sound like crap, and they only play quietly. So if the polarity is reversed I will know as soon as I play music.
Right now I get very little bass from my 4x6's and my 6x9's. My 4x6's do not handle any bass at all.
My 6x9's are Kenwood KFC-6982IE
My 4x6's are Phoenix Gold Ryval V460
I thought I would have to cut my doors up to fit 6.5's in them, but it looks like I can buy a cheap adapter or even make my own.
