i am looking at buying a vibe cbr100!!! in the shop they said it had a amp built in and i wopuld not need a amp to run it off. is this true? or do i need another amp to run it from??

if i need a amp will a sony xplod xm754 4x170w max 4x75w be enough to run the sub AND my two pioneer 3way 300 tsa6995 6x9s?
