I was wondering if i could swap out the 10" sub woofer in the back and the stock amp for a bigger amp and a bettero sub and what would i have to do to do all of this.

 

You should change the Box too and just go 12 inch. And Audibahn is my favorite company, but you should do a good some company like Rockford or a brand name. But i think you should look to see what you have to work with, you probaly figure it out like that.

 

I would recommend kicker def the best bang for your buck in my opinion.Ebay is always a good place to find a good price on a system.
