How would you be able to check if speakers are wired properly? i have component speakers at the front, coaxials at the rear and a 10 inch sub. Is there a way to test if all these speakers are sounding the way they should be sounding?crossover and tweeter... Is it enough to tweak settings on HU and change front, rear, left, right, on-off of subwoofer and then listen where the sound is coming from?
