make sure u wire that thing right...thats alot of power on one 10" sub...i know if u bridge it, the cone is sure to fall right on its face....!
as far as trunk rattle, i'm pushing some pretty nice power and only problems i have is my rearview mirror and my license tag beats pretty bad (can easily fix, too lazy)..but my GP holds the bass really well, considering how most of the cars around here sound...
