Hi all. I just finished getting everything in and I am now amping my JL Audio 3.5 inch fronts, my Alpine 6 X 9's in the back, with an old Alpine amp, 50 watts RMS x 4. My question is, whats the best requency to set the 3.5's and 6x9's at so I can get good sound quality and the least amount of distortion possible, but I want a wide range of frequency's to be heard, basically the same quality of music you would hear from the deck, but if you crank it, you get no distortion, after all that is one reason we amplify and filter freq's right all? Also for the subs, what is good, about 60?? thanks! I just want good sound quality, but yet a loud system, clean, crisp clear bass
