i dont care haw well you intall a boss/pyramid/or what ever cheap crossover - it still will give you noise!!!!!
there is still alot to be said for the higher end - known brands, they cost more because they do use better parts, and yes you do pay for the name but someone is paying for r n d and then the cheap companys just copy them. now can the average person really hear the difference between apple to apple quality brands - i dont think so, can i maybe - maybe not. and yes install has a great deal to do with performance, sound quality, staging, or amount of and tone of B A S S.
