what do you suggest? I'm a big fan of rf. I know some people love them and some people hate them but i'm an old school guy so i guess rf has stuck with me since then. I know a lot of people use aq2200s on these. As far as electrical, i'm going to start with a big 3 then look into getting a better battery and maybe a higher output alternator later. I found out my stock alternator is 160 amps. I was hoping to get away with just a big 3 but if i can't, no big deal. I don't drive a lot (my office is a mile from my house) and the system will rarely be played with the truck not running, if ever. It's a daily driver.
