ok heres the situation...ive been doing some research before asking...last night i installed my System which is 2 12" Sony Xplods, 1200 watt sony xplod amp, with an 8 gauge cable... but it doesnt seem to be hitting that hard for some reason?!?! i havent tweaked the settings on the amp yet, cuz it was really late last night..would that fix my problem?? is the gauge not big enough?? and also...when my system is on, it is making all my lights dim, almost like its pulsing to the music... If i got an Optima battery would that make the dimming go away? or maybe put out more sound? if so, should i get red or yellow top?? also what about if i got a cap? would the cap make things better?? please help me! im in need of help with only 3 hours of sleep last night.. THANX
