This thread got me curious, so I looked.
https://www.bestbuy.com/site/geek-squad/car-electronics-professional-installation/pcmcat59600050005.c?id=pcmcat59600050005
2 ch or mono amp, $99.99
4 ch amp $119.99
pair of speakers $39.99 or $64.99
So best buy would charge $300-$350, and that's for a basic amp and speaker install only. They don't even have a listing for the big 3, and Id be surprised if they didn't offer it. I would certainly think you would need it, if not already done.
