Tony...
You should choose the models that you want. Each brand as a bunch of different models. What someone else likes, you may not like...and vice versa.
This is what I like...when on a budget.
Decks: Alpine, Clarion, Pioneer/Premier
Speakers: Infinity, Focal...Kicker and Pioneer have been putting out some O.K. stuff too
Amps: Soundstream, Kicker, R.F.
Subs: Kicker, R.F., Focal, Eclipse, ID's, JL Audio...Audiobahn is cool, but the SQ is so so.
All these brands have affordabel models that should give you what you need.
If budget wasn't an issue...this list would be completely different.
