How to tune your system......starting with basic crossover tutorials, etc...i have a pair of ADS components and am getting too much bass through them. What should i set the crossover that came with them at -3, 0, or +3 (i think thats what they say)........Ive got the headunit bass crossed at 80 hz.....or could it be the amp is under powering them...im running a PPI art a300, ADS comp set is 346cs. Thanks, Stewart
