I had a car audio store install a 4 channel Sony Xplod amp to power my two front and two back speakers. Today I noticed something odd however. When I turn the gain knob that says "Rear Level" it actually affects the front speakers. And when I turn the knob that says "Front Level" it affects the rear speakers. Is this anything to worry about? Also what could cause this? I also wanted to note that for some reason my front speakers sound less loud and powerful than my rear speakers, like as if there's more power going to the back one's, when both are at the same level on the knob. I can turn the gain knob thy controls the front speakers higher than the one for the back, but this concerns me. Are the back speakers sometimes louder than the front. Are they supposed to be(sorry for noob question)? Both pair of speakers are Alpine type E, the back ones being the 1725s a the front being the 1750s. Any help is appreciated. Thank you and I look forward to hearing from you guys.
