this thread seems to be a good one i am enjoying it.
its amazing to see all the mis-information out there
basically i agree with curley 55 deck power sucks some are better than others but if you want to here all the music the way it was intended get a good amp with good speakers(speaker opinions as we see are at the least varied lol)
some things i look for in an amp
the manufacturer ie: quality control, warranty, yrs in bussiness
what imput voltage the are basing the output in RMS
THD less than 0.5% at rated power @ 2ohms. BE SURE ITS FROM 20-20K HZ anyting less is B.S.
damping > 100 db
ihf dynamic headroom +3db or better most mfg. dont disclose this
signal to noise >100db
separation >90db
build quality/ what country of origin
these are the basics for me. there is more to look at, like if it has crossovers, bass control, etc.
