Muddy bass?
 
I am not a sound fanatic by any means, nor a bass head. I have never added a subwoofer, amp, or redone a whole system. I got my '12 Limited with the 430n system 2 weeks ago and I have noticed the bass is heavy but very unclear. I would like to know if the is an easy way to clean this up a little? Sound mats in the bass enclosure, or adding bracing to it maybe? Anyone else notice this or have any ideas?

Hi and seasons greetings,

Another forum member has a thread somewhere with pictures showing what he did. In summary, he removed the subwoofer housing which is plastic and add a plywood backer plate to stiffen the enclosure and then they added sound matts on the rest of the exposed plastic. In addition, a new 8 inch woofer was installed along with a small amp.

I will try to find the link for you. Also, if read the forum, you find other ideas as well.

Best for now. :)


Here is the link to that thread:

Thanks. I had seen Moose's thread I was just wondering what else might be done. I think I will try reinforcing the stock sub enclosure and adding some deadening material before I opt for new speakers or amps. All I am looking for is cleaning it up - not more power.

Hi,

It can not hurt to try by adding additional sound matts or other materials around the sub enclosure. Otherwise, their is nothing more you can due since you are limited by the settings and designs of the internal amp in relationship to the subwoofer (dual 2 ohm load) and front speakers.

Best for Now. :)

Here's the weakest link, Chryco's plastic sub enclosure. It flexes wildly with any bass hit, then causes a double bass hit resonance against other internal stuff, all of which muddies the bass notes.

+1, Docluv seemed to have success packing dynomat or other materials around this enclosure. Give it a try before dropping dollars on a solid fiberglass sub box or stealthbox and let us know how it goes.

I find myself wondering if anyone has made a plaster casting of this factory enclosure, then created a solid fiberglass/resin copy/replacement?

Moose - Thanks for that. What do you think of maybe cutting some dowels and wedging them inside the enclosure, maybe with some Gorilla glue on each end? That should add some decent structural rigidity without too much extra effort. Heck, maybe even run some screws into the dowel from outside the enclosure. Since any cone movement would want to expand or contract both sides at the same time, internal bracing should help a lot, no?

Looking to tackle the sub bracing next weekend. Does anyone think it will / won't help? Not really interested in doing the amp/stealthbox thing.

Also it looks like the whole side 1/4 panel trim has to come off to get the sub out. Is that right?

Keep me posted. I normally are full systems to my cars, but this will be the wife's in a year, so I am saving for my next car. I am looking to do the same thing this winter when I have some spare time.

Not to be negative but i dont think putting internal bracing will help much! I dont have a stock sub so im adding one soon but good luck with cleaning the bass up a little!!

Not at all, if you think it won't work I would like to hear your reasoning. I certainly don't want to waste my time if people don't think it will help.

It should work. You don't want the flex in the box. Regardless of what you do to dampen the sound, you still need to shore up the box to make it more rigid as a whole.
