how much does the head unit matter?

[Craz1000]

pretty much clipping is when an audio signal is cut. its hard to explain but ill try, imagine a perfect sine wave, where the peak for the waves represent 12v and -12v ok now cut it at lets say 10v, what youll have is the part of the wave thats supposed to go past 10v or -10v is flattened at 10v. thats clipping the peaks are clipped or cut out of the signal because the source isnt capable of output pas 10v so it flattens the wave

my color scheeme in my car is red and the only red decks i find is sony

Alpine actually makes a deck that can change its colors, CDA-9885 is the model number, the buttons can change colors dont remember if the know dose too. they also had a model 2 years ago that did also. also almost every radio youll find at Bestbuy/Future Shop is 50x4w with 2v or 2.5v preouts
