Could someone please help me with a question. I purchased a JVC KWR 500 hu, a pair of Infinity Reference 6032cf 6.5, and a pair of Infinity Reference 9633cf 6 x 9 from Amazon for $222, and will recieve them on 11/26/12. My ? is, will these speakers work well off the hu without an amp, and does anyone know if the sound should be clean/clear sounding at a moderately high volume setting? Maybe, I should have looked more into it before purchase, but I've done it now, and know nothing about car stereos. I thought you just bought the radio & speakers, and they just work...from what I've been reading online, that's incorrect. I'd prefer not to use an Amp, but will if I have too. I haven't found anyone posting results of coupling that JVC hu with those Infinity speakers, worrying if there is a reason why.
