Scary monster sub trying to escape.

I'm starting to think that there may in fact be a monster in that box? //content.invisioncic.com/y282845/emoticons/ohsnap.gif.17c4c91be09a7a4a3995fb7145adac39.gif

WTF? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

lol sometimes you could smell the coils slightly

not all distortion can be heard from when not infront of the speaker.

^^ True, but also a lot of distortion is CREATED through the trunk opening if you just listen to them right there.. it's hard to tell either way..

Want my opinion? Set gains with DMM to rated power, won't have to worry about heat/blown subs/gross distortion..

I've heard people suggest setting the gains with a DMM and 50hz test tone. But I've heard other people say that doing that will make it not sound as good. I just kind of put on something and set the gains to a point where it doesn't distort anymore and have my sub level on my HU at -10 (goes from +6 to -24). Then I can go up or down from there, usually around -8 with the gain a little less than half. Like one notch down from half. The xover past half way (I use the LPF on my head, so I figure the one on the amp is useless.) And the bass boost just over half (a little past one notch up from half)

Also, I don't really know how to use the dadgum multimeter... I mean, kind of but not really. And I don't know how to generate a 50hz tone or if it would be better to use say a 30hz tone.

Does it make this sound when you have the rear doors closed or only when they are opened?

What kind of car and which way are the subs facing?

1999 Tahoe. Facing rear. Box pushed up against the back of the rear seat.

I only hear it when it's opened, but it's definitely the speaker, not the truck.

Turn the sub level on the deck all the way up and then reset the gain

What I am getting to is that the vehicle actually acts as part of the enclosure.

Tuning also depends on the cars interior volume so once you open the door you are raising the F3 of the enclosure.

Basically the air in the back acts as a spring and once you open the doors the air as the spring is let out and there is not enough suspension to control the sub at high volume.

Try climbing in with it playing and close the doors with your head near the subs.

Hmmm... never thought of that. I'll have to get someone to climb back there for me and check that. I'm a big ol' boy.

Yeah. But the chambers are sealed off from each other, so it's not like it's in a box twice as big as it needs.


I was just about to try to find out if I needed to set that. It seemed like it would rob the low end (cuts out everything under 25hz) You think it should be turned on?

It's in a sealed enclosure now, but I've got polyfill in there. Could that be a problem? I may have too much.

There is little to no music that plays much below 30 Hz, the "low-end" you speak of is in the low 30 Hz range.

edit: Just saw you have a sealed box. SSF isn't the problem. Sounds like you're overpowering (read: clipping) the sub. Learn to use a DMM. Read the guide on this site.

Good luck.

Do you have a midget on staff.

 

[RebelDogg 10+ year member]

No, unfortunately she quit after that little (no pun intended) "****** harassment" incident. Hey, it's not my fault her head just happened to line up with... eh... anyway. No.

But I do have a skinny friend who's probably only about six feet or so and less than 200lbs. Close enough.

Midgets are a dime a dozen these days. But a midget with a good ear is another story.

It's called setting it the correct level of gain. Unless you want to risk distortion, clipping, and a dead sub/amp, it's what you need to do. If you don't want it to "sound bad", go get a higher rated amp.
