So I currently have 2 sa15s on a taramps 3k
I’ve had one woofer for over a year, and other for about 7 months and I want to say they sound fantastic. Thought about going with SKAR but happy I stuck with sundown.
Anyway, I’m having an issue with both subs making a rattling sound. Like a penny in a glass bottle type sound. Both subs are doing it, the sub I’ve had for Over a year has been doin it for about 6 months. I’ve since reconed the woofer and it still makes the sound. I’m getting ready to recone and upgrade the system (meaning build a custom box instead of 2 separate boxes, and fixing this damn rattling noise). Doing the recone on both because my newer one is on its last limb. I ran them on a skar rp2000, where I was reckless with listening volume, then a cheap
amazon amp where I was also reckless with the volume.
the rattling isn’t audible from the drivers seat at regular volumes at all, and they still pound. It is audible at low volumes from my seat though. When you open the trunk it’s audible at all volume levels.
so it’s persisted through multiple amps and Has been happening for months.
so things that I know it’s not, voice coil, box, and amp being I’ve tested it or changed it out with no difference in the sound. Is it common for the magnets to vibrate loose after prolonged and excessive abuse? Like extreme abuse I honestly beat the **** out of these woofers I’m not gonna act like I don’t. I’ve blown 2 rp200s up on these subs, so extreme abuse. If I shake the hell out of the subs sometimes it will do it.
Also, I’ve read at about interference between rcas and power wires. I’m running 0awg ofc Rockford Fosgate power and ground. Rcas ran directly beside them, actually zip tied to it the whole length of the vehicle.
any help is appreciated, thank you for taking the time to read this all. Just want to figure out what the problem is so I can decide next steps for the project.
