Subwoofer Doom

I'm looking at putting the downfiring trunk enclosure for two 10" subs in my YJ. I am scared to DEATH of cabin rattle due to the bass though.

Jeep info:
92 YJ
Bare metal tub
Hard top w/ full metal doors

Questions:
What are potential problem areas for rattles and noises?

What has everyone done to eliminate their noises?

I should probably buy a replacement carpet kit, right? (what's the best kit for ~$150??)

I already have an inline amp on the way for my Rockford speakers... How will I wire a second amp?

How should I run the wires and hide them?

when it comes to rattling your just going to have fix them as you hear them.

rather than getting a new carpet you should rhino line the tub.

they make multiple amp wire kits to wire everything together.

I second Jma20a, you won't know your problem areas until you hear them. The bedliner inside, and I did my inner fender/ wheel wells thick with bedliner. Not only helped with acoustic performance, but made my jeep sound better going down the road. I can sometimes hear thoughts,haha

The rhino lining has nothing to do with the acoustics in the jeep.

I did bottom and inside of my tub for many reasons including easy clenup, however it did improve the sound of my stereo. If you don't know don't reply hateful $hit man. If you reduce road noise (as good as you can in an open top jeep) it will improve the sound of your stereo. I have more music now than mud terrains humming on the pavement. The acoustic sound stage of the jeep is only cabin space, I am a proffesional I understand that. But sound dampening is a key to good performance when it comes to your mobile audio/visual devises.

You're right, bedlining will dampen sound. A thick, heavy coat of paint on metal, will obviously dampen sound.

In answer to the OP, there are molded subs available for Jeeps. The best ones are down firing. I have the Thunderform one for my Jeep. But, it is for 97-06 Wranglers. I found this one for earlier model Wranglers. With subs you need high RMS. It is best to have 400watts and above. I found this one for earlier Jeep models. It is Marine Enclosure for off roading too, and down firing. 375watts RMS, which is good.

I'd say you're both right.. Rhino Lining or heavy paint on the tub will reduce acoustic resonance and road noise (probably not as much as carpet though), but won't do anything for acoustic reflection as it's still a hard surface (where carpet would be best for acoustic reflection). Why do you think movie theaters have carpeting hanging in curtain-like structures on the walls? Acoustic reflection elimination.

That being said, I'd agree that you'll have to deal with rattles as you incur them. If you put carpet in, you may not hear any rattles at all (I have carpet and no rattles in a TJ)
