So I replaced the stock speakers a few weeks ago with some kicker front and rear. I only have a 4 speaker set, and I totally forgot the model number of speakers so I wont be able to check that. The question I have is how do I stop distortion at high sound levels in the rear speakers. Once I turn it up past a certain part it starts distorting and sounds really bad. All I want is some good bass coming from the rear speakers with out buying a sub-woofer just yet. I have stock stereo too, I'm wondering whether I should just buy a small amp and see if it will do what I want, or should I invest in a new stereo too, because that's going to be a pain. Front speakers only distort at super high volume so I am not worried about those. Just rear and easiest way to stop some distortion.
