The only downfalls to the stock are:
*Thin injection molded plastic (not the best sound quality)
*Limited airspace and mounting space for upgrading woofer
*Make sure you find the enclosure, plus the carpet facade piece as well.
But they are a super clean and easy installation.
Now if you were planning on using the stock sub, amp, and enclosure, you need the wiring for the car, and that gets to be very labor intensive, but just using the enclosure is very easy.
I really don't need anything hard hitting. I mostly listen to metal, I only listen to hip-hop on occasion. I've never had subs before, but if I get it I want it to be something that doesn't take up space and looks bone stock so it doesn't get messed with. The stock speakers in my Ranger with an aftermarket deck were fine, I think I'll only get subs if I still don't like the sound in my Focus after replacing the deck.
