I kept the stock amp. I can't tell really, the past OEM speaker had the foam problem for quite too long that I don't remember how it used to sound. But the new one just sounds OK, it doesn't give that as much bass as I would've liked.
Appreciate the write up Mtnracer. It helped me a lot.
I went with the Pyle PLPW6D 6-Inch 600 Watt Dual 4 Ohm Subwoofer as a replacement. Wanted to attach a couple of pictures. I had to use a dremel to make more space on the box so the speaker would fit correctly.
