A decent HU will have at least a built-in sub crossover and you will get sub out and line out. A decent amp will have high-pass and low-pass settings for each set of channels to prevent the exact situation you are describing. (components have crossovers in them as well)Uh... The speakers will try to play all the frequencies... Won't they distort and sound pretty much awful...? Think of a 6.5" speaker trying to play down to 40 hz... Or a subwoofer playing what a tweeter puts out. (IDK what frequency tweeters play at... I want to say somewhere around 10,000 hz...)
and you just missed a Brax 5-ch. in the classifieds.
