equalizers just open you up to a world of problems like engine whining and extra noise, especially if it is a cheapy no name brand, just get a good enough amp that comes with a built in crossover and you wont need an EQ, and alot of the newer amps come with remote bass gains to adjust the level of bass on the amps which is the same idea as having an eq to adjust the bass
hope that helps
