Hi i have a 2.3 CL. I need help planning with my amp installation. I am poor so I have to do it one step at a time. I am planning to have two amps. one for the subwoofer, and one for the speakers (6.5 and 6X9 , maybe tweeters) in the car. How do the two amps connect to each other? I going to have it done by somebody so I need to know wat to tell him. Can i just have one AMP installed and then just have another amp piggy back or do i have to have a seperate line or should it be spliced from the main line. Let me know what is the best way to do it. Thanks!
