A couple months ago my step son got his bought his first nice car, a 2008 5.7 hemi charger. He brought it over to show us and it wasn't but 30 minutes into talking when he said he wanted to put some nice music in it. Naturally I was thrilled He's been playing guitar for about 12 or 13 years so he has a good background in music, but never had anything remotely serious to listen to. After he spent some time in my charger he knew what was achievable so was willing to put in some work to get.
The goal build wise was to not go too crazy (like mine), keep it budget friendly yet be a big improvement over stock.
With that in mind, we worked out the following equipment:
A new Clarion HU from Crutchfield, which of course came with the mounting kit.
A mono alpine amp from several years ago that he already had.
A new 4 channel alpine amp for the front
An Arc 6.2 component set I got in a raffle at Erin's GTG a couple years ago that's been sitting on my shelf
Sundown SD-2 8" sub
The new JL Audio Twk DSP. I was a beta tester for the unit so I had it on hand and it can't work in my car so we put it to use.
And of course new distro blocks, fuse holder, wires, etc.
I let him do all the sweaty work while I guided and mostly watched
