You'd think when you shell out some big $$$ for a truck you'd get more than paper speakers in our trucks. Not so. I have 3 teen boys and it was becoming a problem with the volume up. Solution? Infinity Components in each door and a 5 channel amp with 2 10" subs under the rear seat. With the Christmas sales it wasn't a huge expense and now everyone is happy!!!
Rock On!!!
PS the stereo in our trucks do not have pre amp outputs so the amp you buy will need speaker level inputs.
