OK I've narrowed it down to these two:

I saw a US acoustics 65wx4 for $130 and it can go 3 or 2 channels as well. (I can ad a sub later).

Questions: how long would my speakers last on 65w rms? A year? Forever?
Remember: Altec components: 40w rms (guessing)
Pioneer 6x9: 40w rms

Or

I can get the JBL 80.4 that is 40wx4 and also goes 2/3/4 channels for $140
