How do I choose the right amp for my new head unit and speakers?

[Bannahfa]

Hi! I'm new to car audio diy and need some guidance. I got a new head unit for Christmas, and speakers, and all chosen randomly. I have searched everything I can think of online, and I get more confused every time. Do I even need an amplifier for the speakers, but if I do, do I need a 4-channel or a 6-channel amp?

Head Unit: Pyle PLDN74BTi, 320 Watts (4 x 80W),

6 RCA jacks for amp: Left In, FL Out, RL Out, Right In, FR Out, RR Out.

Speakers: 2 - PYLE PLG3.2 3.5-Inch 120 Watt Two-Way Speakers (on dash),

4- PYLE PLG6.4 6.5-Inch 300 Watt Four-Way Speakers (on four doors).

Thanks for any help I can get.

4 channel will be fine use 2 channels for the 3.5's and the other 2 channels can be used for the 6.5's. wire each side "pair" of 6.5's in parallel for a 2ohm load per channel 3 and 4..

I appreciate you not ragging about his equipment, and offering decent advise.
