I enjoy both and look for similar things from my home and car system. Obviously what can be done and how they sound are dramatically different. In cars I generally spend 2-3k and can get a very nice setup. I always start with amplification and then add in HQ front speakers. If I have the budget a sub is the last thing to do and rear fill speakers.
Yes all too often people just add a sub to a stock setup which sounds just awful. But a good setup with more power and better separate drivers can really sound and image well. The imaging is unfortunately somewhat driven by existing speaker locations. I also stick to OEM head units (lossless music on USB) and stock speaker locations so setups are stealth. I do longer drives fairly often so a good rig in my car is important.
