I bought 2 sets of these speakers for my car. I had in before kappas 652.1i. The old more powerful kappas had such a difference in mid and even low end bass. The only thing better is the polks highs. Can it be because older speakers didnt have built in crossovers? The older speakers have 20 watts more a piece so i know its not a power issue. What if i take off the crossovers. Opinions before i tear these piles of junk out of my car
