I tried the kicker sub based off info on here I was so unimpressed with its performance I sent it back I highly recommend trying the quadratec sub. With that said I did neither I fixed my existing sub and ran window urethane around the foam bead that was broke and it hasn't missed a beat yet...cost of doing that FREE!!!
What type of Urethane did you use, some black auto windshield stuff from auto parts store?
This is getting annoying not being able to post pictures cuz its above the forums size limit. But the stuff is BETASEAL U_418 quick cure primerless to auto glass urethane adhesive made by Dow automotive. Remember this trick may not work for all situations but so far mine has held like this for a year and a half...knock on wood

For a brief period I had an elemental designs EU-700 in the center console (before the kicker existed). Having a nice aftermarket sub is going to sound light years beyond anything you can do to the factory sub or with a cheap replacement.
I just finished replacing the stock sub with the one from Pyle. I believe it is better than the Pyramid and the Kicker because it is a true dual voice coil. With the other mods I've seen, they only use one side of the amp. This takes advantage of all the juice the little stock unit makes.
You can use any of the walkthroughs that have already been done, it's pretty much straight forward. It is a thicker speaker, so cutting the fins from inside the box with a dremel or razor blade is necessary to make room. You also have to drill new mounting holes on the inside box to line up with the speaker. I didn't need any other hardware other than I used some speaker mounting tape under the speaker rim. I also filled the box with polyfill.
Sounds awesome. Obviously if you want more bass, you need a better speaker and an external amp. This is just a $20 mod that sounds better than the stock one.
