Kicker L5 15" Sounds Weird, What Could It Be?

[dawgs007]

I recently got a Kicker L5 15" in a custom (absolutely awful) sealed box. I noticed when I play at louder volumes, the sub seems to make a weird noise. (shown later in video) Could it be that my RF Prime 1200.1 @ 1ohm is causing the sub to make the noise? Thanks in advance guys!

Video: (the noise occurs at 0:01-0:03, 0:10-0:15)

Also, does it sound like a possible burnt voice coil?

How big is that hole the wire is going through. It looks like a 2 inch hole. If so that box thinks it ported. Tuned really high and creating all sorts of fun mechanical noise because it's unloading. What do your voice coils read?

The hole is 2.25" in diameter. I have since put a terminal in that spot. It still seems to to the noise shown in the video. I'll read the coils in a second and get back to you.

Is the box sealed on all the edges? Really hard to tell on a YouTube video what it's doing. If you turn it down a bit does it still sound like it?

U should put that thing in a prefab box and call it done. Jk

It sounds like its not fully sealed?

 

[dawgs007]

It seems to be pretty sturdy. I do believe the inside is also sealed with a sealant of some sort. The box's dimensions is (DxWxH) 13.5 x 32.5 x 23 . The box seems to be made by a complete nimrod though. The pieces aren't flush with eachother. I originally picked it up for $120 (sub and box).

If you watched the video, does that noise sound like something common with boxes that aren't fully sealed?

One of the coils reads: 2.2. The other coil reads 2.3

Take out the sub and check the spiders for rips and tears, push down the cone also to check for sound. Do a free air test, play it outside of the box, if it still makes that noise then its the woofer.

Spider looks good, no noises at all when pushing on the cone. I'll do the free-air test tomorrow since it's midnight and I don't wanna tick the neighbors off any more.

If you push down, no noise, check each part of the spider carefully with your fingers. If all is good then its with your amps, check your grounds.

maybe the sub is coming loose from the box. I had to tighten my screws today because they were coming loose and my subs were hitting against the box making a distortion sound.

Not sure what year L5 that is, but I went thru 3 L5 (I wanna say 2004 model) due to faulty glue on the spider. Kicker knew about it back then and were replacing them without question.

 

[dawgs007]

Alright, I'll look into the faulty glue! And I retightened the screws just recently, so we'll see if that changes it. Also, it's not the amp. The amp works flawlessly on my 2 12" RF P3's.

I'm going to say it's a leaking box or the sub is defective. It could be that typical kicker sound though.
