Help with stock replacement sub using factory box/wiring/head unit

[Ledesordre]

May need an electrical/stereo guru to chime in.

2001 Tahoe LT with NON-Bose OEM stereo with factory subwoofer.

Factory sub was blown so I put this one in the stock box:
Polk Audio db840DVC 8-Inch Dual Voice Coil Subwoofer (https://www.amazon.com/gp/product/B0016GV1UU)

Upon getting it installed it sounds bad, the speaker is creating a lot of buzzing/rattling noise.

My question is whether the Polk sub that I put in brand new was bad, whether I have it wired wrong (ie should it be set up for 2 ohm or 4 ohm?) Is the Non-Bose factory deck/amp capable of running that?

Anyway to test the sub to see if it is still good?

Thanks everyone, can upload a youtube video of what it sounds like if that helps.

All right so i pulled the Polk subwoofer back out the factory box and took a look at it. I thought i'd update since I resolved the issue and I hate when I look at a forum post and someone has a problem and doesn't come back when the resolve it. Anyway--

It was the fact that my crossover wiring to wire it for 2 ohm instead of 4 ohm was pretty poor so it was causing noise. I re-did the connections and all is groovy now.

Did that link to Amazon redirect to the same item on Walmart.com for anyone else?

Yes. Thought it was odd.

Saw another thread where it did the same thing. I thought my computer was infected with some kind of malware, but I had a buddy do the same thing and he had the same result.
