Denali Sub and Amplifier

[98silveraydo]

I found a 00 99 center console in a Denali with the sub and amp in it. I already took the sub out of the little box it was in. My big reason for the center console was so I could keep the room behind the seats, I have a reg cab. Now is the amp and sub any good? I also have an 8 inch JL I wanna put in there a friend gave me for free, never been used. Could I use that amp for both subs or should I get something better? I don’t know enough in audio. I think what I really want to do is get another matching 8 inch and put in there and get rid of the Denali sub. What kind of an amp would I need for both the 8s? Could I keep the Denali one or do I need something better. Not looking for the hardest, loudest bump, want a clean bass hit, why I went with JL.
