Need help with audio setup.

[Israeli_Z]

I'm slowly ordering parts to complete my audio install. So far I have Polk DB6501's in the front, Polk Tweeters and Polk DB351's in the rear. I'm waiting on my Alpine INA-W900BT head unit and a JL XD-ACS60 wiring kit. This is the first time I'm doing a sound system and am not sure on what works and what doesn't, I hear that amping your speakers results in a better sound. I want to know what amp I can use for the front and rear speakers (not sure if you amp tweeters)? I haven't put in the crossovers yet because I haven't put in the head unit yet, I also plan to put in a JL 13TW5 and want to know what amp to use for that? I prefer to use a JL amp to match the sub but as for the speakers I wouldn't mind using JL (for a clean look) but if you can recommend something better that would be good too. I feel like I'm walking in the dark, so any help would be appreciated. Thanks!
