should be plenty....i have a memphis 500d mono that puts ~700 watts @ 2 ohms on a diamond audio dvc 15 & it fuking pounds
last week i had to goto a windshield repair shop to have my rearview mirror professionally glued back on cause i had vibrated it loose & the crap @ autozone just wouldn't stay glued on. :thumbup:
