Well being a complete newb at this...... i have bought a 80.4 amp from jbl for my highs in my car to go along with my JL 250/1 & JL 12 inch w6 combo. The question is for all the settings on the back of the JBL 80.4........ i duno what to sett anything too.... it has 2 switches called x-over that have settings of flat, hp, lp and under input mode has 2 switches that have option of ST, MD. It also has 4 knobs, 1 under each xover that have 4v, 250mv on end of the knobs, and one under each input mode switch that have 32hz-320hz on each end of the knob...... what are optimal settings for me? Right now im just powering 2 infinity 6x9's and 2 6.5's that are in the car stock. Please let me know what all these switches should be at...... i dont want all highs/bass like i hear in most peoples systems..... i would like my 6x9's to still put out a little bit of high end bass/midrange...... Please help, thanks.
