"You got some choices here. First of all, you really won't be happy with the sound coming from your components unless you amp them. You can either buy seperate amps for sub and speakers, which many people do because of the bling in your trunk (I mean, 2 or 3 amps does look pretty impressive), or a single 5 or 6 channel amp that powers everything. I don't think an active crossover is in your price range just yet, so I won't worry about it for now. I've got a DEI 1100d5 5 channel amp, that puts out around 1100 watts, ~ 75 on 4 channels for the speakers, and 600 at 1 ohm for the sub. I'm not touting Directed, I'm just going to try it out. Hifonics makes some really good amps, PPI is a good brand, Pheonix Gold amps are really good, and Profile makes some nice ones for the money. Depends on how much power you want. "
I just bought components and your saying if i want better sound i should amp them?
