wasup yall. This is my first time on the site. I been looking around on it for a while and now decided to post.

Alright so I just got a 2001 reg cab 150. and i want to put some thump in it.
I was in my buddys 150 which was pretty much identical to this one and wen he turned the base up I thought the switch on the dash that he fliped was for a massage pad, turns out it was for the base.

I dont want it that loud, but i want to feel the music as well as hear it. wat do i need to change?

I have a mechanic friend who knows all the local vendors so he can get my some sweet deals but i need to know wat to look for wen i go with him.

2 12's, wat size amp?, new door speakers? tweeters? wats the thing called to keep my battery from dying? and do i need that?

thanks
