ok guys I am not really a pro at car audio but here is my attempt. It is a jensen 600W amp with two sony 10 inch explode subs. so i have the subs in series so that doubles the resistence right? i figured this wouldnt blow up the amp lol. also the amp has two channels and a single amp channel that puts out 400 watts i think. just wondering on other things i can do to get the most out of my system by tweaking it and whatnot. Also i will try to take a pic of the subs at night because i installed light in the bow and the subs glow an awesome sade of red. thanks for the help guys.
