Currently I have the Sony CDX-M3DI (http://www.xplodsony.com/products/?CATEGORY=CD&MD=CDX-M3DI) installed in my car. Sitting in boxes I have the Alpine Type-R 6.5" Components (http://iweb.alpine-usa.com:7777/pls/admn/item_info?p_item_name=SPR-176A&p_category=80&p_subcategory=90&p_main=10) and the Type-R 6.5" coaxials. I want to put the speakers in but I'm not sure if I should get an amp first. I'm new to audio, but it seems as if the Type-R's have max output of 50W and my headunit's amp can hold up to 52W.

My question is, do I need to buy an amp first? If the answer is no, how much of a difference will there be between using my headunit and using an amp such as the Alpine V12 4-channel.

Thanks for your help.

Head units cannot properly power components. It is definitely advised that you amp your components. Anytime you amp a set of speakers, they sound much better and won't distort as much when you turn up the volume. That 52 watt rating isnt really 52watts RMS, which means its not constantly going to produce 52 watts. The alpine type R components is 50 watts rms, which means it need at least 50 watts constantly to sound great, its pretty much recommended you throw at least 50 watts. But i'm pretty sure those components can handle more up towards around 100 watts. Then they'll sound awesome. Clean power is a must when you amp your components.

i had a head unit that said it put out 25w rms and i ran coaxles off it for a few weeks when i didnt have money yet for the amp... got the amp (30w rms) and they sounded twice as good at every volume... never did that to my components, though, but i think the difference would be even greater
