs. I have a Plymouth Breeze and have the box facing into the cabin so they fire into the car when the back seats are down. I've searched around where the rattle is coming from and I'm almost positive it's from a sub. Anybody know what it could be? It sounds kinda like plastic, maybe the dust cap is loose? They still pound and sound good, there's just that dam rattle. It's annoying. Lol Any ideas?

What would cause that? They're not being over powered at all. Distortion, gain to high? My buddy installed them, set the gain by ear.

Cool thanks. If it is coil rub, will it stop if doing it free air? Or be worse?

It will allow you to see/hear where the noise is coming from. Free air on low power and see if its making a noise if so then toss it or recone if that's even an option on those subs

I read that I can push on the cone and hear a scraping if there's coil rub. I just did that and didn't hear anything. Although I didn't take it out of the box yet, but I didn't hear anything.

Usually but still try them out of the box to verify. Make sure not to give them too much power free air. Is your box solid? Possibly something vibrating apart

Yeah it's solid. Built by a guy in my area that's been building for years, I did think of that too though. I can hear the rattle better at lower volume, the bass at higher volume drowns it out. The rattle isn't loud, I just know my cars noises so I know it's there. I'm hoping it will be covered under warranty if it is coil rub. Only had these subs a couple months and only been installed for 2 weeks.

could be ripped spider, most of the cases, the rattles are comming from a damaged spider because voice coil rub is very apparent.

Play the sub outside the box already and you should be able to locate what is failing. IF the sub plays without mechanical noise outside the box the issue is with the box.
