I have a 2008 dodge ram quad cab and I'm leaning to putting 8s in it but also thinking of 10 for subs but need to replace the rest of the system first. wondering what head unit to go with and what dash and door speakers to use. head unit I have no idea but the speaker iv been thinking of cdt, alpine, dls, morel, or even orion but not sure yet and yes will need a 4 channel amp, subs thinking vfl 8, dc m3 8, sa e8, or the orion xtrpro 10 with the amp I have atm which is a aq1200d need some major opinions, suggestions, on any or all of these. funds I would like to stay under 150 to 200 per set of speakers and about 200 to 300 for the 4 channel amp. head unit is up in the air since I haven't had to buy one in a while.
