Hello, I have Two 15" Ma Audio XL. There hooked up to a kenwood 300 watt rms amp. It sounds ok but what amp do you think i should get I was looking at the JL 1000/1 amp. Save my money up and get it. I have a 2001 Grand Am SE how many dbs does it hit now then with a JL amp. Just a ballpark figure. One more Q&a what would be the equal to my subs they push 600 rms at a piece. Thank You
