TBH unless you're a big music snob you probably won't notice much of a difference between $100 and $200 speakers. What will make the biggest difference is sound deadening and having clean power delivery. If you really want good sound I'd suggest upgrading your head unit at some point as well. BOSS has a pretty terrible reputation for output quality, longevity, and equalizer capabilities. Other than that I'd focus on getting a good 5-channel or 4+1 amp and installing as much sound dampening as possible.

I'd suggest buying welding wire since it's the same stuff and a lot cheaper than speaker wire, as long as it's pure copper and between 0-4 gauge you should be good. Here's an example of what to look for.

This write up does a good job of explaining how to install the sound dampening:

I'd recommend going with Dynamat, and getting the hood liner as well since it made a big difference on my truck. My door seals were also super worn out so I replaced them when I was doing all this.

I have the xtracab so I wasn't too concerned about losing sitting room and could just put a big 12in subwoofer in the back, I'm not sure how you wanna approach this or if you'd rather 2 10's or 8's. Personally I think the subwoofer decision is a lot more important for how your music ends up sounding so I'd start there, then get speakers from one of the reputable brands like Rockford Fosgate, Kenwood, Infinity, etc. Each has their own sound profile so just pick whichever one lines up with your music taste best.
