is that the only one? and do they have good brands in there or is it a bunch of pyle and hifonics $hit. do they have dd, audioque, treo, memphis, fi, RE etc...
That's the only one I subscribe to, I'm sure there are others.
They don't talk about a lot of crappy brands, most of the stuff they test fairly good at least. Their opinions of products they test have to be taken with a grain of salt though. I only read it the cold hard data (amplifier bench tests and the like).
It's been a while since I seen them gut they might still be out there. I believe it was Autosound & Secutity magazine and thre was CarStereo Review. Both I thoght were very good.
