What car audio? (bang for buck)

[Shonver]

I'd like to know which manufacturers of car amplifiers are reputable these days. The brands I see are not familiar to me, so it seems I'm very much out of the loop these days. I am in need of a 4-channel amplifier. I am not in the market for a high end product, I just need it to not suck. Something reliable, too.

Perhaps as  start I can name some that I see around:

Pure Audio
Star Sound
Energy Audio
Power Acoustic
XTC
Powerbass
Digital Design
Targa
Calibra
Audiobank
ICEpower
Harwa
Lightning
Dixon
Phoenix Gold
